Why would a cylinder have high compression?
High compression in a cylinder usually means there is liquid oil and/or high carbon deposit in the combustion chamber displacing room for air. The air gets more compressed (because the combustion chamber is essentially smaller) and the pressure reads high.
What’s the best cylinder compression for an outboard?
However, four cycle engine cylinder compression should still be within 10% cylinder-to-cylinder. Older two cycle outboards, especially low horsepower, can run fine around 60 psi however above 90 psi is optimal. Four stroke/cycle engines produce much higher compression. The main thing to check is the difference between cylinder compression.
What should the compression be on a Honda XR650R?
Honda XR650R is 87 PSI with decompressor applied and 160 PSI with decompressor not applied. It jumps all over the place so check your shop manual before you rip the top end off thinking the compression is too low.
Can a motorcycle engine run with less compression?
Yes, an engine can run with lower compression, but it will run very poorly. I’ve seen old, big, multi-cylinder outboards run with as little as 65 PSI and some lawnmowers run even less. However, for motorcycle engines 100 PSI is really on deaths doorway.
