Ticking Noise 00' 400EX
#1
Can anyone tell me what this is? I have a ticking noise coming from the motor (usually when cold). As it warms, it starts doing it only for short times, just when you rev it. It will do it for a while but after about 30 mins of riding it gets hot and quits doing it most of the time, but still every once and a while it'll start it again. I also have a hard time getting it started in the morning, and once you get it started it kind of sneezes through the carb for a while.
Can anyone help me out please? Thanks alot.

Piston slap is caused by excessive clearance around the pistoon. As the piston heats, it expands and the noise usually goes away. A mild case is no big deal. If it was a major problem from wear, you'd probably be smoking and burning a little oil and it would be time for a rebuild.
From what you're saying, I'd try to have the valves adjusted.

i heard a small ticking noise comming from my quad.....i had just rebuilt it and everything was up to spec. I re-adjusted the valves and everything....if its loud it may be from a loose cam chain. Myne isnt that lound and i know everything is fine so its all good
