I would have to go back through the article i wrote to say how high but 195 would seem about right. I cant remember how high it revved but it didn't mind it that's for sure. I have a friend who is running the stock 760 exhaust on his free ride ski and it works really well

The 760 exhaust is actually quite effective. Riva faced significant challenges in developing a better exhaust for the 760, and while they did produce an alternative, it doesn’t offer much improvement over the stock system. On a separate note, when it comes to triple-cylinder engines, Yamaha’s...

Heck I dont know that one as I never really use a stock pipe. but its hard to know as its not a tuned system. I would guess about 6900 but its only a guess

Awesome. I will get right onto to it soon. im busy building a new race ski for our nationals in march 21. its a 760 ported cases and cylinder. Also using the template as well

Hey Storbeck. It’s measured from the top of the cylinder. I normally run my cylinders with a zero top deck to get my squish right. So I will machine the top of the cylinder down. Normally the cylidner is about .7-.5 mm positive deck so the piston is sitting just below the top of the deck. The...

Yes they are pretty the same engine in regards to the long block. Other than bore size. The std porting is different but the end result should be the same in timing. Just be careful on exhaust port width. As 65% of an 84 mm bore is a a lot more on an 81mm bore

Here is the porting template you can down load and 3d print for your 84mm yamaha, 195 exhaust port duration on a .7 dech height yamaha engine. Your welcome https://www.waxracingproducts.com/pages/exhaust-port-template

Im a jbweld guy myself and i heat the cases up to mke it flow well. your idea is not something i have thought of before but i do like it. I may give that a go as well

Yes its a stock height one. I prefer the lowered myself in the surf and of course its appearance. But in racing the stock height is a better solution.

In Australia, we have an 800cc class that adheres to the principles of the old Limited rules. However, this isn’t a tech-focused class, so the engine must retain an externally OEM appearance, specifically regarding the cases and cylinder. This creates a unique and exciting opportunity to explore...

No they are about 1 week away, but we will make a big announcement. Thanks

We have these and file and were going to make them but it just turned out not worth it. would have been cool but oh well

yes at this stage its just the steer nozzle. we are working on a lot of new pump parts at the moment

A longer nozzle on a jet ski enhances handling, stability, and performance. It improves steering precision, making your ski more responsive and controlled at high speeds. The added stability helps it track straighter, giving you confidence in rough water and smooth turns. Performance-wise, a...

Thanks, Yeah im a big carb guy and when you are in the air and headed at the water with big carbs you know water is going to get in. its such a pain so i spent a lot if thought redesigning it. Nothing like the big carb hit and the stock filter water dispersion

The Evolution of Airbox Systems for Mikuni Carbs Back in 2002, I decided to upgrade my ski with a pair of 44mm Mikuni carburetors. The additional power and improved throttle response were phenomenal, but the setup had a significant drawback: water ingestion. This challenge prompted me to develop...
