I’m looking for a top end kit for a Yamaha. I would like to see how well the engine runs before spending $6-$7 hundred on oem. Niche has complete kits from $1-$2 hundred. Anyone have experience with Niche or similar Chinese companies?

Hey all,
I need some input on a problem I'm having with my Kodiak 400 that keeps fouling plugs. First off, I've done a lot of work to this thing, most of it all in good fun. Brake work, cv joints, u joints, carb kit, checked valve lash, compression good, changed all fluids, etc... My problem is it keeps fouling plugs very quickly. I can put a new (manual recommended plug) in and it starts right up, runs great, idles great, picks up good. Doesn't stutter at all. I ride it for 1/2 a mile, it cuts off and won't start back up. I let it sit overnight thinking maybe it got to hot. Try to start it the next day, nothing. Put a new plug in, fires right up, runs great for another 1/2 mile or so, dead. The plugs come out and look carbon fouled with dry black soot on them. I don't know if this is a fuel/air mixture problem or a ignition problem. A couple of things that I noticed is I never need to pull the choke out to start it. Also, when it starts it automatically idles high like an automatic choke would do, then it comes back down to a good idle. Also I noticed that the air/fuel mixture needle valve screw does nothing when I adjust it in or out. I can screw it all the way closed and the motor still runs and idles good. Any advice would be greatly appreciated. I'm almost leaning to a ignition breaking down the plugs??
Thanks!

Hey guys, I’m new to the forum. What I got is a 2001 Yamaha Bear Tracker 250, got it as a project on trade and the problem I’m dealing with is a “no spark” problem and been trying to hunt down the cause for two weeks. I’ve replaced the stator, pick up coil, CDI, wiring harness, ignition, coil pack, spark plug, solenoid, battery, etc. and I’m still not getting any luck. Even tried bypassing the kill switch. I also noticed two things on this quad, another CDI under the back plastic by the voltage regulator, and a blue and green wire coming from the motor behind the foot shift, tried to hook it up but it broke off and I’m thinking the broken wire would cause it to have no spark, if not then I need someone’s help on this and wanna see if I can get spark again. If anyone knows why I have this problem, the help would be greatly appreciated.
