This week I pulled the primary, drained the oil, cleaned out my clutch baskets, installed new Raybestos clutch plates (they were soaked with oil), added 15% stiffer clutch springs, relocated my left foot peg and shortened it, adjusted my forks, and checked the plugs (which were about perfect color). Both cylinders running evenly. I'll add some more foam under the tank, check all the bolts - and I should be good for a few more laps. Zero degrees this weekend ! Maybe I'll wear my electric socks with 2 D batteries . . . ?
