Mikuni setup

[Ironheadmike]

Does anybody know of a good and tested carb setup for a Mikuni hsr45 that on a 113in engine ? I found one for a 127in at 0 sea level . What would be the changes I would have to make for my engine at sea levels around 1000-2000 ? Thanks for your time .

Easy answer is no.  Carbs are signal operated so what kind of combo really matters. I have a 127 that I played with a S&S and Mik. I was very surprised on the small jets both carbs wanted for engine size. A stronger signal pulled on the jets hard.  I would suggest putting something in there close and fine tune to your liking.

I'm looking for a starting point for the jet sizes .
