I don't think that the stock exhaust is gonna get it done.

The gay trike also only has one wheel in the front making it stupid light in the front and shitty handling.

If you want a quad to hit 90mph, you must first gear it to do that. If you can hit 7500 rpm, run 21" rear tire, a 15/40 sprocket will hit 90mph on a lt500r. Next issue is having the power to attaching hit 7500rpm in 5th gear.

You're probably gonna need a pipe that pulls a few more rpms on the top end.

Other members can chime in but didnt the FMF fall off around 6k during dyno tests?

Allcools stock 500 with gearing, a Qv1 pipe, and tuning went around 103 - in florida.

alkyzilla has a qv1 pipe for sale for a really good price.

to set the PV is 1 full turn CCW.
