Hey everyone, i just bought a a new bike well newer to me its a 2000 yz426fm and I'm a bit concerned with a noise (best explained) as a rattling noise or a constant ticking. the bike never made the noise when i bought it and that was two weeks ago. it started slowly and now it is constant hot or cold at idle and at high rpms i dont think i have even put 100 miles on it. I thought it might have been one of the few issues that others have encountered with these bikes, so i took it to a so called reputable mechanic to get it fixed here is a exact list of what they claimed to do
Removed fuel tank assembly and valve cover
Checked valve lash
Intake .006 and exhaust .010-both within spec
Check timing chain tension-good
Reassemble valve cover and re install fuel tank assy,
Check oil level and condition-good
Remove RH side cover, clutch assy. and check counter balance shaft key-good
Check both sprocket nuts-tight
Re bend washers
Reassemble and re install clutch-good
Re install side cover
Refill anti freeze and case oil
Nothing found out of spec.
Good to go at this time.
They charged me $232.77 for that and the bike is still making that noise to me it sounds as if its getting worse I'm scared to ride it any more I've heard horror stories about what happens when you let something like this go. Please if any one has some real advice, past experiences or ideas about what else it could be it would make my day.
