decompresser rattle?


Recommended Posts

well guys ive been having a problem.i own a 1997 xr650l with about 9k and i keep hearing a rattling or ticking noise when i start up the bike. its not real loud but loud enough for me to hear, and drive me crazy. i adjusted the valves, and kept checking them. there in specs. then i started thinking this might not be the valves. i took out the cam shaft and noticed the auto decompresser or whatever you wanna call it has bad case of the snake rattles. im not sure if thats normal. theres also some play on both sides. i made a short video of the bike running before the tore it down. and video of the cam. any help would be awesome. 👍

I couldn't tell that it was particularly noisy, but when it starts getting noisy and you can't pin it down, my bet is that your cam chain is getting a bit stretched and/or the tensioner may need replacement. If so, it'll start running crummy in an inconsistant pattern pretty soon.
