Was hoping some of you experienced builders would have suggestion for a solution on my fuel tank mounting issue. I have a Micargi Rover GX, and standard Grubee 49cc engine kit. The fuel tank mounting studs are too short for the accompanying mounting brackets, or the brackets are not deep enough to fit the studs, either way. This fuel tank mount setup was obviously designed for a bike with a much small OD top tube. Is there a mounting kit that I can buy that will fix this? Or do I need to custom fabricate something to make this work?
