Valve noise

[Eviltanker]

O.k. question for all the EX owners. I'm not familiar with 4 stroke stuff let alone EX's. I have a decent amount of valve noise in my wheeler. the service has been done and I was told the valves are good. Is this normal for an EX? I'm running Honda oil and 92 pump gas. Any help would be appreciated. Thank you in advance.

i have an 06 400ex and the valves make a good bit of noise. This is apparently very common on these bikes. I have had the valves adjusted and they say everything is goood.

i have an 05, the ex just has a noisy valve train :ermm:

Ok guess i shouldn't worry then. just seemed loud to me.

You can go and check the valve clearance on the bike if you want to make sure its ok. Its pretty easy and i can explain it for you if you want. But valve ticking on these engines is very normal....almost all ex's like to make some valve noise

[Eviltanker]

If you could that would be awsome.

Yeah... the EX's all have noisy valve trains. Nothing outta the norm.

The time to start thinking they need adjusting is when you CAN'T hear them clatterin.......meaning they're too tight again.

OK so noisy is good quiet is bad.

i have read that if u put in a cam they make more noise as well. i have a stage 2 magnum cam in mine n it just sounds scary. at an idle there is almost no noise but once i pass about 1/8-1/4 throttle it makes so much noise i think its gonna blow up... again! i have done the valves once n it didnt help any n i just got it back from the shop 3 days ago n they say its good but it sounds the same. lemme kno what u guys think
