Its hard because I hate dealing with wolf creek racing for jets, the guys is an ass hole. You would think you would be nicer to someone who is giving you money for relatively little work.

I cant afford a weber 50 DC SP unfortunately but thats what I need

I also run about 4.5psi of fuel pressure for the mikuni, it seems to like it.

they do make a mikuni 50PHH but you can only buy them in pairs

you should be able to get proper afr's with your existing carb. to richen up the top end try an emulsion tube designed to add more fuel at a higher rpm. or in the mean time try a smaller air corrector jet
