Anthony Marceau posted a topic in Yamaha ATV ForumHi everyone! I have a 1986 yamaha moto4 200 that's been sitting for a while! Cleaned the carb, replaced engine oil, put fresh gas in it. Got it running and went for a ride! It was running great just a little backfire once in a while! I barely made it home on the way back and now the bike won't run at all since then! It will start if I give a little bit of throttle but dies instantly as soon as I let go off the throttle! And even if I try to rev it up it'll sound like its not getting enough gas.. it revs up a couple hundred rpm's and backfires through the carb.. it almost sounds as if I was trying to take off from zero in 5th gear! Nothing is seized though! I dissasembled the head and the piston and cylinder are fine! Rebuilt the carb, replaced the ignition source coil.. I don't know what to do anymore.. compression test shows 90 psi Specs are 128 psi but i'm not sure if I trust my compression tester.. any ideas? Thanks!!
i have a 2005 Polaris magnum 330 4x4 when i would turn the key to start it nothing is getting power so i replaced the switch and still nothing ive checked all the wires they checked out ok but if i run a wire from the battery to the switch everything works dont see and fuses or any relays except the fusible links by that come off the starter solenoid and they test out ok
