So a few weeks ago ended up buying a 02 Bayou 300 for 100.00
Get there to see it and motor was gone through and parts missing, stuff not connected
and a big freekin bucket of parts and bolts. He said had no power and mechanic said it was
the wrist pin. Ended up leaving it in pieces and left like that. I end up getting most of it back together
and manage to get it to fire up. I drive it and has no power! No missing just no power. I figure check
the timing chain as he did replace that. Well I spin the motor over and guess what!
A blind guy could have done a better jobs. Just one question, I loosen the top bolt on the tensioner then remove it
right? Nothing is gonna fall inside the motor is it? just making sure, need this out before I can move the cam gear
to the right location. Thanks in advance Az
Haven't got a service manual for this yet so I'm flying by the seat of my pants I made myself a shifter extension to go up by the gas tank took my foot shifter off to weld it and now when I put it back on I don't seem to be able to find neutral. Is there some asinine reason that you have to do something internally when you change or remove the foot shifter? It was a simple take off weld put back on and dog bite my pecker it's not working. I hope this is something simple I've done and that's something I need brain surgery for. Cheers fellas I know y'all will have the right answers
Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.
What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.
Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
Thanks in advance.

I have a 1987-89 (not sure on the year) Kawasaki bayou 300 that has electrical issues, I have replaced the entire harness with a proven good/used one, new CDI box, and two brand new coils, problem is that it tests no charge at the pickup coil, so I replaced and tested again with a so called good one that had been salvaged out of a blown up 220/250 (not sure which, the left side cover is smaller than my 300) in Missouri. It has a proven good OEM stator. I am trying to avoid buying a new start and pickup coil because it is so expensive so if anyone has a suggestion please let me know.
