My carb is not jetted right at all and I can't get jets right now but wanna ride... I have a keihin 28mm backup carb here with a 150 in it can I run it... it's a 250 main in my mikuni... with airbox lid off 3mil port work +4 timing and full fmf exhaust... would 150 be enough I have some jets for the keihin to do plug chops just wanna know if the 150 main is a good starting point

The 250 in the mikuni is to lean.
150 Should be in the ball park. But only a plug chop can give you your answer. Dont want to fry anything
