Low Compression On A Cyclinder, Should I Replace Piston Rings?
Did a compression test on my bike.
Bike runs. It sounds like my cylinder may be misfiring but I'm not sure. Sending my carbs to be cleaned today.
Compression test after bike warmed up:
Cylinder #1 (Left side when sitting on bike)
Dry: 145 psi
Wet: 205 psi
Cylinder #2:
Dry: 110 psi
Wet: 195 psi
Valves just adjusted and are in spec.
I don't have a leak down tester, I may consider buying one, but not sure if a leak down test could tell me much more than the compression test.
Wondering if there is anything else I should check. If I do end up needing to replace piston rings, how many days should I reserve if I worked all day on getting the rings on? I've never torn down an engine, closest thing is doing valve adjustments myself.
Does this look like a probable piston rings replacement scenario?
I've heard of those products like Rislone Compression Repair additives, but do they actually work? Could this be a temporary solution (help for 10,000 mi)
Can I replace piston rings with the engine still on the bike?
