hi all ive got a weird driveability issue w/ my ext 580 efi after 10-15 min of ride time loss of pwr, bogs like a stuck pig ,but will rip good until problem occurs charge coil 1 tests low when cool any suggestions?

Could be a couple of things Fuel pressure needs to be a steady 36 psi. Stator could be going.

Have you tested it warm?
If it's reading low cool, then it may be ready to fail.
Blain1 can get you a good price for a reman stator if needed.

Yep do the fuel test as well as test the stator when warm! Get back to us with what you find! Also test the compression @WOT!

thanks for the info will do the testing,still learning about these 2 stroke driveability diags & repairs, hopefully this will come to a good diag

so how much for a new stator RJ , i was the guy that found a broke thermostat .,, yea not it , ran good till i got 2 mins down trail and BAM , bogging again ,,
check stator readings and 44, 551 605 ,,, that cant be good

Blain1 has them for {I think} around $150.

that was just after it was running and bogging .
so what are the ohms 45 450 500 < when cold > correct ?
