Running a forward facing carb, and having problems with how high the carburator sits? Some carbs have a problem when angled too high in the front, and this can cause the engine to not run right, and have problems feeding fuel properly!
Before (Without Flange):
After (With Flange):
This flange also turns the carb in more to the center of the bike so that when running a fat tire setup, the carb doesn't hit the frame, and when running a normal wheel, having the carb centered gives the bike a much nicer look... It also more importantly angles the carb down a bit so that the fuel can sit more level in the bowl, and you can have a much better running motor!
