Why don't you drop down to a 185-190 main and put it back on the dyno.

The main is not to high I have had her with a 190 and 195 main and both peaked above 14.1 air/fuel ratio signifying a lean condition. actually that is stoich but with Michigan weather its better to be safe cause of temperature differences.

However I have now put a 195 and a clip richer on the needle.

Damn I wish I could post the graphs for you...must try photobucket...

I just wanted to know if the hp numbers are comparable to what others are getting

Sound a little high to me, and quite a few people have posted them on another site...also, the jetting sounds pretty rich compared to what others with similar mods have...

I don't have a hard copy of the dyno run, but with the LTE Racing Exaust System...

Peak Hp was right at the 44 mark

Main jet is either a 210, or 220, can't reacall ezactly.

It is starting easy, and has no noticable hesitation. It was actually pulling a piped YZF 450 durring the little local tuff truck/ quad war race!

What is the name of the place that dyno'd your quad?

The main dyno that it was run at was LTE Racing's dyno jet. The numbers on my quads have also been higher on the mobile units at both Sand Mt, and Dune fest. Actually the mobile ones seem to show about 2-3hp more than LTE's.

Your only 3hp behind Jon, I wouldn't be upset about that. Send me the graphs and I'll post it for you.
