What with all this talk about jets, i think we forgot to answer the original question

Quote:
Has any one put on the Short Slash Cut pipes onto a Speedmaster? If yes what have you experiences been with these pipes and what else need to be done, like tuning and so on.
Yes. No re-jetting, but adjust the air screws on the carburettors to avoid popping on decelleration. Three turns out worked for me.
