    Yamasaki 701SX

    SexPanther: Did you end up running the stock 61X breadbox pipe? I used a stock kawi 650sx pipe and it fits well but not supported that well. Ran the ski this weekend. Have a wicked vibration just off throttle! I think it might be the pipe hitting the side if the hull. I have to get it in the...

    I spoke with Robin. I didn’t specify when i ordered the kit i was also doing a 750 pump conversion. If i had he would had sent me a milled down engine coupler to allow the motor to slide further back. SUPER nice guy! He put the correct one in the mail within a hour I had a tracking number free...

    Did you have any problem with your motor mounts in your conversion kit? I bought the RHAAS 701 conversion kit and the motor mounts are off center to center on the 701 bed plate bolts by a 1/4 to 3/8 center to center… The exhaust side was 10 1/2 bolt to bolt and carb side is 10 1/4 bolt to bolt…...

    300/440/550 Correct way to put driveshaft coupler on conversion ski

    Got my 440 coupler off easily and threaded it on the x2 driveshaft required for the 750 pump conversion. Do i just put this on as hand tight as i can? Blue lock tite? I could put a pipe wrench on the shaft and tighten the coupler but dont want to marr up a brand shiny new X2 driveshaft. What do...

    300/440/550 Super trap discs on 550/701 conversion

    It’s the same size as the factory pipe stinger so i figure ill just run it. Are a lot of conversions making the rear exhaust larger in diameter? Sent from my iPad using Tapatalk

    Goki reed adapter

    Just get a reed motor! Better yet do a 650/750/701 conversion. I wouldn’t wast money on a PP engine. Just my $.02 Sent from my iPad using Tapatalk

    You can always run a poor mans b pipe(stock kawi 650 pipe dried out and lengthened 3 inches),Coffman sizzler, or pjs 3 piece kawi 650 pipe. Or a FPP 650 b pipe if you can find one. Downfall is you will need a FPP exhaust manifold to run these pipes! What will you run for a water box? I’m doing...

    If that’s a 1990 i think its a 440 with the decals replaced. I think 1991 was the first year of the purple lightning 550 with rear exhaust and reed motor. Only reason i say this is because a old girlfriend used to race and i have her last ski and it was a 1990 SX. Looks identical to the 1991...
