    Yamaha WaveJammer WJ500 Info?

    Whatever you do don't throw it out. They are turds but the kind you brag about to your friends not the kind that makes you wonder if there's something wrong with you. Put it up for sale as is. If you don't like the offers part it out. But don't send it to the grave

    Yamaha Super Jet Prop

    Search Google by using this formula ("Search subject" site:x-h2o.com) I don't intend to come off as rude, there are just hundreds of threads about this topic and what you want out of the ski besides a strong hole shot does matter. 75% of the time the answer is 9/15 impros hooker. That's the...

    White wash behind tray...

    Find someone local who has experience on superjets to ride it and tell them your concerns. You might have a problem but its hard to tell. There's quite a difference between a pre 08 superjet to an 08+, let alone a 440 to a 08+ superjet. Keep in mind the 08+ hull was designed as a balls to...

    How To Become More Involved

    Never take for granted having time and money. I've never figured out how to have both at once. I started out digging pennies from the couch for gas and saving up for parts to fix a break down. 10 years later I can afford goodies but get a day a week to ride and my ski has more power than my weak...

    Jetski hulls good bad the ugly

    Good: superjets have doubled in value. A/M parts get their money back. My b pipe is worth what I payed for my ski originally. Bad: superjets have doubled in value. A/M parts get their money back. My b pipe is worth what I payed for my ski originally. Ugly: there is no longer an oem

    Brave The Wave, Aug 7th,

    If I can get that weekend off this is close enough for me to drive in that morning, watch the show, and camp somewhere that night. If I don't plan on competing do I just show up to watch? What about if I'd like to ride my own skis in the lake that day, is that permitted?

    Custom/Hybrid Kawasaki js300/750 swap to a 300sx hulll

    If you want to have fun everywhere you forget all this, sell your stuff, buy an old waterlogged pig of a superjet. Same for old school freestyle. Every single 300sx freestyle build posted has been sold off to either start over (with a superjet as the base) or for money towards an aftermarket...

    Custom/Hybrid Kawasaki js300/750 swap to a 300sx hulll

    We mod to get the specific experience we desire. If that's turning really fast so be it. Welp OP decide what your game is. You said freestyle..so do you want to spend 100 hrs modding a 300sx or ride a freestyle hull? That's it really, in my opinion. If you'd prefer riding and learning...

    Custom/Hybrid Kawasaki js300/750 swap to a 300sx hulll

    You might be opening up a huge can of worms. From what I can remember the hulls are completely different. Engine mounts are different. Sx hull won't except 550 pump without modification. Exhaust exits out the rear. (From what I remember) The 300sx hull is better than the js300 hull but...

    Superjet cranks but doesn’t fire

    Your cdi is toasted. Or a sponge? Put fuel mix in plug holes. If it fires the cdi made a happy poopy. When it goes back to not firing at all hit up the jetmaniac and get a cdi. Even if it's not cdi it will be at some point

    Superjet - Bogging down after 3-5 mins at full throttle

    Stock you can ride it wide open all day. With b-pipe and an enhancer you should be careful. A lot of it depends on where you set the rev limit and your prop. I would start with the exhaust leak and deal with that first. If you were a sprinter running a 100 meter do you think you'd run better...

    9/15 10/16 Hooker or 13/16 3mm Cutback?

    Jetworks is a company that can be hard as far as communication goes, but their "A" prop and bored nozzle mod for superjets is undeniable.

    Super Jet SN 650 random dying issue

    Does it bog down and die then won't start or is it like someone yanked your lanyard off type of shut off? Will it fire then can't get out of its own way or no fire and an endless cranking? If its a bog I'd start carb and tear it apart, note the shape of the diaphragm and needle and seat. Needle...

    SN vs SQ pole length

    I never measured but the sn turn plate on rn pole felt longer than a stock sn system I went to rrp steering and it's about 2 inches shorter probably the length of all stock square steering. Why not install whatever you want and then cut the pole to match the +08 length

    SN vs SQ pole length

    They are both really long. What decision do you need to make? Rn cables work fine on squares, I believe they are physically shorter but have more throw. They also work fine for Frankenstein squares like mine that have been converted to RN poles
