Guys, keep in mind Hulk Jr weighs 160 lbs. A heavier rider wont encounter as much bounce

It does have the RIVA intake grate on it. The porpoising is very weird on this ski. Full tank of gas and it was rock solid with no shimming of the ride plate. The more fuel it burned, the more it bounced. I ended up putting two shims in the rear bolts of the ride plate and it fixed the problem as long as I sat straight up on the seat. If I stretched out on the seat it would start bouncing again.

At what speeds did it start wanting to bounce?

That’s really awesome! Did this FX have the intake grate on it as well? Have one lying around but haven’t gotten around to installing it in my ‘21FX… Also, does she stay pretty planted or did you notice any purposing? Thanks Greg!

Does the dash display accurate speed? Did it show speed over 70?

Dash was displaying 83. It is very accurate.

Great work! What RPM were you turning?

No digital tachometer on it yet. Looked to be around 8700 according to the dash. There is definitely room for improvement there and I'll be using a digital tachometer to get the RPM higher soon.

I just finished installing the complete RIVA Stage 2 kit, intake manifold upgrade, and RIVA sponsons on a brand new FX SVHO with less than an hour on it. The tune used is the MaptunerX Stage 2 9200 AGR. The best speed I got was 83.1 mph and numerous runs at 82.X mph. The sponsons are well worth the upgrade and greatly improve the handling of the ski. I'm impressed for it being such a big ski!
