on my 86 250R I ran 32-1 r-50 klotz on hot day with stock exhaust and the plug color is good no problems. Now I tried my PSI racing hi rev pipe and a fmf turbine core muffler. I messed with it tonite, switched out the stock 42 slow jet with a 48 and the stock main from a 142 to a 152 and it seemed lean it wouldnt idle and no smoke at all then I bumped up to a 52 slow and a 158 main. Now I got a good idle I think I need to go down with the clip yet but it dont smoke at all after 3/4 throttle and it kinda sputters Plus its 30 deg here too.'m at sea level does that jetting sound close?
