If anyone has a js550/550sx stator lying around and would like to sell please let me know. I am in need of a new exciter coil and can’t find any of them online for sale.

Any half pipe that will fit a js550 with a jet power manifold, I will be interested in. Due to the current pandemic, below 125$ I would be very interested in

Not really a crazy interesting topic, but i just have to get this out there. I dont ride to freestyle or race (although i like to carve more and go fast rather than do tricks). Truly the reason i ride is to be on the water. I only run a 550, but thats all i need. They way i like to ride is to...

I hate this stupid turf that wont stop peeling. I have it on my rub rails, and whenever i sub or stab, after a while, IT ALL PEELS UP. I really want to know if anyone has tips on this, cuz it really makes my ski look like crap Sent from my SM-G930P using Tapatalk

My ski takes on water when it sits there in the water. It's totally fine when I ride, inside is bone dry. Just when it sits. It takes on water. This sucks cuz my family has an island we chill at in the summer. I take it across the lake and stay there overnight a lot. But when I wake up the skis...

Alright Guys! so i heard about the new Rhaas kit that just came out! but one tiny problem... thats out of my budget! so i came up with some ideas on increasing the size of my 550 pump for under 150 bucks give or take. so first off i want to buy a nice skat 15.5. Second I want to get a stubby...

Ill start. im 14 and ride a 550. I hit my dads wake and got huge air off of it. Especialy because of my age, and that i have only been riding for about a year now, I think this is pretty good ;)

I have a 88 js550. I have 200 bucks to buy parts. i found a deal on a top end kit with forged pistons for 60 bucks. leaves me with some xtra $$$. are these parts listed give me the extra power i want...

Sorry for making all of the new threads. just so many questions need answers. but i have a stock js550 with 110 psi comp. can i safley advance the timing all the way for more power, or will i just make the thing detonate. i heard it can make the thing like a rocket and some people say the thing...

alright guys! my question is what mods are cheap that i can do and expect a decent power increase. I heard that advancing the timing all the way will give it mre power thrughout the whole powerband. is this true? also i heard porting gets you somewhere. what else can i do with this that are...

Alright, I know this question is asked a lot, but this is my first conversion I want to do so here are the questions. 1. whats the differences between a small pin and big pin motor 2. Which one should I get 3. what do I have to do to the 750 crankshaft coupler to fit the 550 driveshaft...

This is my edit I made of me on my js550. I'm 14 years old and I'm getting better. Yes, I know before anyone says it. I already know my nose stabs sucks. I only have been riding about a year now, but I barley got to ride this series due to the thing breaking down all the time (typical 550...

Hey everybody! Summer sadly came to an end, but I'm still riding every weekend until Halloween time. But I have a problem with my 550. I can have a blast on it with my friends, but it sucks when it takes on water. I don't know why, but it doesn't take on water when riding, just when I Park it to...

Anybody got an answer. I'm running a stock 88 550. It currently has the jet power exhaust system Sent from my LG-LS970 using Tapatalk

Hey guys I want to say thanks for everyone who helped me on the forums. I got my ski in the water and it's running like a champ. But I got a question about boring one if these things. I just got a couple of questions about them. 1.) how much can you bore them out 2.) Is it a good mod to do...

I'm just wondering if anyone knows how to remove these things. I got a leak coming through one of the holes. Sent from my LG-LS970 using Tapatalk

Ok. So here the problem. This is what happened to my jet ski. I finally got the spark and timing just right. So I took it out for a test run. So I realized that after about 5 minutes it would REALLY lag in tourqe. After that, it wouldn't go over idle. Then it just stopped. But im just wondering...

OK, this is really stumping me. So wayy back at the 4 of July weekend, my ski was running fine. But it cut out on spark. A few hours later, it would regain spark. But only for like an hour. So after this whole situation with my jet ski having bad timing, I knew that the coils were on wrong. I...
