I need a refresher course.....

Yeah I love my 760. It was ported by Paul at LPW, has an msd enhancer, dual 44's, b mod pipe, ada girdled head, and it rips. I'll be puttin the lightened flywheel on before the season starts so that should help it rip even more. You wont be disappointed.

Good news!

Got a link to the 760?

Yes, 760's were designed for the GP waverunners and Waveblaster II and Yamaha did change the compression ratio between the front and rear cylinder, 6.4 on the front and 6.2 on the rear if I'm remembering right. I've have been able to set up freestlye motors with the right combination of parts, ignition curve and carb jetting and have run 200 lbs on 93 pump with no problems with all of the 64X, 62T and the 61X cylinders.
P.S. This of course is on Superjets...I do have 1 Waveblaster running 210 on pump and so far no problems as of yet!

So you can go 200psi and pump gas on any set up as long as it is not for WOT?
