So I swapped out the Chinese Mikuni for a 24mm Nibbi. Put a 52 pilot and 125 main in there, it runs great but the plug was two toned. I jumped up to a 135 main and still two toned. Any suggestions? also the piston isn’t dirty at all, I just had the light on my borescope all the way down lol.

Badass bikes. Probably tons of funs out in the woods. You know where I can find those top throttle plates?

Those carbs seem much more reliable. do they make similar power? I don’t know if I could go back to the stock linkage setup. It always felt so poor compared to the slide carb “linkage”

I think carb might just be junk. Moved the float back to how it came from the factory. Put the 130 jet in with a new plug. I got one decent pull then it just starts cutting again. y’all have a recommendation for a carb? Was thinking a 24mm Nibbi? Don’t want to kill my pockets.

So I took apart my carb, cleaned everything. Made sure it was aligned right with my intake runner. I also adjusted the float to be 1inch above the flange. also changed to all 1/4” rubber line throughout with a filter in between. This seemed to fix the issue when I had the 130 jet in, I would...

Whoops. Here you go. also attached my fuel delivery setup. It’s no clean and there are definitely some restrictions/losses along the way. The problem is the barb on the cheap fuel tank is too large to run the same diameter hose throughout. Have to think of a way to do that. Possibly hose clamp...

Lol. My bad. 🤣 Here are some photos. Spark plug has the threaded portion on it and I’m unsure if I need the adapter for it. Clicks on fine without it. Also added a photo of the old stock coil.

Gonna do that tomorrow here’s a photo of the grounding.

Just swapped to a 130 jet. Fuel delivery is just a tank feed. Plug looks better but the cutting is even worse now. So odd. also attached a picture of the bike

It’s not. I said Amazon Mikuni. Pilot jet is stock.

Went back out. Had the air fuel screw just under a full turn out from fully in. Plug looks better, however still getting the cutting under WOT

Some photos of the top of the piston. Seems normal. I’ll twist the air fuel nut in a little to see if that helps.

No oil. I just put a new plug and a new coil on to see if it was spark related, still the same issue. Coil gap is set at .30.

Tested under load. It rides fine until I go WOT. Then it cuts out. Almost feels like the engine shuts off. It’s intermittent. checked the spark plug and it looked decent. I dropped down to a 125 jet. Clip is in the 3rd position.
