    Default chain rolling over sprocket problem!

    Hi guys, need a quick solution on this. I have a problem with my 200cc pulsar, it has persisted over the past 2 months, when chain rolls over the sprocket, more than 90% of the chain rolls over the sprocket smoothly, its only one part of chain which does not roll over smoothly. When I don't accelerate the bike loses its speed quickly, and its good for 1 or 2 weeks after the service but it re-appears again. Will regular oiling of chain will help or there is something else to it?

    First check chain slackness.

    Also, check all the individual teeth !

    check both the sprockets & the chain.

    my bike has done 15000+ kms. Chain slackness is fixed, the problem might be with sprockets, thanks for the replies.

    You may have certain section ( the one part that does not roll over smoothly) of the chain elongated. If it is the problem with the sprockets only, then the problem should have appeared on every rotation of the sprocket. Or you may have certian areas of the chain elongated (damaged) and defect in the sprockets and when these two areas match then the problem will appear.

    These are all probablities, so that you can check them out.

    See, it is a problem with the bike transmission as a whole. Now, the chain sprocket kit covers both sprockets and the chain. So, for replacing one part, you will have to replace all parts anyway. After that the problem should go away. Just clean and lube the chain regularly so it does not go kaput later.

    If i don't replace the chain sprocket kit, will this problem affect the performance of the bike or the regular usage of the bike further degrade the existing chain sprocket kit?

    If you don't replace; then there will be transmission(power) loss which would result in loss of power as well as fuel.
