@ Only Amit: That's great experience. Even I have noticed similar things when I overgeared my P180 2 years back...
Like you too, I wasn't exactly able to get better mileage in the city... It was more or less constant. Because, in the city, you can always choose one gear lesser...

Karizma already has tall 4th & 5th gears in stock state, so no doubt you had to downshift.

@ Abhay: No, I don't mind. Thanks for simplifying it...

The legendary and the one and only Suzuki Shogun
It is even better than the R15 in peakiness.

Thanks a lot guys, appreciate it, yes I'm new to the mechanic division so I'll take the bike to a mech and get it done from and learn one more thing, if I change to the karizma's sprocket, my engine isn't tricked out as your (abhayshanu) engine is, so is it advisable to do this mod ?

hey friends,would there be any significant boost at top end,if I replace RTR 180's rear sprocket(46T) with RTR 160(43T).
please recommend others if possible....
Would it have negetive effect on the engine??Doesnt matter if pick-up is dropped.
I am also changing my rear tires to 120 (previously 110/90) IRC tires.

thanks..

RTR 160 has a 44 teeth rear AFAIK... And also, their workshop manual suggests that they are not interfittable parts...

You'll have to approach street mechanics to "try and fit" sprockets from other bikes. Don't replace the chain as yours is built for the open chain setup...

If you go for a 120 section tyre, it might modify your gearing slightly depending on the second value (the profile)... Try 120/80 for the same gearing as earlier.

@ burninrubber: 3 teeths is within the advisable level even for a stock bike... Don't go beyond it.
Here you are going 4 teeth up. So, I suggest you get the new P180's rear (39 teeth, may fit) or P200's rear (38 teeth, will fit).

If you still go for zma sprocket, you might not get enough top end and a lot of non-relaxing highway rides.

I have used the zma sprocket, and my bike was stuck at 142 kmph, nothing more, my bike with 37T hits 151-154. So you decide if you are fine with 140 kmph?

need somw help

Guys,

i won a 2005 pulsar 150 ug2 ODO is almost 40k i wanted to know that what is the Aprox life of the company sprocket? how will i come to know when i have to change?

When your chain hangs down with a lot of play, more than 35-40mm on the lower part, its the right time to adjust it.

When the chain is already adjusted to its maximum limit, and still it is loose, its the right time to replace it.

Usually, chain-sprocket sets last from 20,000-30,000 kms depending on the usage.

So, if you have not changed it till now, I recommend you get it checked and adjusted, or even changed if the Bajaj showroom mechanics recommend replacing it.

Finally someone who has actually used p220 chain . Appreciate if you could share how you did the following..
1. Added the extra links.
2. Are extra links available or did you have to buy 2 chains.

I always wanted to use the o-ring on my Zma, but due to shorter p220 chain, have been reluctant to do so.

My mech who told me to replace it as its almost worn out. as you said earlier in this thread can i change it to LML freedom sprocket? presently im running stock sprocket with 44 teeth (its written on it. i dint counted). so what will be the effect or difference if i switch it to 40 teeth Freedom's

just a query about my stock R15 sprocket, what if i replace the front sprocket with one teeth lower than stock one will that give me a better low end torque and what will be the effects in fuel efficiency?

Hey guys I am owning a RTR 160 carburetor model.
Ill be getting my bike Joeled very soon. Im purchasing the 170cc big bore and freeflow exhaust from him.
He said that both these parts will give an increase of around 4 bhp in the crank over stock i.e 19.2ps i guess.

With so much power I want a good top end for my bike without much loss of acceleration.
What sprockets should I fit on my bike?
Also whats the true top end of a RTR wid stock gearing?

Please help guys.

As I came to know that P220 has 36T in the rear. What can be done(increas/decrease) to increase the fuel average of the bike. A compromise on accelaration is not an issue.

I am sorry I am not very much into machinery so have a little knowledge of use of increased/decreased tooth of sprocket.

44 Teeth. I think you have Pulsar UG3, with digital meter? If yes, then it won't fit.
The Freedom sprocket has 6 fitment holes. Only Pulsar UG2 and earlier supports this sprocket. Your UG3 has 4 holes fitment.

But is it really Pulsar UG3? Tell me your bike first, then I'll let you know what fits it.

@ tusharsmolly: You can just use the 14 teeth front sprocket from R15 to overgear your RTR 160. Or you can tell Joel to do it together with other mods.
It should carry itself good enough, because a bike modified by Joel raises hell at all rpm's! Don't worry about overgearing!
With stock setup, RTR 160 achieves some 118 kmph real top speed. Meter may display some 125-128 due to the common speedo error.

@ Blumarine005: Sorry, as of now, most bikers can't suggest overgearing the P220 by changing one sprocket, because its chain pitch is .520 and other bikes having .520 pitch (ZMA, P200, etc.) all have undergearing sprockets.
-
@ srinathrao: Yes, it will undergear. You will get better acceleration in all gears. Highway mileage might take a very slight hit. But in the city, you won't lose much on the mileage front if you ride the same way as before.

Top Speed

Hey Guys i have recently got my rear sprocket changed from the service center and what i notice after that is my top speed has gone for a toss....i could do a 130 with ease even with a pillion but not even on a single seat i hardly touch the 125 mark....my bike is P220 FI 2 yrs old now and i use the same engine oil castrol active which the service center guys add....could somebody shed some light as might this be a possible different sprocket put on to my bike instead of the one which should have been...
