Kawasaki foam is much better than what’s in a super jet. You will need to peel up the floor and let the foam dry for a while. Then everything can be bonded back together with epoxy.
Try them out, they will need to be a lot better in order make a difference you can actually feel. Then you will know the credibility of everyone that wants to sell you a modified carb.
Back in 1992, mod class 550s were typically ported and propped for much higher rpm so shortening the pipe was necessary. Leave the pipe long for now and learn how to tune the carb. Then learn how to tune the impeller. I do not recommend turning up the RPM on a 550 anymore since they become so...
There is no way to keep water from pouring in during a sub. The best way to deal with it is a bilge pump. An OEM single carb 750 flame arrestor works best when there is a lot of water in the hull. I clamp an elbow to them and turn it toward the engine.
This is why I say use only TCW-3 if it will work. All watercraft engines are very susceptible to rust. Petroleum and butene in cheap oil are the ingredients that repel water but they aren't the best high temperature lubricants. Try Maxima Super M, its basically a higher temp oil with lots of...
One thing that is ultra important that few riders even realize. “How do you know if the pump load is correct?” Answer that and 90% of problems will vanish.
The 650sx is too slippery to turn flat and you have to slow down more to get it on an edge than you would on a 750. On a tight course or on the old slalom the 650 is a lot of fun. You have to lean first then turn the bars once its on an edge. Riding a Superjet you lead with the bars then it...
Air leaks are 10x more of a problem for motorcycles than for PWCs. Watercraft engines never operate in high vacuum except when out of the water. Motorcycles do anytime they’re not wide open. Skis with leaks will have idle runaway problems out of the water before it causes a piston to...
Piston rings aren’t an issue with a stock exhaust port. I’m sure the ski could use a good inspection and maintenance. Leave it alone if you are not prepared to make everything perfect. Disassembling and cleaning everything is a lot of work. You will make it worse otherwise.
Aftermarket hulls come in only two sizes, short and really short. Adjusting the hull area at the rear end and the pole length can make any hull perfect for different size riders and/or riding conditions.
