Leaking cylinder base gasket : replace ? By Kaveman (Read 1,504 times)

[Kaveman]

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.

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.

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 ?

One more quick question.looking at the side of the flywheel (going clokcwise) is a line then a T F and another line . TDC is the line before the T ?

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 !
