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!!
Hey Quad Crazy people, Im posting for a friend. My buddy has a Yamaha Moto-4. I believe its a 200 or a 225, not sure. Im trying to find out about the carb. The moto will run for a few minutes then just die out. Is the moto-4 the same as the blaster. let me know. thanks
Hey guys, new to the site and looking for some help. I bought my boy an 86 Moto 4 and it starts and runs very good, but it will just quit. It starts right up, but it is a pain.
