Folks, before I took the engine apart, balancer was at 3 BTDC when the cam dots lined up. R&R cyl head, got the cams back to dot-to-dot, but now when i roll the motor over, the dots line up at near 10 BTDC.

Please tell me the chain tensioner has to be pumped up to take the slack out of the chain, and it retreats a few degrees.

Otherwise I'm stumped. 5 degrees inst jumping a tooth. ( it couldnt have jumped, I had the chain lashed to the gear all along. )
