I have on '02 raptor 660 all stock and it has a faint ticking noise while it idles. A couple of my friends say that they all do that a little bit. Is this true?

Check the valve lash, should be around .0035 and .0055 inch...........

allright will do, does riding it with the valves a little off hurt anything?

To tight will make hard starts, and too loose will cause noise in the valve train........

You dont have to tear anything down, just adjust the valve lash............

How difficult is it to check and adjust the valves? I mean i have worked on V8s just never a small engine before. Cant be that bad right? lol

No different at all - just pull the valve inspection covers, set at TDC compression stroke and adjust em.

OK sounds like a piece of cake HA!

Once i have the valves set right and everything checked over are these 660s ever 100 percent quite running?

 

[QuadManiac]

No, there's almost always a bit of valve noise.

[Raptor_666]

[willykiller]

Use the appropriate feeler guage and adjust the ajuster until you feel light drag one the guage...........
