HIDEF

i have been searching and searching everywhere and cant find the info i need so maybe someone here can help me out. im not sure what size domes or pistons the bike has but i noticed that the right side (sitting on bike) was smoking just a little bit more than the other so i did a compression test just for piece of mind and i got approx 164-166 on the left and 150-152 on the right. i know that maybe 1-3 psi is ok but is 10 to 15 way to much of a difference. im at sea level. im running 93 octane @ 32:1 and according to the plugs im a little rich if any of that makes a difference. any input on this would be much appreciated.

I just want to say hello to everybody here at the B HQ and thanks to all the ppl that put there time in to helping others and making all these pinned topics with pics and diagrams. i joined the forum about two weeks ago with a million question about my new to me shee and i must say that there is a answer for everything here. Thanks. and sorry if i posted in the wrong place. Atleast its not another oil thread
