What was the reasoning for the timing retard on the rear cylinder when the 650/701 motors in couches never ran that? How needed is it on couches? I want to build a 760 for my raider. I have a full 760 ignition setup lying around to use. Do I grind the retarding spot off the flywheel, or is it a...

When I built my superjet, it was a all new combo and I went with the most recommended carb setup via the carb database list because carbs are not my strong point lol. Dual 44's on a modded 760, everyone likes 125L and 115H and tune from there. Sure enough, the ski started right up, idled good...

I need some new reed gaskets for the vforce 3's in my superjet. Their website is broken so I can't lookup what part number I need. Anyone know?

The website seems to be down, and they haven't answered me on facebook. Any way to contact them? I have a internal fill gas tank in my superjet that needs a new o-ring for the filler.

Ran my new to me combo a bit last summer then pulled it all apart over the winter to make some changes. Noticed from the gasket imprint the large difference in gasket opening vs the pipes openings. Should I open the pipe to match the gasket or leave it alone?

So, I've always wondered....the oem bilge goes up to a block at the top of the engine compartment, before going down to the actual pickup. Why is that? Why wouldn't the hose just go strait to the pickup from the pump?

I was recently diaging a problem with a ski and my buddy pointed out the rubber gasket in the pump area was wrong [#5 on the chart]. I had used the large hole gasket instead of the small hole which is used on 44's. I had never know about the differences, so I pulled apart the set of 38's on my...

-First up is a set of oem SBN 44's from a 760. They are setup on a protec intake manifold and are jetted for a 701 w/b pipe in a superjet. $250 shipped in the lower 48. -Second is a set of ADA 33cc domes for 81mm bore [701's]. Would prefer to trade them for high comp 760 domes, will sell for...

Last winter, I sold my square nose and got a round nose. I kept the bored [84mm] and ported cylinder and modified head to put on the new ski. Old ski was single carb, new ski is dual 44's. Also went from a protec pipe to a limited B pipe. I did 125L and 115H jets. New setup rips great... The...

I have to put a steering cable into this RN I aquired. I have the parts on the pic, just not sure how to mount them. The plastic collar won't close around any of the reduced diameter metal spots as far as I can tell. Which spot does it go? Does the washer go before or after the plastic ring? Am...

I installed one of these things in my last ski but it was years ago. Got a new to me ski and am putting one in it as well. Thing is, the instructions are not what I remember. They show the wire from the start/stop switch going to two spots on the solenoid. I only remember it going to the small...

So I'm putting together a RN. It came as a hull with all the parts in boxes. My buddy had pulled everything for his rickter build, then bought and stripped a cheap VXR for its drivetrain and put it in this RN for his lady to ride. Fast forward to now, everything was pulled except the pump. He...

I was replacing the orings on my buddies square nose last night. The domes were marked YA7631L. I'm guessing this means yamaha 760 cylinder at 31cc? According to ada thats about 230lbs of compression?!?!? This thing has ran 91 octane for the last 5 years. It has some porting, but I've only seen...

Ok, its not a standup, but I figured some peeps on here have messed with these before. wave venture 760. It only has one metal nipple on the exhaust pipe, and one rubber where the coupler is. Head has two outlets. Ski only has one pisser. Does one outlet on the head go directly to the pisser and...

My raider has had a running issue after heating up that I've narrowed down to most likely the stator. So went to put a spare on last night, and when I pulled the cover I got a lot of oil that came out. Between that and the random tiny washer I found stuck to the inside of the flywheel, I feel...

So I read the instructions I found online, and it mentions putting the top two middle bolts in first but doesn't mention anything about tightening them...Am I really only tightening 6 bolts and leaving those top two middle ones loose? I can't find any way to turn and tigheten them once the...

I'm using an oem 760 intake manifold. I have a protec sitting here too so I know I'm using the correct adapters in the vforces for the oem manifold, yet it has this large mismatch thats driving me nuts. Can this be ported to match or should I leave it alone?

Putting together this round nose from boxes of parts. Have two flywheels. Identical in every way except the magnets. Anyone know why? Need to use one of them.

Is there any performance benefit to running a protec manifold over the oem manifold on a 760? I noticed the ports are different shaped openings where it meets with the block otherwise they are the same it seems.

Why can't I find the part number for Riken piston ring sets for an 84mm bore? It's driving me crazy.
