Just had a E3 250 put on 2 weeks ago. After riding the bike hard last nite came home with 2 grooves cut from the bolts in the fenderwell. I do have Arnott air suspension and had it lowered about 2 1/2". I am going to have the studs shaved off. Anybody have a similar problem? Diameter of the 250 must be larger as I didnot have this problem with the 240.
