So a couple of weeks ago I put a new piston,rings,needle bearing in my bike and when I put everything back together I realized I forgot to close my powervalve on my cylinder so the arm would connect to the bottom arm coming out of the bottom end. So I pull my engine apart again and make sure the arm is completely aligned. Completely aligned was having the top arm about quarter of inch from the stop(when it hits the side of the cylinder) Now when I run my bike the powervalve will not open. After 1/4 throttle no power. Has anyone found a trick to getting the arms to line up properly??? It worked fine for me 6 monthes ago but now I can't get it to work and I really wanna ride and stop wrenching!! Maybe this isnt powervalve related?? I dont know, I could use some help. Also with the powervalve supposedly stuck on close My bike seems to rev fine in nuetral. Why is that? shouldnt the powervalve need to open to rev out?
