Surfriding Hx compression help

[Freerider912]

Hello my name is Brandon and I have a 96 seadoo hx that I am doin some work to and just looking for a bit of advice for dome recommendations. It's still a 720 and the mods so far are: k&n filters, r&d intake manifold, jetenetics light weight charging fkyweel, an factory pipe. I want to stay on pump gas but want the most I can get while staying on it. Just wondering what a good compression range is for this ski.

Honestly, you will never make that motor last very long with the factory pipe if you run pump gas.... I know for our sport spec HXs we are limited to ~165psi compression. But, the factory pipe on the 720 is a very sensitive combination and on stock compression I would still recommend that you go higher than 93 octane....
