Set up.

e50, Polini, Matched.

Modified estrol.

15mm Bing, Polini Reeds..

Currently 88 jet, Clip second from the top.

I have been slowly working my way down from a 96. The 90 felt great on the top end, but was oviously rich on the idle. Went down to an 88 and it idles beautifully, but isn't getting enough gas on the top end (past 3/4 throttle).

So, I am thinking I have a small air leak somewhere. Any ideas?

Also! Having never or even ridden a polini before but doing all appropriate research I am shocked by how torqey this engine is.

Started with 14x45 gearing (city bike - way too extreme), went to a 16x45 felt like it was still pulling too hard, now I am at 18x45, and it still have amazing lowend with some great top end, but I think I could go steeper and still have decent lowend.

What're other people riding with the polini?
