Super Jet First SJ power mods

[firstski650]

Last month I got a '90 650 superjet for $700 off craigslist. It runs perfect but I feel like a little more power now. So I wanted to know what all I could put in my ski to give me a little more get up and go power and maybe a little higher top speed.
Thanks!

Sell the 650 motor and buy a 701 motor. It'll drop right in and really is the most cost-effective way to get more power.

Purchase a 701 for it, then mod that up!
