Warrior problems

Recommended Posts

I have a warrior that i bored .50 over. and changed the cam chain. Well the problem is:

1. It cranks really hard with choke on,and will only start while cranking with choke on and quickly shut choke off while still cranking...then it fires.

2. When i rev it up a little it takes a while to come back to a idle. And dont idle well.

3. When it is idling, It makes some kind of flat sound and dies, Not a sputtering die, but a brupt sudden die. Almost like somthing in the engine catches and kills the engine. But not always....sometimes it will make that nosie and sounds like its gonna die but goes thru it.

One time when i was cranking it the starter wires started smoking. I also changed the cam chain.My guess is a timing issue. I unscrewed the sight window on the fly wheel and put the "T" on the mark, and put the cam sprocket mark on the top notch on the head.

The catching sound that sometimes kills it concerns me. Could it be the idle gear off the starter? Or could it be my starter messing up? I thought maybe a gear in tranny catching slightly, but i took chain off and watched the sprocket, that wasnt it.

Hhhhmmmmmm Did You Just Do These Mods Or Did It Run And Just Start This? What Compression Does The Piston You Put In It Have 50 Over Is Pretty Big So I'm Sure You Have Alot Of Commpresion In There. If This Just Started You Might Need A Larger Cam To Get Rid Of The Exhaust Gases It Might Be Vapor Locking In The Haed. Till It Bleeds Off. I Don't Know For Sure Though Thats Sounds Kindda Odd I Would For Sure Check The Timing One More Time I Had A Warrior And Had Nothing But Problems With The Cam. If Its Off That Could Do It.

ok...I think i might have a timing problem. I also have a stage 1 hot cam. So do i still set the timing the same? its .50 over and hot cam. I just rebuilt te carb and started it, and its still doing the same thing.

Does this sound right? I moved the cam gear one link towards the back of the bike. And it starts easier and runs a whole lot better. Could that be because of the hot cam why I cant have it set to the factory timing marks?

      First time using this forum.  Owned a Kawasaki dirt bike once, had no issues.  But I picked up this 4 wheeler at an auction.  They stated it ran, but only needed a battery.  Well I do not believe that was all true.

      Some pictures are attached.  Not sure why, but the whole air filter stuff was removed.  They had some small thing inserted as a make shift air filter.

      I purchased a battery to try this all out.  Waiting to return it and get the proper size, as it was too big for the battery box.  But here is my issue I had while the battery was connected.

      1 - The lights on the steering column did not come on.  Not sure if they work or not.

      2 - The starter solenoid seems to be bad.  I have a new one on order. 

      3 - In the pick, there is another rusted part.  Not sure what that part is or what it is used for.

      4 - What is the 12v rectifier?  square bodied part.

      So when I hooked the battery up.  Pushing the start button did nothing.  Pulling the cord to try and pull start, it turned, but would never fire.  I have put in a new spark plug as well, it looked worn out.  With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.

      I have read a few other threads and it stated something about needed the neutral light on.  SOmething about a kill switch.

      Any help would be appreciated.

      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!!

      hey I'm dave westfall I'm new I just became an official member of this site a few minutes ago. Ive been crazy about quads and bikes since I was about 3 and ive always done my home work on them figuratively speaking. I would say for comparison to the common man that I am pretty knowledgeable about them. its been my passion about most of my life. I love talking about quads and bikes so if anyone out there would like to talk with me about mechanical subjects or about person experiences while riding or just shoot the breeze please feel free to chat with me. I'm looking forward to it.

      I recently bought a 2000 warrior that needed motor work. I got it all put back together and can't figure out why I have no electric coming on, it has a new battery with 12.5v the fuse is good and I believe I have all the ground wires connected. Any help or suggestions?
