I made one block out of 2 TR1-blocks.  But there's a tick in the front cilinder. And he doesn't run properly. I checked the valves/clearing already , but I can't find anything.
My question is:  Is it possible that I build my block , the wrong way. for instance: is it possible to set my "nokkenas" upper shaft 1 bracket to early or too late , without destroying my valves when starting my bike ??
Furthermore he shooked at 4000 RPM at intervals while driving.  Can it be something else , then a vacuumproblem??
I hope I was understandable for you and somebody can react on my question.
greetings Jos
