SOLVED! I rejetted the carb with these settings: 75 pilots 135 Mains 1.5 N/S w/65gr silver spring 1 Screen on each Flame Arrestor (down from 2). And it rocks! From what I've gathered the popoff is going to change from person to person because of altitude/air pressure. I originally tried...

Thanks for the replies. I'm sorry I forgot to mention that I am running dual cooling as well (2 into the exhaust manifold & 2 out of the head) From what I've read on other forums, I think that YAMAHA set up the carbs like this in the wave raider because of overheating the the rear cylinder...

Ok so I've got a tuning/jetting nightmare on my hands. I put a 62t/62t into my square nose from a 95 Wave Raider. Running dual 38mm carbs, added some boyesen reeds, brand new factory B Pipe, & I milled the stock head down (186psi in each cyl.) From the factory site I've got the carb jetting...

Ok so I determined that I needed to do a leak down test. It was much easier than I had thought it would be. ( I used this as a guide: http://www.x-h2o.com/threads/1303-Pressure-Test/page4 ) and I found one of the bottom crankcase bolts were loose and pissing out fuel & oil. I tightened it up and...

Ok so I've been working on my ski all winter getting it ready for summer and I've run into an issue. Here's what I've done to it and what's going on: It's a '92 SN and I've spent 3 months re-shaping the nose, tray & footholds. I sold the 650 and put a 62t motor in it from a wave raider. (Note I...

Watch out. I had a js550 that would run out of the water but could not get it going once it was in the water. Took me forever to find the 1" hole in the bottom/side of the crankcase. (Previous owner had dropped a nut inside and the crank brought it around and punched a hole out the side.) i'd...

Hey guys, I'm just finishing up my ski and before I laid up the glass in the tray I ran dual 3/8" cooling lines. I'm now stuck as I don't know where to tap the pump for the 2nd line. Both lines come out on the left hand side (where the original was). I have a '92 Superjet and the only options I...

I'm in the process of re-building my '92 square nose SJ. I'm turning it from a square to round nose, widening the tray, and adding my own custom footholds. After reading up on some other builds the common theme was 2 layers of 12oz biaxial fiberglass and one thinner layer of 6oz e-glass all...

I had the same thing going on with my 650 SN but it built up more gradually. I would take it out and randomly after riding it wouldn't start again. I could wait 10 min and it would be fine again. It started getting more consistent and i could only run the motor for a few min, it would die and...

I went for it! $900 for the 701 Wave Raider, great shape. I've taken it out twice now and it runs great. Now I've got to work on parting it out and putting the 701 in my superjet. I'll be posting in the classifieds soon if anyone needs parts.

Ok so to clarify I'm not going to put my 650 in the wave raider. If I buy it I'll part it out and sell my engine separately. #1 Is this still a good deal (701) for $900? Basically I'm cheap, will I make my money back? #2 should I wait for another 760? Or will the jump in power from the 650 to...

Turns out the engine was a 701. Going to wait for something closer or cheaper. I assumed all the wave raiders were 760's, I'm glad I checked before I left.

Ya so the guy isn't sure what size engine is in it. Waiting to hear back if its a 701 or 760. If i do get it I'll just part it out, I don't like getting burned and I try not to burn other people.

Hey guys I have a 650 square nose and I want to upgrade my engine. I've found a wave raider 760 (rebuilt and bored out) running great for $900. The problem is my wife doesn't want me to spend the $$$. Would I make enough off of selling my 650 engine and parting out the rest of the wave raider to...

My 92' Superjet. Picked it up a couple years ago for $400. Have about another $400 into it now but its running strong. Just painted it this summer and she's looking great. Paint job was inspired by someone with a similar design. Hopefully this winter I can get some Yamaha decals, footholds, and...
