So, R15 and FZ's sprockets are interchangeable? Thanks for sharing the info Anirudh...

You mean "2 teeth" I think. I agree that 2 teeth are enough, given the FZ's torque & the mileage it gives.

Hi Samarth!

I own a Fazer 150cc, the top speed which i have reached is 115 kmph

.
I want to increase my bike's intiall as well as the top speed!

Thought of changing the rear sprocket to R15's will it increase the intiall & top end

?

Pls do suggest wat to do ?

Signs of Clutch wear:-->

1. Less acceleration from standstill...
2. High revving, but top speed is less...
3. Less overall power, with specially the top rpm's not powerful like earlier,

Clutch Wear happens due to misuse (wheelies, road burnouts, jerky riding, etc),
constant city riding (in heat, or constant gear changing),
excessive tightening of clutch lever wire, which leaves the clutch engaged slightly,
or just plain Clutch "Ageing" (like after 20-30k kms of running).

If your speedo is working fine, then it does seem your clutch plates have a problem.
But I suggest you use them for some 2-3 k kms more. Only when the power loss is very obvious, should the plates be replaced. That's it...

Thanx for the reply budd.
Totally agreed.
but a query still remains, i want a bttr top end as u know my bike gets stuck at 110 currently as compared to the 120+ it used to do earlier(say some few thousand kms back.)
iv changed the clutch plates assembly just few months bck, including a new stock air filter along with the tuning of the carb and new chain/ sprocket. but my problem still persists.
I hope u wont mind helpin out, I appreciate it neways.
Thanx.
(P.S.- i have a '06 uni )

Hey are u sure the carb has been tuned properly? One of the reasons of losing top speed is running on an AFR that is too 'lean'.

I am not sure if the R15's sprocket is a direct fit to your Fazer, but assuming it is, remember the simple rule of thumb in sprocketing
1. Larger Rear Sprocket = More Acceleration + Lesser Top End
2. Smaller Rear Sprocket= Lesser Acceleration + More Top End

So, if the R15's rear sprocket is larger than the Fazer's, (AND IF IT FITS on the Fazer) then you'll get more of acceleration and less of top end than what you're getting out of the Fazer. In case the R15's rear sprocket is smaller, then you'll get more top end and less of acceleration.

Also, more than a 3 teeth change in sprocket size warrants a change of the chain as well.

Help me

Hi..I want to change back sprocket of my pulsar ug3 from stock 44T to 42T but the real problem is the sprocket is 4 hole setup and every 42T sprocket is 6 holed which i encountered .I am really confused which 42T sprocket will fit to my bike...any one plz help me which bikes sprocket would be a direct fit...

Btw i went to Rolon distributer and enquired about the sprocket models (F63(third link in bajaj manual) & F69(2nd link in bajaj manual)).The manuals provided on 1st page showed they are 4 holed but actually they are six holed.I personally saw the sprocket kits.So some of the information provided in the manuals provided on 1st page contains some error

**VarunRTR** · 01-06-2010, 08:00 AM

i swapped my RTR's front sprocket with a 14T one ,ie, 1 teeth more...but it had made a huge difference in riding pleasure.. Atleast 4-5 km incerase in each gear and the vibes at around 60kmph have gone. Didnt check the top whack but am sure it ll also be more . Now i can cruise smoothly at 60 and the speed in 5th gear at 4k rpm is now 58 compared to 52 earlier.

hey guys today i installed new rear sprocket for my bike, mine is a 4th gen uni n has a set of 15/43 sprocks, i wanted put 40 teeth one at d rear but my mech told only zma's rears is direct fit to my bike. n to my amuse he has put 38 teeth sprocks which he is claiming to be zma's, afaik zma has 40 teeth. i was shit scared dat my bike's initial will drop dramatically but guess wat even now m able to do a wheelie i havent checked d top whack yet but in 1st gear i cud reach 40kmph, i used to cruise in 5th gear at 80 n tacho read 6k rpm , now m able to reach 80 at 5k rpm will check d top speed n update tomo

bro i've a 4th gen uni n my mech has fitted zma's rear sprocket to my bike wid no mod, n uni has 43 teeth rear n zma has 38

so putting a 38 teeth rear on a fz wont be a prob but only thing is it shud be direct fit to ur bike. zma's rear which i've put costs around 600 bucks

Changing the rare sprocket to 38 teeth would this increase the top speed or just reduce the rpm rate. As Alok Urs said would it be a straight fit on the FZ.

dude it will defnitely inc top speed n mileage , m telling it from my own experience but see to it dat u get a sprocket which fits ur bike n has atleast 2 teeths lesser dan d stock. r15's rear is a direct fit for fz afaik, jus check out once
