I freshened up my ski, and as part of that installed a flow control valve. It is the only thing I actually changed, apart from the prop to a 9-15 hooker. I did strip the engine, but just to change the crank seaks. Now after running for 15 or so mins it feels like it is overheating, and the...

Jeff Having a bit of trouble getting in touch with you. Have tried emailing and phoning but couldn't get through. Just trying to work out when my diablo hood kit shipped, and whether you have a tracking number. It hasn't arrived yet and I need to get an idea for when I can get the ski...

I just bought some expanded polystyrene (EPS) for my refoam job; similar to what new household appliances are packed in. Will this be ok, or should I use extruded polystyrene (XPS). The EPS has some air gaps around the 'beads' of polystyrene that I guess could hold water. Is this an issue? I...

I have just noticed there is a big gap between the impeller and the housing, and my ski feels like its calvitating (or just not hooking up). I think it has been like this for a while, but I have just noticed it when I added a b pipe, ADA head and epic ignition. I'm going to get a new...

So I've been having an intermittent misfire, and the ski has died a few times (no spark). Anyway to cut a long story short I worked out yesterday it is the stop button on the stop start switch. I took the switch to bits and it all looked ok (no corrosion) so I gave it a clean, sprayed it with...

What is the best way to install the Bendix? In the past I've just installed it dry (just grease on the bushes) and this has worked ok, but this time it feels a little bit sticky when you actuate it. What (if anything) should I lubricate the bendix with? Or should I degrease, wash and dry it...

Ok first off 96 SJ with a bog standard engine. Last weekend I was riding in the surf when the ski started to misfire really bad. I noticed when starting it I would get electric shocked through the throttle lever. I thought it looked like a damaged ignition lead as one of mine was broken (had...

I have unsucessfully tried to search for this, it must be out there but I can't find it :sad6: What is the difference between a straight and curved umi throttle? Which would suit general freestyle / surf riding / wave jumping? Cheers, Andrew

Hi everyone, I have a round nose Superjet. When it sits in the water it leans over to one side, like it isn't balanced right. It also is easier to turn left than right, right feels far less stable. Is this a common problem, and how do you guys balance your skis? I was planning to balance it...
