300x low RPMs and low mph, problem solved !!!
I love our 2011 Kawi 300x. The best ski we have ever owned. The only mods are an aftermarket steering system from Idiartec and a R&D SCOM.
I was hoping to get a few extra mph with the R&D SCOM, but the best I would get was a little over 68 mph. I read several postings (on greenhulk) how my rpms should be in the 7800's, but I was at 7610 rpm. I knew there was a problem, but didn't know what.
The guys at R&D tested my intercooler valve and it wouldn't hold any pressure (it was leaking). They popped on a new trick valve and it solve my problem. Now I'm at 70.9 mph (I'm heavy) and 7840 rpm. These valves are now available, contact R&D in Santa Fe Springs or your local R&D distributor.

Good Job - Glad R&D helped you get things sorted out !!!
PS - "stored" RPM is always different and a numerical value that is < a "live" RPM reading.

very correct ed ^ never take notice of stored rpm as its actually backward recorded, meaning if the speed is maxed out before max rpms are reached this is all that is recorded. wonder if the op actually did have a faulty bypass or bov in the first place. they arent something that ever give any trouble. my guess is coincidentally he has ridden again and got a differing max rpm reading..

So I installed a new R&D Adjustable Boost Control Valve. I picked up 230 rpm a couple mph top speed. If your down on power like I was, send your OEM valve to R&D to pressure test it. It's a 25.00 service (if leaking) that will apply towards the purchase of their new valve.

Sorry guys, I'm pretty jazzed about this and using a phone to do my postings. Thanks for the input.

Most just block that valve off, with a stock prop you should be seeing about 8000 rpm. That Idiartec steering is trick, how about a few pics of it?
