Alright.. so since the day I bought my 400ex, it has had a noisy valve tick due to the hotcam inside it. I have tried everything to eliminate this tick… I went back to stock (.04in .05ex), i went to what was recommended by a few on various forums (.05in .06ex) and I went to what someone supposedly was told from one of the guys at Hotcams inc (.08in .10ex… that’s ridiculous)!
So far the quietest it was ever at was .05in .06ex but there was still a noticeable tick!
Is there any right spec or do i have to keep guessing and pulling apart the valve covers over and over until i get it right? Or is this only something that’s going to go away if I get rid of my stock valve springs? Please help guys… I just did a rebuild on my 400 and I don’t want to hear this awful valve tick anymore :icon_ cry:
Maybe i should just let my local honda dealer take care of it *sigh*…
