Hello All,
Once again, I'm rebuilding a Yamaha 700 MM. The current version works well enough to be competitive with most new mountain sleds. Progress to date includes the following mods. 151/15/2.3 Camo track, coated PSI triple pipes, MPI head c/w 19 cc domes, rolled chain case, roller driven, extravert 9 tooth drivers, trick primary, Boss high top seat, Diamond S fabric hood, AC skid, 20/42 gears, ATACC compensator, MPI remote fuel screw adjusters, Simmons skis. The new version will have a welded crank, 162 MPI tunnel, 162/16/2.3 Camo track, 30 hp Boss Noss, all available MPI lightweight front end parts. I want to increase traction, increase hp to 160 on the bottle at 10,000 ft and reduce weight to 450 lbs. My only experience with Noss has been to endure repeated beatings in Cooke City, MT by a bottle fed Rev. Will appreciate all advice. Parts arrive mid June. Construction starts then. I will keep a photo journal and post.
