Fit generic black 2 Liter gas tank for motorized bicycle perfectly, and much better quality than original cap.All I needed was a new gasket for my old cap but (1) couldn't find one, (2) this cap was highly recommended on a motorized bike forum, and (3) a stinking rubber gasket alone is the same price as a whole new cap.
Fit my daughter's 49cc 4 wheeler perfectly. Great purchase.
Works fine on my Honda Elite 80
Did what i needed it to do! Title says it all.
My vented gas cap stopped venting (rust and/or sludge buildup) and this inexpensive gas cap was exactly the fix that I needed. One potential problem is that the rubber sealing gasket is much thinner than the one on my old gas cap, but in 100+ miles of stop-start urban riding, no gas has spilled out, even when the tank was completely full. It still doesn't feel like it's fitting as tightly as the previous gas cap, though.
