Spent the winter studying up and collecting parts. I think I’m going to end up with a decent rec ski to compliment the mint 96 XP I wound up with. I put my UMI on this weekend. Felt kind of bad pulling it out of the blister pack.

Did you ever install the Yamaha trim?

What size Protaper bars have people found to be most comfortable with UMI steering on these hulls?

Do you think the carbs I have are probably "too much" for what little else is modded on the ski?

Here is a performance question I've been kicking around. I'd appreciate any input. I ran those aftermarket carbs and intake for the summer. Never got them tuned perfectly. They always seemed to run rich. Granted I only had it out at the very end of the summer and only rode it a few times. It...

Very nice dude! I'm in the classic car restoration industry and I know how hard it is to find good upholstery guys

That's fairly low compression. But it's even. Another important test to do is a leakage test. It's more involved than a compression test, however if your motor isn't air tight it's not going to run right, especially with the added resistance of being in water. How well does it run out of water...

Also, does anybody have any knowledge on the quality of aftermarket RAVE parts?

I see. So I'll replace both housings and slides. I still have at least a couple more weeks of riding left, hopefully. If it stops raining. Sounds like I need to do a leak test also. Can my pop-off gauge handle that?

So I noticed my rave valves were leaking around the base gaskets. Earlier this summer I replaced the caps and bellows with oem parts but didnt remove the bodies. While disassembling the valves to replace the base gaskets I found that both of the bellows had slipped off the plastic caps and...

I've been riding the SPX for a couple weeks now. The thing rips! My final jetting wound up being pilot 125 main 120 N&S 2.0 pop off 25 Since I had time while it was down, I went through the ski and fixed a few other issues I'm glad I found. Replaced fuel lines, the rotary valve was off one...

After more research, I'm going to stick with a wet pipe for this season. The tool truck finally came by the shop with my new compression tester. I had originally been using a cheap Amazon special. With the new tester, my averaged numbers are 170psi mag 168psi pto with the intake manifold off...

I would absolutely buy in to that.

So what all will be involved with switching to that pipe? What else will have to be changed and or tuned?

Ok cool. Last question for now, I'm going to change out my exhaust pipe and water box. Any recommendations on the water box? I'm eyeballing a certain Neptune pipe that's currently for sale...

Ok, where should my pop off be?

I tried it when I first cleaned the carbs. The setup they had was dumping fuel and immediately fouling the spark plugs. That was with 2.0 n&s. The 1.5 is way too lean

Took the intake manifold off to check for a crack. Once I got it in better lighting I was relieved to see that the suspected crack is just CNC paths. You can see them in a couple other spots on it too. I mic'd my carbs, they're 45mm on the intake side. The intake plenums are 47 at their widest...

I'll mic them tonight. Sounds like I'm getting closer to some initial settings, barring a horrendous vacuum leak, or truly low compression. Tool truck comes this week with a new compression tester for me. I used a cheap one for the test

I noticed that too when I pulled the carbs. There isn't anything continuing down the sides of the manifold, but I'm going to pull it and check it. Hope I can come across one if I need a new one... Here's some pictures of the carbs. @Matt Braley can you give me any info on these? They're stock...
