Thread: Is that bolt right?

Started 1 month, 1 week ago by Christine
Remove all Advertisements How many of you have seen the bolt on the end of the exhaust cam on a 2005 RMZ 450? The bolt holds in the decompression lever. When I looked at the lever the bolt washer was tight and the washer was pressed hard against the lever causing the lever not to move. What's up with that? I took the bolt out and took the ...

I have a spare exhaust camshaft on my tool box and it looks just like yours, but I can easily move the decomp arm. Something is definitely wrong. Mine's an '08 not sure if that makes a different.

That is exactly what it should look like. I should know cos I just had to buy a whole new exhaust cam cos that bolt had backed out and wound up bending the decomp arm. It should move freely though. that washer should be resting on the slightly raised section in the center of the arm allowing it to move. Not sure why yours is in a bind. Why'd you take it out? Was it not kicking over?

If that weight can't swing out, the bike will run like crap. Just get a new washer and loctite that bad boy.

Ya, now were getting somewhere! I did do the new bolt thing but I'm think that the decomp is maybe bent.

if you loosen up the bolt a bit, does the arm turn freely?
