Yamaha Superjet -08
Stock 760 (non ported)
Blowsion head
Factory Pipe Type 9
V-Force 3 reeds
Green 44mm carbs (aprox 9 years old, but restored and gone thru this year)
2.3 N/S, 65g spring, 17psi pop-off. (Have to get back to you with the jetting specs)
Msd Enhancer
Rides in fresh water, around 150-200 meters above sealevel.
Around 15-20 degrees celsius in the water and evertyhing between 16-22 in the air.
Everything´s new this year and has 25 hours of time on them.
I turn to my fellow riders and hope that you can help me understand what causes my ski to stall.
It dosen´t matter if it´s cold or hot, how much i turn on both high and low jet screws. Sometimes it stall sometimes it don´t.
If I ride for 5 minutes at ½ throttle and hit the throttle it stalls, and when i head back for shore the cylinder is really hot.
If I´m going to make a "race" start from shore, it stalls everytime.
But as I said, sometimes it dosen´t stall when I ride and sometimes it does.
And I can´t see any pattern.
I should add that is has not been like this the whole 25hours, it started messing alot the last 1 hour. And now it dosen´t even make a difference if i turn my high and low jet out.
My guess is that it must be electrical or carb related.
What do you think?
I´ve probably forgotten something, so feel free to ask!
