Hi all, names Todd live in Michigan I take the wife out trail riding on the quads when I'm not riding single bike track with my buddies. We roll around the Baldwin area. If anyone rides there give me a shout

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!!

View File Keen Motorbikes Cougar 150 Owners manual of Chinese Quad from now defunct website keenmotorbikes.com Have seen this under different names: Keen Motorbike Cougar 150, Rhino 150, NF150, New Force 150, Countryman 150 Owners Manual has wiring diagram at the end of the manual. Also included Engine and Frame exploded diagrams, pdf documents include parts numbers as well but I haven't found them very useful in finding the correct parts. Uploading to help out anyone who might have this quad but hasn't been able to find any info on it since it's a china quad. Submitter Benji Submitted 07/05/2018 Category Other ATV

just bought a 2005 kazuma dingo 150cc and need help figuring out how to properly connect new wiring harness. and proper hook up of vacum lines? any help would be greatly appreciated

Done, done and done! I just rebuilt the carb yesterday with brand new parts.. the carb is clean! I noticed it's spitting gas mist from the carburetor as if the intake valve wasn't closing all the way! Valve clearances seem good and timing too!

Clean the carb and look closely at it for plugged holes in the sides of the jet tubes . Blow out the passages in the carb too. Your description of the problem is classic lean running from fuel starvation caused by a plugged jet or passage .

Good luck, let us know ho you make out. If you know the year or approximate, get yourself a carb rebuild kit like:

awesome! Thank you so much!!
