I am working on a basket case for a friend. It is a 98 Big Bear (YFM350FWB). It came with a parts machine which is a 96, which I am coming to find out is VERY different from his machine.
Anyway, first thing is first. I checked compression, 150psi. Valves are set correctly, and the engine is in time. I cleaned the carb, and there was some junk in the passages. It is a chinese carb, which I figured from the lack of markings or lettering altogether.
The bike runs. It idles ok, but breaks up badly under acceleration. Pulling a new spark plug shows it is running lean. White strap, with no black whatsoever. So I have the carb adjusted with the mixture screw out way too much (about 5 turns), and the diaphragm needle lifted to the top slot. It is still not getting enough fuel (or too much air). It backfires through the carb, and cannot get above idle without carrying on. The carb boot is in good shape, so it isn't pulling any air there. I did test this as well by spraying ether around the boot when running, looking for intake leaks.
Anything big I am missing here? I am starting to believe that this chinese carb is the issue. This quad came with the original carb, which I would like to rebuild and use, but the mixture screw is totally stuck, and stripped way down in its recess.
Thanks for any assistance.

I'm assuming, it's alright to test the engine after adjusting valves without the rear axle installed? Can someone please verify this? I'm waiting on axle parts and wanting to get that done while waiting. Thanks! 🙂

Working on a 2016 Sportsman 570 and it has a new battery and spark plug. No codes, fuses all look good. It cranks for a while and when it starts it will only run for a few seconds before stalling. At one point it was running at 3000 rpm with no throttle input, then it dies. Not sure where to look besides messing with the throttle cable, so suggestions are appreciated, Thanks.

I bought a 220 for my daughter and after riding for while it cut off and wouldn't start back up. Found the cam and rockers completely destroyed. When I replaced the head and got it running I checked and had no oil pressure. Pulled the side cover and the oil pump was missing the plastic gear. There were no pieces in the anywhere to be found. The side cover didn't look like it had been off in a long time. I wonder how long this thing was run without an oil pump. Put a new pump on it and its been running great.
