650/X-2 prop help

[flyin-bryan]

I need some help finding out what pitch to run. I have a 91 650 sx, west coast pipe, 44mm carb, 160psi and the stock prop. I want to have a low end hit like riding freestyle what prop should i go with.... Thanks

Find a straight 15 or 13-16, 14-17, 8-16, 9-17, or a Solas A. Everything else will overload the engine without a custom repitch.

A 9/17 SKAT is as good as it gets without going large hub, cutback and using a R&D or TBM stuffer.

A cut-back SX-R big hub swirl prop, re-pitched to 9/17 as good as I've seen in a stock cylinder ski. You may want a bit more compression, say 180psi and a lightened flywheel.
