Hi 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've got some good parts left over from my recent 4wd 2003 Big Bear adventure. Used on 2000-2010 Big Bears.
Very good complete head-fits 350 also, came off 400 2002, Have timing chain, gear, guides, case & trans (2wd)
Fuel tank, harness, misc. electronics, front shocks/springs, also have some other stuff.
Most parts also fit some 90's models, (Kodiak 400 '93-'98), check it to verify.
Located near Chattanooga, LMK what you need, offer, cash/trade.

I have a 2003 LTZ 400 that i bought a few days ago. The quad was running fine until last night. I let my brother ride it down the street and back and i didnt notice anything etong with bike. Then my neighbors friend came over and said "can i ride it?" I said "sure" so he ripped it down the road all fine and when he got back it died right in front of us. My brother said it was dieing on him also. He also said that he wasnt using the clutch to shift. I told him he was an idiot. Im throwing that in there incase that caused a problem as well. But today i go to check it to make sure its getting fuel which it is and replaced the spark plug incase it wasnt getting spark but it is. So i started it and it was having a problem starting then i got started and was reving at idle high. So i took it around the block and it died on me a little bit down, so i try to restart it and it started so i kicked it into 1st and it kinda launched on me and started going with the clutch all the way in. Then it died right after and wasnt running right during that process and was idleing all over the place and just died and now i cant get it started it again. Before it would start without the choke or priming it. It would start real quick now i cant figure if it needs to be rejetted or something else. Air filter looks clean also. But any help would be gratelly appreciated!
I turn the key on and the dash lights up, the head lights work... I push the button to start and nothing happens, no click/crank, no noise at all. It will pull start, I can jump start it from the battery to the starter, and I replaced the starter relay. IWhat could it be???
Oh , and it is in Park,and I tried the kill switch several times in both positions, that does make a faint click, and sounds like it’s working
