Yeah the stuff from home depot is nice!! That's what I have

Well the lighting coil fixed the problem!!

I had these on there lawn mower filters from autozone, I pulled them and replaced them with automotive filters and no more WOT bog! the filters must have been too restrictive!

Yeah it was the best trip we've gone on yet!!!

Thanks I will try that out

I have a 789 with dual 44's, individual fuel lines to each carb with some small lawn mower fuel filters from autozone. Im having a problem, when I snap to full throttle it will bog until I let off and slowly accelerate then it will go to almost WOT but not quite? Ive been reading on here about...

Mine does the same thing? Ive checked the filters also. What else could do this?

WOW !! nice build!

Adding turf and footholds is one of the best things you can do to a 440, besides adding a bigger engine. I used the 550 ebox also, theres a wiring diagram on here if you search. Heres a couple picks

Poop! thats the expensive one!! The stator I got the second time looks like it been sand blasted? maybe its messed up?

Yeah with my batt fully charged, the voltage doesnt change when I start it. Stays at 12.3volts. Im gonna order a new yamaha lighting coil I guess, sucks Ive been fighting this prob all season :( I think the pulser coil is week also due to the fact that when my batt gets under 12v it sounds like...

I just measured the regulator I just took out and it not showing anything between the red and black wires? Im gonna take it out tomorrow, and after that Im pulling the ebox again and recheck the green wires.

I see, I measured the green wire wrong then, but yes I measured the red wire from the regulator to ground. Thanks for all the help too

Ok I put my ebox back together already so I didnt check the green to ground, but I switched back to my other voltage regulator and cleaned all the grounds. I checked the voltage at one of the green wires from the stator and it was putting out 2.3 volts? (AC with the engine running) and...

The resistance is 1.0 on the lowest setting on my meter , can I test the ac output of the stator at the green wires?

No problem man , I would be sad if mine was stolen. I will keep me eyes peeled on the eastside.

I saw this ski on Craigslist in the Detroit section recently ? Might wanna search Superjet

Oh I must have worded it wrong my batt only dies when I'm riding, its fine in the ski siting. I will test that tomorrow for sure thanks

I swapped out the regulator already once, I'm thinkin the charge coil is bad? I would buy a new regulator if I hadn't just bought one that was supposed to be good. Thanks for the info I'm gonna get my meter out tomorrow and test that and the charge coil output.

Ive got a 90' superjet with a 62t engine I built over winter. I bought a stator and flywheel from a guy on here over winter, and a new gel battery. SO, when I charge the battery before I ride and ride for 2-3 hours then check the voltage on the battery its a little over 11 volts! Then if I dont...
