Thanks guys for the direction.......I'm definitly not going to go up to a 750, at least not right now until I do some monkey-work with the current set up.
So......just to check with what you guys have suggested......
I'm going to pull the secondary bowl off and see what size jets he put in. #2 ---- is there a size stamped on the squirter to verify the size so I can go up on???? If so I'll----
1.) Increase my jet sizes in the secondary by 2
2.) Increase my squirter size in the secondary by at least 1-2 sizes
****From what info you guys have given me (which is appreciated!!!) that should be a good start to see if I can correct my hesitation/lean out condition at W.O.T.???
--- And I should be O.K with my primary set-up (For now) as it seems to run excellent until the secondaries come into play on heavy pedal.
