well im new here and need some help with a build. ive got a 86 250r that i have rebuilt with hot rods crank, pro-lite .050, fatty, power core and i want to try the carb off my 86 cr500. should i break in the new motor with the stock carb or go with the 38mm from the start? if so what do you think would be a good start on jetting?
