There is no JS 650.
650SX's are almost hated around here. I personally think they are fine for a first ski. Don't bother doing more than the <$100 and free mods. Save the mod money for your next ski. Keep the 650SX around for friends to ride.
Search here and PWC today, there was a guy that...
Ported 61X cylinder (didn't' specify the bore) and +5mm stroker crank.
Seeing that video is killing me. We've got to get our dyno working soon. We have a jig to allow us to bolt it to the back of the pump after you remove the reduction nozzle and tail cone, but it needs some machining so we are...
Awesome, thanks for posting that.
EDIT - Oh yeah, can you post the full dyno run info? I'd like to see the rpm vs hp results. Just curious on the power band.

If you open a picture at the bottom of the page the picture shows up at the top. You have to scroll up to see it, but the scroll makes the picture disappear. I have to click Open in new window to see attachments.

My NPX wetsuit is a kiteboarding wetsuit. I didn't realize that sport was big at all.
If I were promoting kiteboading I would emphasize the "green" aspect. No motors, no batteries' etc.

The Power Factor pipe has a inner and outer pipe at the stinger just like shown on page 1. The ID of the inside pipe is only 42mm. The ID of the outside pipe is 48mm. I used some pretty crappy calipers so I could be off by 1 mm.
I don't understand the fascination with the B-pipe. I was designed...
VERY COOL!! I noticed the exhaust ports are offset, I assume that means you are putting a 62T flange on the cylinders?
What's that crankshaft weigh? Any chance it will be available separately?

That is soooo awesome. I hope the show catches on and makes it to the states. Tightirash - hope they'd let you do your show in the wave pool, haha.
So John - does Lee let you win sometimes? J/K.
