My scooter is once again running after being torn down most of the week. The cylinder base gasket (one inbetween the cylinder assy and crankcase) is leaking. Do I replace now or try oil stop leak stuff ? 2 local shops have the gasket that would be needed. It's not drip drip drip but anoying none the less. Any suggestions would be much appreciated. Bill C.

Have you tried re-torqueing it down a little, you mentioned you are thinking of changing the cam again so if it is just a little drip and re-torqueing doesn't stop and you are going to put in the cam Soon then I would wait and do both at the same time. Alleyoop

The head bolts need to be torqued to 15 ft lbs in a criss-cross pattern

I'll try the torque wrench option first. I may still run the a9 cam to see what performace upgrade if any is happening . Would a 59mm cylinder upgrade help ? Bill C.

Update : I torqued down the head nuts as recomended . Was 18 ft/lbs too much ? I also adjusted the valve gap space on the rocker arm assembly . It was well over .007 before I did the adjustments to .005. The rocker arms were a tad bit loose ( most likely reason for the chatter I was getting). Tomorrow will be the big test. Im going to ride to a near by town and back and will be checking my spark plug incase I need to adjust the carb. The head nuts did need the adjustment aswell. Now if only the weather would be more cooperative ! Bill C.
