Valve issues

Recommended Posts

I'm just curious as if there are any tell tale signs that the valves are too tight or the spring is drifting around. I know that the best way is to pull the head and check the clearances but are there any noises or symptoms that go along with tight valves?

When you're starting to lose clearance, you'll notice your bike will run okay, but feel pretty weak. Then the next ride, you'll have trouble starting it and it'll feel like there's no compression.

...at that point, you'd be better off not riding it.

Those are the only symptoms I noticed.

We had a 450CRF -02 that was real hard to start, both cold and warm. That was all. It had run 40 hours, don't know what service was done to it before we got it.
