Just spent 10 hours doing Dyno runs, went from 38 horsepower to 102. 10mm stroke, 77mm bore, 26cc domes, 185 compression, 35 pwk, 200 deg exhaust timing, 12 degree timing advance, DEG needle 3rd clip, 50 pilot, 130 main Every time I lowered the main jet it made more power, ended up at 1210 egt with 130, didn't have anything smaller to try, spent 10 hours getting this far. Crazy how small of Jets these are Sent from my Moto Z (2) using Tapatalk
