Did a carb change over on Mikey Forrester's rotax this weekend. Got rid of the mikuni carb and put on a keihin 42mm pumper carb. Had to make a new manifold, with a new cable linkage, velocity stack, resize the reedcage holes from 5mm to 6mm and move the rear handle back to it's original place. Jetted and rejetted(to rich) then did some test cuts last night. Picked up .3's of a second over the old carb set up on the first test cut. Made about 3 more cuts and broke the chain. Fixed the chain and a few of the teeth we broke off, and then waited for more testing this morning. We tweaked the Lo and the High needles a bit and tried somemore test cuts. WOW! it came alive. Everything is dialed in.
Mikey, Melvin Lentz and myself are now planning to go to Eagle River, Wis. Feb.18, for a little preseason racing. Somemore of the Stihl Timbersport Series guys are supposed to be there. Just what we want....a little competition to compare to. Hope to meet Cliff Helsel too....should be a fun road trip.
