As far as the clutch i'm going to wad the wt. to it & hope for the best till I get the 44's dialed in. Then I'll try the heelclicker kit thats on the shelf.
I installed the M10 last feb. & got about 1200mi. on it, the M10 is likely the best mod I have ever done to any sled.

Sorry this is the best I can do. I took these before assembly this afternoon. The cyl's came from another mxz that I returned to stock & sold. It needed help, ports were not equal in vol., squish too tight, compression too high.

Was that stock cyl's that had port and squish problems, or someones handy work that came in to the shop?

Do you use a program like "Port 2000" for your port specs?

MXZ900 did you have to do anything to the crank to beef it up?

Nothing to the crank, but the upper half of the case needs to be machined to accept the larger dia. of the new cyls.
