I'll fire it up when I get home. Last night, it probably cooled off between the time I tested it and when I cleaned up everything before I rode it. Maybe 1 1/2 to 2 hours. When I tested it, only ran it for about 2 or 3 minutes. Check top of pistons for what? Looked in there before I installed new plugs, yep, piston tops were in there. Only thing I can think of is maybe some contaminant was causing a shim bucket to stick, I dunno.
