I am currently living in Indonesia where the weather is hot and humid. As a result, I wear shorts when I ride my bike and gas engine Grubee 48cc bike. I have a black tear drop gas tank and everytime I ride my gas engine bike and hit a bump, my knee gets banged/bruised or cut from the gas tank. The part in the gas tank that bruise or cuts my knee/legs is the welded or seam area. Any suggestions/comments how to modify/cut the seams. I do not want to use duct tape as it looks to "tacky".
