Sucks. Give up hope! lol. Mine dropped an exhaust valve on my black bike and I haven't touched it since. Parts of the exhaust valve stem fell out the header. Will need a valve/piston and combustions chamber work on the head at minimum. The way things are going at local race tracks, I may never fix mine.
If stock springs, then boost pushing against the spring could have caused it to pop the valve keeper off the retainer, then the valve drops and hits the piston. But who knows.@@MIGHTYDQ
Who knows and you might not ever know, bottom line is it's broke. Every time I think about pulling my motor out, I get more and more bad news about the track, and it just doesn't make sense to spend money on it when there are less and less opportunities to race it.@@MIGHTYDQ
@@quick99busa I hear ya. Soon as we figure out what's all broken I'm ordering parts. Have a head already. I know I need a piston. Hopefully the cylinder is salvageable
