4/9/2021 4:55pm Swapped carbs and it still does it. I don’t think it’s the stator since that side didn’t take too much heat I’m guessing there aren’t any burn marks on that side will post pics.

4/9/2021 4:43pm Update: throttle was getting stuck at carb shaved sleeved and fixed that. took apart the carb and cleaned. Bike starts and runs and I can cruise but when I try to hit powerband the bike tends to bog I would say. I thinks a seal went bad from the heat Im going to have the bottom end rebuilt

Your tank might still be fine/usable. Likely what happened is when the bike laid over gas came out the overflow tubes on the carb and caught fire from footpeg sparks. The tank should be good unless the subsequent fire melted it. Take the tank off the bike, clean it up good, fill it with gas and check for leaks. Make sure you replace the carb vent hoses and route them correctly (up and over from each side). The bike will not run correctly with missing hoses or hoses that are too short or routed incorrectly.

2/16/2021 3:38pm I will check them out but I have to change my gas tank anyway that was the reason this started unless the bike just caught fire from me falling

2/16/2021 3:37pm I didn’t really check the air boot I will check that eventually but I remember seeing before that the number plate is different where it screws in it or the front fender but I think it’s just a very slight difference in the plastics

2/16/2021 3:34pm Sooo i was riding on the street and I fell... I think my gas might have leaked when I fell and sparked on the pegs or engine? I don’t know but when I got up and turned around which wasn’t even a second later the bike was on fire. I ran with it across the street and put it out.

1/16/2021 8:04am A dime is 1.35mm so I’ll just take 2 of them. I noticed My lever has some slop in it maybe it’s the original but I’m probably going to swap the assembly soon. I’ll take the measurement in a few hours and keep you updated. I changed the oil just in case that played a roll in it
