Starting to notice moisture in cylinders. The motor will fire and runs well however after running I need to pull plugs and spray fuel into cylinders to clear moisture. What gaskets should I replace?

In all probability, in order for water traces to gain access to both cylinders, the head gasket would be failing at the center area, between cylinders.
Remove the cylinder head, clean the surfaces of the head and crankcase. Install a new head gasket and torque to factory specifications (whatever they are) and in the sequence as follows where each number is a head bolt:
9...10
5.....6
1.....2
4.....3
8.....7Last edited by Joe Reeves; 07-09-2019, 05:09 PM.
