Bonneville America Forums Forums Technical Forums Performance Mods Valve clearance

Hans,

Everything Phil said is good. I will add that when I did my first check and adjustment I had one intake valve clearance that was smaller than 0.04mm, how much smaller I don't know since my feeler gauge only went down to 0.04mm. After adjusting everything I really couldn't tell any difference. So I don't think you have to worry about damaging anything, but I would do the adjustment at the earliest opportunity.
