Ok...I keep reading posts concerning gas tank leaks on this bike. I am about a week or two away from putting one of these on layaway. Are you guys getting leaks because of taking the tanks off and putting them back on or do they come that way from China? Is it a defect in the design? I never plan on taking mine off so will I be alright? I would like to know BEFORE plopping my money down. Thanx in advance.
