Hi all. Trying to get thoughts on some things going on with my 2002 Honda Shadow 1100. I've noticed some minor backfiring while decelerating, and cylinder number one's spark plugs look like they have dry carbon on the electrodes, and the threads have a layer of oil. did a compression test and the compression is 155 psi for cylinder 1 and 150 for cylinder 2. Did a wet compression test and the pressure went up to 160 and 170 respectively. The numbers of the dry compression test are out of spec, the service manual states that the low end of compression is 157 ( 185 plus or minus 28). I have been reading that if the wet compression test makes your compression increase, it is likely your piston rings that are worn. Other than the mentioned "symptoms" the bike runs fine to me. No hard starting or idling. Do these specs warrant breaking the engine open and servicing the piston/rings/valves or should I try a carb cleaning first ( or something else)?? All thoughts are welcomed and appreciated. Thanks-
