    First superjet.. Rebuilt and ready to party

    Ive used Tom21 sponsons and love them. Have also used blowson destroyers and the worked well the Tom21 ones IMO were a lot better. No chine walk, more bouncy, and a bit more playful. There on my 1990 square but I believe we both have the same bottom hulls. Just my $.02 Sent from my iPad using...

    How fast does your JS go?!

    Pushing close to 80 hp in my Yamasaki. Don’t have any radar numbers but it walks away from my stock super jet and my jet maniac/ blue 718 square nose with all the goodies. Maybe back in the day when PJS was around or the other big company’s with there fuel injected basket cases they would be...

    Yamasaki 701SX

    Some guys machine down the bottom of the bed plate to allow the longer(I think) stock SJ mounts. From extensive reading over the winter the poly mounts Rhaas makes are very stiff and exaggerate the vibrations. The sock Yamaha ones are softer and soak up a lot of the vibrations these conversions...

    Yamasaki 701SX

    Only problem i have with them there in Australia and it takes a little longer for your parts.. I ordered a TDR water box from vintage jet ski in June and still haven’t gotten it! Also ordered a Custom Matt kit a month ago from jet trim. Hoped to have it on before the riding season ends. That’s...

    Yamasaki 701SX

    Looks good! Ill do that for sure but i have to wrap my super trapp water box with turf and zip tie it on because i have to be able to service the discs every season. I highly recommend the wax racing internal fuel fill. Very well made and looks good as well for a fair price. Don’t pay...

    Yamasaki 701SX

    I had a bad vibration on my Yamasaki.. first thing i did was cut the battery box out on the carb side front corner where one of the bed plate bolts hits it. Helped, but still there. I dented my 650sx pipe with a mallet to clear where it was touching the motor….still there. It’s a lot better but...

    Yamasaki 701SX

    Every time i called he picked up. Maybe he has COVID! That’s the general excuse everyone uses these days! Ohh, because of COVID…….BLA BLA BLA.. I had a good experience with him and he jumped right on it and sent me the correct coupler that day express shipping. I’d say get some regular couplers...
