As we know Indian market is fast growing market in two wheeler segment due to large amount of interest in biking and so demand due to lack of imported motorcycles. So generally people tends to change the machine from stock to high performance for either street racing, circuit racing, drag racing or for dirt purpose. Earlier some of the high performance material was not available in India due to lack of knowledge about material or because of importing it to India.

increase-motorcycle-performanceNowadays in India there are some high performance spares available by some of the direct distributor or importers, for example K&N filters, Piper Cross, MSD Ignitions, NGK, DYNOJET, Microns, TwoBrothers etc. The material is extremely high performance but just by putting few spares you can’t increase the performance due to lack of information. The performance is depending on channels or the way you put those spares in-line. In simple language it’s a kind of computer flow chart.

In the market some people just trying to do business for money. Anyways lets talk about the high performance for Indian motorcycle. Lets start from Filter, In the market you get K&N or Pipercross, LM filters or BMC filters or whatever. When rider or mechanic installs those High Free Flow Filters they generally forget or don’t change some or the other things just to avoid complications.

High Free Flow Filters means Air without any obstruction or rather than increase in Air quantity. Stock Motorcycle comes with some particular ratio of Air and Fuel. For example if the stock has got 5:1 ratio that means 5% is air and 1% is fuel. Now consider Air with Free flow filter is 10%, people always forget to increase the fuel ratio, that means fuel should be 2%. So when you are putting High Free Flow filters don’t forget to increase the ratio of Fuel by Re-Jetting.

High or low number jets are available in the market or you can get it from some local manufacturer with accurate required numbers. Dellorto/Spaco has got jets but not suitable for Mikuni or Keihin because of thread size. In Two wheeler all Indian bikes are coming with Mikuni or Keihin carbs. So make sure about thread sizes. so after Re-Jetting next step is burning all the fuel, that means change in spark plug (NGK-Ir), change in spark plug cable (MSD Ignition Cables), High performance Ignition coil for better and high voltage for burning the fuel.

Next step after plug and it’s cable the main and priority change in Exhaust canister, which people always forget or ignore or avoid to use High Performance Free Flow exhaust canister. The reason behind Free flow high performance canister is, when the intake is increased by some amount the exhaust should also go in that ratio which stock silencers can’t do. For that reason it’s priority to change the canister from stock to high performance (TwoBrothers, Microns, etc). In all mods the channel of modifications should be in route for good performance. So this is the main flow chart for modifications in Indian Motorcycles without tinkering much and very much easy because of external changes. For ECU controlled or EFI system and Carburetor motorcycles some of the modifications are common, But EFI needs some different modification due to it’s ECU, which we need to remap for high performance.

Don’t forget to work on Lubrication for better performance. In the market you might get some high performance lubes like synthetic, semi synthetic oils. Oil is the main factor in the engine for performance, wrong oil grade can decrease the performance rapidly and might damage the motor or moving parts.

Please note: Some of the imported oils are not suitable for Indian Motorcycles, they are very good for Higher CC engines. The major lag of power starts from clutch, so wrong oil can start slippage in clutch. So make sure before you buy and pour in the motor. Now lets move on to Internal changes which I call COREPOWER.

The first change should be clutch springs, the main engine power transmission is through clutch so bad clutch springs or low tension springs kills the BHP, so use proper tension or some high tension clutch springs which should high tension than stock springs. The second step is nitriding of intake and exhaust valves and so the cam, which will reduce the wear and tear. Somehow if you are able to get titanium connecting rod, Valves then nothing like it, but sadly for Indian motorcycle it is still not available.

Anyway, so the next step in internal change which is Big Bore Cylinder. Change to higher size piston for big bore cylinder. After that next change should be Hard Chrome Plating on cylinder bore, which helps the piston for fast motion. The next step is increase in intake bore for better intake. After those changes you will definitely get high performance from your Indian Motorcycle.

    Nice article there with all the basics covered. Most people tend to overlook the important points like re-jetting and better spark plugs. Waiting for a similar article on FI mods.

  • FZrider

    Very nice article…..could you tell me for my FZ-S what neccessary changes required to get better performance?

    and if you could please give some price estimation also.

  • Chinmay Dangre

    In YAMAHA FZ-S the carb. is BS type so check the stock jet first, then try to find higher number jet for re-jetting. for example if your stock jet is 100 then try to find 110, 115,120. Then you will see two rubber pipes which are connected to Air Box. One is for emission controlling kit (AIS) and another must be for crank breathing. When you are fixing K&N you need to put this filter directly on the carb by removing the stock air intake hose. Then try to find one more small filter to put on crank breather because you will be disconnecting that breather from air box. Then shut of the emission controlling kit(AIS), if you don’t then impure air will enter in your emission kit and when it will operate it will also use the vacuum from carb which is basically obstruction. Then ride your motorcycle and try to see if it gives you problem or not. When you are riding at a high speed if yes then go for re-jetting with higher number of jet. But in all this procedure if you keep your silencer stock then I suggest your all efforts will be in vain, because the more air you allow, engine needs to exhaust gas in that ratio. Catalytic and the stock baffle will not allow to do free exhaust. It always need a free flow silencer…….In this all mod get skilled mechanic

    • jainamshah

      my name is jainam shah i m owning a fz … and i wanna a add a muffler in it so plz let me knw if u can the part to mumbai via sum services … thnx

    • Jaxz

      I would disagree with the disabling of the Air Insertion System. It only provides very little boost to the torque but it will decrease the top speed, in fact the torque gain is so insignificant that it is not worth it, as the idle timing will be adversely affected, causing very tedious carburettor tuning.

      What you need is to modify the mikini carburettor by drilling and enlarge the holes of the Slider of the component. This is to increase the vacuum flow.

      2) Change to a high velocity air filter like K&N Stock. Pod K&N Filter is not ideal as it is susceptible to rain especially if these bikes are bought by customers staying in tropical countries. Besides, Open-Pod filter will not give top speed and in fact will decrease it. Lastly, Open-pod filters are very prone to dust.

      3) Change the CDI to a custom racing CDI. This I leave it to the people to search for it in the internet. There are some enthusiast who have created a racing CDI for this model of the bike.

      4) Mod the piston block. Enough said.

      5) Change to a high exhaust like Yoshimura Pipe.

      These are the only things one can do to increase the performance.

    Thanks alot…..but i dont wish to change the stock silencer…..shall i only install a K&N filter and a NGK platinum [Ir not available yet for FZ-s] spark plug….will it increase any performance??

    • Chinmay

      Hey thanks a lot man, but will it affect the mileage ? and if yes then how much will it be reduced to ?

  • Chinmay Dangre

    Can’t say, but I guess that will change only low and mid range but not high range…choice is your’s goodluck….So if you wish then try it….

  • Chinmay Dangre

    NGK (IR) – part number for YAMAHA FZ = CPR7EAIX-9

  • FZrider

    wow…thanks i will look for that….

  • Chinmay Dangre

    Dear FZRider,
    If you are from pune, then you will get this plug from Pro-Biker shoppe which is near to ABN Amro Bank. For more details you can visit my workshop.

    — Thanks

  • vicky

    I am a fz16 owner n i want to change my stock exhaust…would u plz tell me that with which exhaust can i change it..i am thinking of under seat exhaust…if i will make custom exhaust wat would the size,length,diameter etc..with which i can get maximam performance…or can i get any under seat exhaust…plz guide me

  • I have been looking looking around for this kind of information. Will you post some more in future? I’ll be grateful if you will.

  • Chinmay

    Vicky, wait for DAYTONA.. all the performance spares will be coming soon.

  • sagar

    thanx alot chinmay.i’ll get in touch with u soon.

    hi you mean airfilters n other stuff as well by DAYTONA….

  • subrata

    I want to take a new bike within 2-3 weeks, my choice is HONDA UNICORN or SUZUKI GS 150R. Can one suggest me that which one is better. Presently I am Using RX 135 (5 SPEED) from the year 1990.

    • anil kumar

      hi. Keep using the rx. Best bike. Get it tuned up and i am sure it should serve another ten yrs. Buy off some spares and keep it. If u still wanna buy a 4 stroke u can take the hero honda for economy any cheap running cost. Dnt sell yr rx .

  • Chinmay

    @ subrata,
    I am really very sorry for late reply.
    In some points Unicorn is good and in some points suzuki is good. But as we know the unicorn rolled out much before SUZUKI that means no issues with unicorn. But SUZUKI is also big manufacturer so they will not make ne mistake in GS. I road the GS150 n I found it’s cream.

    I just got the mail from one of the yamaha dealer that the DayTona Kit will cost near to 53K.Will let u know all the Daytona kit details soon.

  • vicky

    thx chinmay…
    one more question…
    there is any way to put some parts of daytona kit…bcoz i cant afford 53k ….

  • Chinmay.D.

    @ vicky, I guess the kit I have mentioned should be open kit so i dno’t think so it is kinda of a package which u’ll have to buy fully. So u should be able to buy separatly in spares. besides if the kit is available in spares so prolly u can go for Exhaust canister and remapped ECU. other things i don’t think u need ’em. But I suggest wait for some more time coz yet there is no news from people or any magzine about the review. I heard that they r not worth coz the kit is hardly increasin some BHP. Well in that case I don’t know what people exactly did. But this is what I have heard.
    lets wait n watch………

  • raj

    hey nice info……………

    Dear Pavan,
    Please let me know your city. If you are from Pune then I can guide you.

  • Jai

    Hey Chinmay

    Nice Article !! I have a pulsar 180(2007) which i wish to modify .I am planning on putting a K&N filter (1060)+ jetting , NGK spark plug and sproketting (top end speed) . Can you tell me where in pune i can get these parts and a mechanic who can fit all these (wud be nice if you can list out the prices also ) . And do you recommend i go for all these modifications ? (I want some performance ya !!!!!!! )


  • Vicky

    Hie chinmay.
    Plz suggest me…i want to change my rear sprocket mainly for stunting…wat size of sprocket should i use…i hv fz16

  • Chinmay Dangre

    @ Jai, If you are interested in changes then you can come to my place. I do marchandising and fix it too. I am from Pune.

    @ Vicky, If you are not worried about warratny then you change the sprocket. B’coz Yamaha is very much tight about warranty issues. For stunting you will be needed bigger size rear sprocket. But by that you will loose your top end. It won’t go more than 70 to 80 is it ok with you? Please wait for my next advice for the same, since I don’t have calculated sprocket for FZ. So I will let you know about it.

  • Vicky

    Thx chinmay.
    My warranty is already broken…so warranty is not an issue…..n i dont drive my bike above 100 bcoz i alwayz driving in cities n traffic….i use highways very less..wich size of sprocket is suitable for me.,

  • Chinmay

    40 or 42 teeth sprocket. Also try to work on your Pilot Jet. Up-Jet the PJ for low end reving. But careful b’coz FZ carries huge n bulky n heavy weight tyre which is already loading the main shaft in the gearbox. So by changing the sprocket and jet the total load will come on main shaft, chain kit, clutch.

  • Jai

  • Bhupesh

    Hi Chinmey
    Nice to see the all info at one place, what is more amazing is you do this professionally.

    I owned a Apachey RTR 160 its 1.5 years old, i some how very much like its control and handling compared to pulsor- its equally stable at high speeds and at curves, top speed is also good 115-120(off course what more can be expected by this low end bike). i dont want to buy a pulsor 200/220 just dont like the brand and its not much worthy to go for apachey 180(maybe wating for tvs to bring in 225cc model that wud be ideal).
    In the mean time i wish to update my present bike. please tell me how much bhp(present is 15.2) and top speed can be increased against Rs15k-20k budget.Also if say i need to boost the performance to 18-20Bhp with no significant improment in topspeed which i belive is not possible, how much cash will i have to lose.

    Thanks again for putting up somuch usefull info for indian low end bikes.

    Hi chinmay

    I have fitted kn filter and iridium spark plug in my FZ16, the air hose linking carb and air box was removed and conical kn was fitted directly on carb. My confusion is that the air box is open now at point where hose is removed and further no pipes were closed and no other filter was put in place. I am not knowledgable abt where each pipe is going,cn u plz tell me whether i have to close pipe or the open point in air box(at which hose was conected). It would be great help if someone cn suggest me a real gud mechanic in chennai who knws stuff well

    Hi Chinmey!

    I wish to increase torque on my Fz16 for stunting … will a larger sprocket in the rear do the trick ?? if so which one will I have to buy and how much will it cost me??

    • Abhimanyu Raj

      It ll cost ur life.
      ha ha ha ha ha

      • Abhimanyu Raj


  • @ FzLowONTorque.

    Go for proper pilot jet upjetting and rear sprocketing,,,since u want initial torque or the power or the pick up. u will be needed big size rear sprocket..but don’t forget u w i loose top end…and some things might worn out faster than it’s actual life…

  • FzLowONTorque

    Ok!! then thank you for that 🙂

    what about the sprocket then ?? My local mechanic says the “hog needs to be replaced for this” is this correct … ???

  • DioDudes’

    basically for two-wheelers like HONDA DIO and HONDA ACTIVA the mods are as follows-
    1> you can change the air filters..
    the two options are k n n air filters and pipercross air filters.
    pipercross air filter has proven to be the better one..
    both of them come for the same prices, ie. 1650 bugs
    2> you can change the engine oil
    mobil 1 oil can be used in your bike. it is a synthetic oil which improves the engine output and efficiency. it would cost around Rs 900 per litre
    3> you can change the spark plug
    a ngk irridium spark plug is most suitable for any indian bike..
    it comes for 550 bugs..
    4> you can change the ignition wiring
    Msd ignition wires are best suited for honda dio and activa. it comes for around 650 bugs per metre.
    5> you can increase the petrol supply
    petrol supply can be increase by jetting. it hardly costs 100 bugs

    thats it.. get these things in your bike and experience the change…
    these tips can be implemented on any bike..
    keep revvin’

    thanx in adv

    am looking for K N filter what is the cost n pls let me know its for my avvy 220

  • andrew


    1) Go for a larger front sprocket. so if you got a 14 teeth, go for 15 teeth and so on. i got a stunner pgm fi and i’ve got a 16 on it now and i’ve GAINED 10kmph top. it shouldnt cost you much

    2) Get a free flow air filter + a free flow exhaust fabricated (costs around 8k) for maximum top speed benefits, dont use just either one it wont even increase ur top end by 1kmph.

  • tamzid

    i envy you guys for getting this kind of help directly… i am from bangladesh and i have been looking and trying my best to get the best out of my bike with whatever i can get a hold on to.. i have a stunner 125 and i want boost its performance please help me out on what do i have to do in a bit more detailed way since i am a newbie.. ill be ever so greatful for your support.. please..

    currently im thinking of installing the mechanical abs for my stunner which i saw just today in the market … is it a good idea let me know..

    im using castrol power 1 for my bike which is 10w-30 … is that appropriate for my bike? let me know.. please..

    im looking to buy a ngk platinum if anyone that i know goes to india recently (long switch??!??!) to replace my ngk r will that increase my performance?

    im also thinking about buying K&N filters for my stunner and just replace my existing filter will that work??

    please help me out.. im in desperate need of good advice.. 🙁 🙁

    • andew

      Tamzid, dont buy ngk iridium unless u want maybe 1mpl or 2 fuel savings, in terms of performance that plug will do no good, instead go for a larger front sprocket, 16T. u should be satisfied with that performance itself. u will be able to go 110 easily

  • Karthik Krishnan

    Hi, I own a Avenger 200cc. After reading your comments, I plan to install K&N filters, alloy wheels, Windshield to start with. Can u suggest any other modifications or performance changes. Thanks.

  • andew

    Anurag, your bike is quite new. let it be stock for now, but if you really want performance, try getting a free flow exhaust (around 8 or 9k) and a free flow exhaust, try getting SpitFire Ignition Cable for better fuel burning and spark. go with Fully Synthetic engine oil, and what is your top speed as of now?

    good luck.

  • Swanay

    Hi Chinmoy,
    First of all thanks for such a nice article. I have a Yamaha R15 ( 1st Version) which I bought on 2011, July. Already I have clocked 138 kmph as top speed and completed 4300 kms. Though tachometer is designed for 12000 RPM, it does not cross more than 10200 RPM. I asked in Yamaha Service center and they told me about Daytona engine kit as performance enhancer. But its too costly to be fitted with. So if I want to replace my air filter with K&N air filter and fit an oil filter ( if possible), will these help to improve performance of the bike ? please reply soon.

  • Swanay

    please reply fast guys… I am waiting for you suggestions…

  • fanpulsar

    better to change bike… dumb*** ….why will one spent so much money on spares and yeah indian motorcycles are really good in handling indian roads…there are no roads to drive in such a way tat u need performance oriented parts….

  • fanpulsar

    hi swanay u will have to do rejetting if u install k and n…performance will surely increase ….mileage and sound will be improved….i dont know about oil filter but installation of air filter will increase 4% of total bhp…ie …if u ha r15 producing 17 PS than it will be around 16.6 bhp and u will get additional 4.1 bhp……extra ,i.e, 20.7 bhp….so just install it

  • Gringo

    Hi Chinmay, I read your article and some of the answers you gave.
    Really shows that you know what you mean.
    I am from Argentina, I have a motorcycle Bajaj Avenger 200DTS-i, and with 5 other friends who have the same bike we tested various improvements.
    So far we tested two types of coil Nology high performance, but none worked correctly, down seems to lack power.
    We have even developed a CDI, which operates both spark plugs at once in the entire regime of the motor 100 to 11,000 rpm.
    If you want it, we can share with you this information, including e-mail CDI wiring diagram and photos of some of our “Indian” with tuning.
    We also believe that the flywheel could be replaced by another of higher performance.

    Could you give us any suggestions for improving the electrical system?
    Brand ignition coils and the guy who actually works for example.

    From already thank you very much by the time we can spend.

      This is to Gringo from Argentina. Can you send these wiring diagrams of the Bajaj. J. Dkhar, Meghalaya Shillong
