HP or the XP ?
Work pretty good on the E85 ?
Did you have to re-calibrate the Carb after you got it?
Did you get any noticeable power increase?

XP - The thing was perfect out of the box, did not have touch a thing other than idle and float levels.

Just did a back to back against race gas and my tricked 850 and picked up 24 hp..

Awesome carb

RacerHog

Wow... Thats a good jump....

Torque numbers went up more also, I think most of the bump came from the e-85.

The flat tappet cam I'm using has 282 @ .050 duration, and with this carb we were able to get a clean idle at 950 rpm.

I've heard the gas carbs need to be jetted but mine was on the money.

RacerHog

Stout Cam for @ .050.... Compression must be good?... 14-15.0.1..

Iowan

12.5, not a new build just converted to e-85.

I took out ten degrees of duration Bob, I thought it was mild. Hahahaha

RacerHog

Auhhhh,,, I see...
