Hey everyone, I haven’t been on the site in a while, but I’m having an issue with my ‘90 superjet 650. I ride it for about 15-20 minutes and then it starts to lose power and if I get on the throttle it really starts to sputter and dies if I don’t pump the throttle. I read a few other threads...

Just wondering if you'd be interested in modifying another pair of footholds if I send you mine and pay you for it? It looks like you did a killer job on those!

Where did you purchase those footholds? and did they install easily? just a unbolt stock and bolt on aftermarket deal?

Thanks for the info guys! I tested the stator going off these specs I found. The charging coil didn't bring back any reading and the pulser coil read 19.1 which is out of specs 12.6-15.4. Just a thought but how fast can the magnets go bad on the flywheel and could that be the source of the...

does anyone have a wiring diagram or instructions on how to test if the stator is good or bad? I have a sparking issue where the motor cranks but no sparking, I've replaced the CDI, Ignition coil, starter relay, and overhauled the start/stop switch and no luck. I want to test the stator next...

I bought a 2.3 needle and seat to try as well.

Yeah that's why I bought every spring weight available to get my pop off pressure higher so it doesn't leak. Also, does anyone know what changes I would have to make for being at 4000 feet above sea level?

Don't worry about hijacking the thread. Haha. I just ordered a 2.3 n/s with 115 pilot and 125 main as well as all the different spring weights to try. Hopefully I can find a good combination quickly. I got some info from a guy saying the carb can leak if the motor rumbles really hard which my...

Thanks for the info!

The plugs are brand new. I bought the motor from a guy about a month and a half ago. Since it was out and there was some questionable wear lines I had the cylinders bored .5mm to clean them up and bought the matching pistons. I tore the motor completely apart and changed every gasket to new with...

Need some advise from someone who has had a rippen 750 supplied from a single carberateur. I have a SBN 44 right now but couldn't get it to run just right. I can't recall what my high and lows are. But I tried adjusting the high and low set screws in and out with little improvement. Don't know...

Will do.

Sounds good! Thanks for the advise!

Thanks for the info. I'm probably gonna try to get a CDI and try it again before I take it all out. Has anyone bought this Caltric brand electrical components off of amazon?

Need help figuring out what is wrong with my 1990 650 superjet. Plugs won't spark more than a couple times so engine won't start. I've replaced the starter relay, ignition coil, and added a ground wire. Still nothing. What else can I do? What else causes weak and intermittent sparking?

I am looking for a spacer for my 1990 piston port motor that will make my 44mm SBN carb further away from my motor. Anyone selling one or know where to find one? Thanks, Justin.
