Doing my first topend on the MC28 (with the help of a friend; big thanks to the site for the info) since it had pretty low compression (about 85-90psi in both cylinders). I thought that was wierd since its supposed to have about 8000km on the bike. Took some pics of the lower cylinder since thats how far we got today. How does it look?
left side of the lower cylinder
right side
top of piston (appears to have a bit of blowby; how does the jetting look?)
inside of the barrel (looks very good, no scratches; figure I didnt need to take the head off since it looks good)
