750sxi coffmans rocket mod pipe jetting

[sleeper sx]

Running dual mikuni 44's, jetting 107.5 main, 120 pilot, 2.3 seats, 115 gram springs, should I be ok? 150 compression, leak down was good , I put new gaskets and seals on crank. Bottom end snap is weak, topend is good once I can unload prop off a wake, to wot it lags big time then finally opens up. Any recommendations? Need advice guys, thanks.

Whats your prop ? It should be a skat 9-17

I would try richening the topend a quarter turn left on both high speed adjustments , can you pull your plugs and post a pic?


If its worse go back to the adjustment were you were and go the other way or leaner
