Re: World of Sprockets!

A worn sprocket set would affect the performance negatively mainly due to two reasons. First off, the power deliver is not linear, in the sense, when you engage, there is a whiplash effect where the torque is lost to an extent and then all you get is the clutch drive. Second worn sprockets will always loosen no matter how much you tight them, second the bike will lose pickup and not respond to small throttle inputs correctly. It will jerk, or you will hear a thud sound from the rear.

When you change the sprocket, change the sprocket in a set, so that both the lives of the chain an sprocket lasts long. Change just one, and the part you replaced will worn sooner.

Re: World of Sprockets!

Thanks for the detailed reply B7ACKTHORN. I'm planning to get them replaced as soon as possible as it's long overdue. I did notice a few of the things you mentioned happening to my bike so I guess it's the sprockets. Thanks Again.

Hey bro, I was thinking that it maybe the clutch too but I think 30,000 kms is too soon for a clutch to wear out. How long did the clutch plates last before you had to change them?

Re: World of Sprockets!

A good clutch plate will last over 40k+ would you believe I changed my Victor's clutch plate at 70K KMS on the ODO! And it still had quite the same punch. It all depends on how one uses the bike, frequent usage of clutch will prematurely wear the clutch. And clutch drive, meaning fingers on clutch always will put some pressure on the clutch and will lead to quicker wear. But a good clutch plate should last 40K plus depending on the riding conditions.

Re: World of Sprockets!

I changed it two-three months ago... odo reading ~ 68-70K..

Re: World of Sprockets!

I own a 2011 220f and done 17350kms and i lube my chain every 1 and half months,does chain lube increase the life of chain and Sprockets and how much time a sprocket lasts!!

Re: World of Sprockets!

Sprockets don't have a set life, some last long, some don't, it's all well how one lubes the chain etc. Lubing the chain definitely will prolong the chain life as opposed to one that isn't lubed or looked after. A good sprocket should last 20k minimum and some even last till 40k but it all depends on how well the chain is lubed, slack adjusted and take care of, especially the naked chain types.

Re: World of Sprockets!

hi guys,

I need to change my rear sprocket (P150 UG4). I just want to know that is there will be any kind of performance change or any other kind of upgrade if I change the chain and rear sprocket with that of P180.
[MENTION=24386]Samarth[/MENTION]-619 please provide your valuable advice.......

Re: World of Sprockets!

Sorry buddy, I was at Office, and plus, was caught up in a problem online too, on Xbhp itself. So, couldn't attend to your query.

Which P180 buddy? UG3 or UG4? Most probably, UG2 and earlier P180's kits might not fit at all. So, you can choose only UG3 or UG4's kit. If you change your entire setup to P180 UG3's kit, you might gain a little more top end & relaxed cruising. That means, slight overgearing.
UG4's kit will overgear more, but its a heavy setup with a .520 chain pitch.

On the other hand, let's check out gearing values:

Stock (I think P150 UG4 has 44 to 15 configuration, can't be sure, please correct me if wrong) = 44 (sprocket teeth at rear sprocket) /15 (front sprocket teeth)

44/15 = 2.933 (Stock Final gearing)

After P180 UG3's kit: 43/15 = 2.867 (overgearing, slightly, comparatively relaxed)

After P180 UG4's kit: 39/14 = 2.785 (more overgearing, more relaxed setup, but lesser acceleration)


Also, please note that if you change your entire kit to P180 UG4, you will have to keep the chain at its tightest setting from the starting. That means, if the chain loosens later on, you'll have to cut links from that extra long chain to tight it again.

The UG4's chain is 65 inches. (5/8 inch chain pitch X 104 links) Your normal UG3's chain is 62 inches. So, mind it.
I too have a P180 UG4's kit on my Pulsar 180 UG3 (now 208cc). Its doing good, just needs frequent lubrication.

Re: World of Sprockets!

First of all thanks a tonne for your valuable reply.I do understand your problem as I get time to access XBHP when I am in office only. Well I have decided to not to change the sprocket. I was looking for a more relaxed crusing but the process seems to be really cumbersome for me. Actually the problem started when my rear tyre was rubbing with the chain also the local mech told me that my sprocket is due for a change but I was not solely convinced so I went to Bajaj ASC and they confirmed it that I can still run on the same kit for few more kms so finally I decided not to change it now and ended up changing my rear tyre. May be I will take out some time to hunt a P180 UG3 sprocket kit.

I was having big time problem with my chain and also in higher RPM my bike used to behave very indifferently specially with pillion on board, it wasn't maintaining straight line. After changing the tyre i have recovered my problem. So not much in mind set right now to change or alter the default sprocket kit. Again hanks a lot for all the info shared and clearing my doubts and helping me sorting out my problem.

Re: World of Sprockets!

Apart from R15v1's 42 teeth rear sprocket, what other options do i have to under-gear (more towards acceleration that top-end) my FZ ? Stock are 14/40.

Re: World of Sprockets!

I think Apache 160's 13/44 and 180's 14/46 might help you under gearing!
You can also try out the rear sprockets of R15 V2.0 and duke 200 which are 47 and 44 respectively.

Re: World of Sprockets!

But these would change the ration drastically.
What I have read in this thread is +-@ is fine, but more than that starts affecting the performance/handling in a negative way.

Re: World of Sprockets!

I have just now finished a thorough study on web about gearing. It is clearly told that it wouldn't affect the performance in any of the ways. What exactly happen here is that the output if used in the desired way that it.
Apache 180 sprocket set wouldn't bring in a huge change! O.o

Re: World of Sprockets!

Thanks. Looks like I should also do some more reading about this. I just read this thread.
Ya, I know that. It only changes the way of power delivery, the orginal power remains the same.
I will check the 180's sprocket. I hope its a direct fit.

And one more thing, if you know, do the svc sell individual sprockets or only the whole set with chain.?
I guess a visit to a couple of svc is required.
