i have a 2003 raptor 660 limited edition. went ridding the next day when i started it up i noticed this clacking sound in my engine, the bike still has full power but this noise is driving me crazy, does anybody know what this could be, and how do i fix it thanks for any help.

 

is this noise abit like a grinding/rubbing noise? think ive got that on my rapture 700r?

 

prolly a trashed starter clutch

 

starter clutch? Im abit new to all this stuff.

 

"clacking noise" isn't very specific but the first thing I'd do is adjust the valve lash and then check for loose bolts on or near the motor.

starter clutch is the one-way bearing and clutch mated to a gear used to engage the starter to the crankshaft.
