I cut a 2" x 8 3/4" piece of cardboard and blocked off a portion of my radiator. My running temperature went from 162 degrees to 188 degrees. I'm OK with that. I'll make a more permanent block off with a 1/8" thick piece of neoprene rubber. My bike is pulling 35 lbs. of oil pressure at 7K R.P.M. I hit 100 M.P.H. today running 15/42 gearing and 110 main jets at 12K R.P.M.. I have not shimmed the jet needles and doubt I will.
Happy day - you can tell by the bugs in my teeth.
