Hi everyone, I received a 98 Yamaha Timberwolf from my brother for free, and I'm working on getting it going.
I am having the following problem:
The engine is backfiring through the carb.
I have done the following to try and get the four wheeler running:
Rebuilt the carb and set the air screw to 1-1/4 turn out and the circlip at middle position 3
Replaced the coil, because the cable was loose at the coil end
Repaired the main ground, coming from the battery
Replaced the ignition switch, because my brother couldn't find the key. New switch tested good
Tested the kill switch and it tested good
New coil tested goodfor both primary and secondary coils
Pickup coil resistance is at 195, which is correct
My source coil, is where I believe the issue is. The resistance is 310ohms, and it should be between 428-523ohms
When I opened the stator housing, there was significant oil, which I have read is normal. Does it sound like I'm on the right track replacing the source coil? Could this be causing my backfiring issue? It looks like the source coil is part of the stator assembly, is this correct? 4BD-85510-20-00 STATOR ASSY

Hey all!
I'm on a mission to buy my first UTV soundbar as a gift for my dad(a newbie on ATV). I'm aiming for something that offers great sound quality without breaking the bank – my budget is around $250. Right now, I'm considering options like ecoxgear, kemimoto, and boss.
Does anyone have experience with these brands or specific models that you'd recommend? Any advice or suggestions would be super appreciated!

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.

Recently picked up a 1991 Lt230e for repair. Compression is a little low Id say, around 80psi, I also have spark but the spark is odd . When cranking the spark is a constant arc. I’ve got it to sputter but never fully turn on. I believe the spark is my issue, being constant and not detonating at the right time. I’m not sure whether this issue is an electrical fault like some missing ground, a faulty cdi, or a timing issue. Any ideas where I should start?
