Oh come on you can make fit if you just twist it hard enough. It just might leak afterward. Who cares as long as it looks good!!! lmao, I was in rocky mountain atv the other day and they had a ton of billet gas caps for sale that were cheaper than what we paid. You may want to check them out. That was part of my frustration, I thought I would help out another hq'er. So I bought his instead.
