    Superjet engine\twin carb swop

    Thanks for all the advice guys , I think I will stay away from the wrecked superjet , save up my pennies and lash out on a new ada head and if I can run to it , a b pipe. Will I have a problem with the revs bouncing off the limiter with either of these mods , and how would I go about sorting...

    Superjet engine\twin carb swop

    Thanks for the advice. I have the ski now for a couple of years and I love it. I looked up "FX1 ski" on facebook and came across this dude in a river , pulling backflips and barrel rolls on his fx1 like it was a piece of cake. Where do I begin to try that out , it looks nuts.. Check it out...

    Superjet engine\twin carb swop

    At the moment the engine is stock apart from a 46mm carb , boyesen duel stage power reeds and a protect exhaust. Other mods include Blowsion 144mm jet pump , 13/18 skat trak impeller , pump tilt kit , Tubbie Destroyer sponsons , a pair of rule bilge pumps and a few other minor mods. I hope to...

    Superjet engine\twin carb swop

    If I go ahead , I will more than lightly try to buy the complete ski , that should sort out any of the extra parts needed to make it work. Would a protect exhaust for a fx1 work with the superjet engine.?

    Superjet engine\twin carb swop

    A friend has a superjet with a badly damaged hull for sale. Wondering if any of you guys have fitted a superjet engine with matching twin carbs to your fx1. Is it a simple job to swop them out , or is there more to it than that , will it make much of a difference in performance over the standard...

    Sooty black smoke from exhaust...

    Hey fx1 buddys , I installed a set of Boyesen duel stage power reeds to my fx1. (Standard engine apart from a pro tec exhaust.) Started it up on the trailer with the hose running , it ran fine but black oily/sooty smoke started to shoot out as I revved her up.... Is this anything to worry about...

    46mm carb on stock intake manifold... ??

    Hey all you guys running 46mm mikuni carbs... Have you all paired them with the wetjet craze intake manifold , or have any of you drilled out the carb bolt holes and ran with the bigger carb on the original manifold , and if so how does it work. I have located a 46mm carb but am having...

    Which carb is best.?

    I had a go at removing it , got the carb off & unbolted the top of the intake manifold. I could see the top of the reeds tru the top of the intake , but didn`t know how to remove bottom section of manifold , couldn`t find any more nuts/bolts to remove , so I gave up... Whats the secret.?

    Which carb is best.?

    I had a new jet jet kraze when they were in production back in the day for a couple of years , and it never missed a beat. I think it had the same engine as the fx1 , just with the bigger carb. Did you have to remove the engine to fit carb and intake , or can it be done with it still in the ski.?

    Which carb is best.?

    Wondering if most of you fx1 riders are sticking with the factory standard mikuni 44mm carb , or have you ditched it for something superior, maybe twin carbs , or is the original still the best. ? Any advice would be greatly appreciated.

    Fx1 power fade.. ?

    Ok , but that throws up a few questions. Are they suggesting that the carb is rotated 90 deg. clockwise or anticlockwise. Is there a mounting kit available for same , as throttle & choke cables will have to be re located , air intake will be lower & on the side of the carb. (water intake...

    Fx1 power fade.. ?

    Hey guys , my ski has developed intermittent power fade when wave jumping or pushing it hard in to the turns etc. It has the standard carb & engine setup. I fitted new plugs , stripped & cleaned the carb + fitted a carb rebuild kit , but this did not make any notable improvement. It only...
