Upgrading stock tank on my 500exc
I’m upgrading my stock tank on my 2016 500exc to the KTM power parts 3.1 gallon tank(Acerbis). My issue is that the aftermarket tank is thinner and the original 17mm bolt at the bottom of the tank doesn’t tighten up as you can see in the picture. I don’t see a thinner nut listed in the parts Fische. Do you use one from a different year? Also what about going to the 90* spigot for the straight down one.
Thanks for any help.
