can any one help? i have a 86 250r and it runs like crap. it will idle till you go and give gas , then it with mist out of carb and bog down, if you try and put into gear and let out on clutch it will die, also if you put are box on it will flood out, when you turn fuel of it will run like crap till it gets low on fuel and start running better, is it in carb or base seals?
its 40 over stock pipe and carb. carb has 230 main and 30 pilot

 

Check your float level sounds like its too high and flooding carb
