45 Mikuni on a 117"

[BigT00]

Mike,
I am thinking of trying my 45 Mikuni on my new 117" build to save a little cash. It is currently jetted for my 103". Would you happen to have any ball park recommendations on jets sizes for a
117" motor? I know there are a lot of variables in jetting but would like to get it semi-close so I get get the bike started and heat cycled upon 1st start up. (Great website!!!) Tom

Jet size varies a lot depnding on type of heads, exhaust and cams. Typically, 45 jetting has been from 175-190. I would tend to err to the rich side so would start with the 190.
Thanks, Mike
