Eager to see your videos of this thing on some glass, OP DK

They're all great. You're not going to notice a mind blowing difference between the 1mm over 718 and the 84mm "max" bore in he 61x (appx 753cc) - The porting work on the cylinder and bottom end and proper jetting / pipe will be where all your power comes from, regardless of the 718 or 735 cc's...

Have done this same mod (RCJS SBN44 adapter or similar) to a few friends skis and it just transforms the ski from an unreliable turd to a reliable donkey. Nothing fancy, but at least the ski is now gonna run every time and pick up a little top end maybe. I did more 650SX riding this summer than...

Back to back results... no surprises really. Bottom end is the same (i.e. Just fast enough to barely balance, like 1mph, standing up and punching the throttle). Top end WOT for 5+ seconds is the same (I'm able to hit 47mph on both 38s and 44s) Mid range tho... 44s take the cake (and eat it too...

We need to start a GoFundMe to help E350 move out of his current communist home state so he can live in a state where freedom still exists so he might stop polluting every thread the almighty X(-H2O) with his political sniveling. Jet Skis

I'll throw my oem 44s back on this week so I can get as close to a back to back as I can. I swear they would pull outta the hole ever so slightly better than my 38s, i.e. launching outta a trough between wake waves on short notice or pulling out of a 360 spin with authority. I also wanna see if...

The motor is in the same realm - is this one you've used before or have experience with? Ye Olde factory pipe dyno charts - are these really the best charts we have to show the power of the mighty yamaha engine? The dyno chart for that motor from the manufacturer is below. Some other vendor...

Usually someone tracks miles on a phone in a dry pouch. We do a lot of river / tributary and lake fork exploring so we can cove chase - so we've done some 90 mile days (2+ refills). I think we've seen just about every piece of coast line at lake havasu from the dam to the sandbar as well as all...

I would disagree on the better bottom end. It's equal if not every so slightly worse IMO. Top end becomes very 'safe' feeling - but definitely loses the mid to WOT pull for sure. I was able to pull 47mph with 38s and keep it pinned WOT for 10+ seconds. I made the jump down primarily to get...

Here's a new AI mix. I used inspiration from this thread: https://www.x-h2o.com/threads/how-i-assembled-my-solas-pump-without-a-press.137372/ Basically asked chatGPT to create a rap song using the instructions. The inspiration for this song came from doing 3 (or more?) of these pump builds...

Recently I found out about A.I. music generators. All I can say is that they are way better than you could imagine already. I asked for some song ideas from my buddies and I'm putting together a "Beach Playlist" for jet ski sessions. If you're into hip hop - this one came out exceptionally...

A stock pipe vs a simple B-pipe will increase the decibel output of the ski by a non-zero amount, especially if the exhaust outlet were to come above waterline... I haven't heard a ski with a B-pipe that I would call quiet unless it's parked on the beach. Throw in some porting and it's now a...

I just want to rip up any body of water and not be told "no" because it's a 2 stroke and makes loud scary noises. I'm pretty far from being an environmental steward and EVs don't really do anything for me. Same reason I wanted an electric dirtbike like the Stark Varg - to be able to ride 'less...

I did a whole prospective analysis for an electric drivetrain back in college for our 1/2 scale formula race car. The power to weight ratio back then was good - with YASA and their axial flux motor leading the charge. YASA is now owned by Mercedes but the technology has only gotten better with...

Not dead yet. Just missed a deal yesterday for $7500 near Denver: 2x RN SJ's 1x SN SJ Trailer Not too bad, one of the RN and the SN looked a bit neglected but after you've worked on these things for a while there's only so many things that can be wrong. As FastGT says - pass the knowledge and...

Did you try stock jetting first? I've run my ported 760 WFO for 10+ seconds with the same jetting at havasu and ruedi without issues. Is it a bit rich at ruedi? Yea a tad, but I usually only need to compensate with 1/2 turn on the highs and 1/8 or so on the lows. If you're not having luck with...

Just the gasket. No sealant needed anywhere on the SBN carbs.

Cheap Hoes often come with unwanted side effects tho, like a burning bilge area

Prices overall in the high rockies are starting to trend down. I'd say, speculatively around 25% or more from peak covid pricing. Still not back to pre 2019 prices and we likely never will be with the change in the value of a dollar. One thing is for sure, the majority of listing's are no longer...
