Re: my banshee is still whacked out

my old bike had an air leak and i got high temp gasket materal it is like a tacky stuff and i fist removed the carb then i cleaned the ENTIRE carb in side and out then soaked it in gas and let it sit in the sun until it was dry. i then droped the float bowl and put the gasket stuff around edges to act like an extra gasket. then i put the bowl back on. now i checked where the carb bolts on to the head and put the gasket stuff on that. and at the air boot thing i put alot of gasket stuff on that to make a good seal and no more air leak.

98 You need to pressure test to find a leak. You can make your own tester. Check out duncan-racing.com or macdizzy.com for more info....SM

Re: my banshee is still whacked out

I used to have a problem with one cylinder running lean. The air intake was not the problem. It was the lower end seals. The crankcase seal on H2O pump side leaked, causing air to suck in and lean it out. It ultimately led to a broken primary drive gear.

Get it checked out. Do a leak down test.

Re: my banshee is still whacked out

As a rule, if you are riding in the same spot, and elevation, with the same type of fuel, premix ratio, jetting doesnt change. Now, if the temperature and humidity fluctuate, that could affect it.

If the jetting was correct before, and all of a sudden running lean, you have an air leak.
