Afther riding the bike for two weeks, I fond out the when I acclerate or decelrate, there is some abnormal noise from the front sprocket, I have checked the chain the tension is not too bad, does this sounds like a chain buffer problem? I am thinking the chain buffer is worn and the chain is in contact with something, right?
not entirely sure what you mean bu chain buffer..
it sounds to me that your front sprocket is worn and the teeth have a wave shape and they are catching on the chain as it spins.
new sprocket time. :D
they are cheap and its worth doing when you get a new bike any way :D
Do you mean the rubber piece on the end of the swingarm that the chain runs over?? Unless its worn through and the chain is making direct contact with the metalwork I wouldnt worry about. Like Hmmmnz says........its more likely to be a worn chain/sprockets. The front usualy goes first, its smaller so it does more work. Get the cover off and have a look......use the Search function for info, there has been much written about the subject in the past.
It could be several things... Check your chain tension according to the manual (0.8 - 1.0" or something) and adjust as needed.
When chain tension is set, but the bike up on the center-stand in neutral and spin the rear wheel forward, listen for the noise, spin it back, listen for the noise.
Check to make sure the chain isn't hitting your center-stand. A loose chain or a missing center-stand stopper can cause this to happen. If you have an after-market pipe, they usually don't come with a center-stand stopper......
Check to make sure the rear wheel is aligned... If it's far out, it can cause the chain to kink.
Check for "tight links" in the chain... If it doesn't move correctly, it can also cause noise... In this case, a good clean and lube **might** fix the issue, but chance are you'll need a new chain.
If the chain is tight, it's not hitting the center-stand, everything is aligned, the chain is fine, and you still can't pinpoint the source of the noise..... It may very well be your front sprocket is toast.
The sprockets will wear depending on the maintenance... Mine front sprocket was COMPLETE GARBAGE and the rear needed to be replaced at 13,000 miles... But, the previous owner didn't bother to tighten or lube his chain. :dunno_white:
Anyway, I think I better replace both the sprockets and the chain when I some spare cash!
Thanks for advice!
