Open-Primary

Energy One
I currently have a 2008 Big Dog Mastiff and I'm looking to put on an open primary belt drive, because I'm sick of chasing a Primary leak and I want to add a piece to make the bike even more unique. I see most companies don't make them for BD specifically. Does anyone have any suggestions that they have used or have a reference? Thanks!!

Have you tried flat filing both the innner and outer mating surfaces? The Pitbull wouldnt quit leaking no matter what I did until I flat filed the outer cover. It had several lips around the edges. Cleaned it up, no more leaks. :2cents:
