I went a different route with the 30T pulley so I could retain the stock belt. Reason being, if by chance I ever broke a belt while on the road, the likelihood of a dealer having my belt would be substantially greater than if I were running an aftermarket belt.
I pulled the swing arm and slotted it 3/8" allowing the axle to move further back. Welded a gusset underneath the swing arm to strengthen it and welded a piece of key stock in place for the cam to rotate against. Been running it like this for over 40k miles with zero issues. YMMV.

But theres no way I'd trust my welding abilities on a crucial item like that. If someone were to ask me to do something like you did, in order to retain the stock belt, I would take the swingarm and detailed dimension to a local machine shop or welder and have them do it. Too risky for an average Joe with a wire feed.

Belt drives ltd. sells a Gates Polychain 1" 139 tooth belt. I'm not sure why people keep saying these are hard to find. I would definitely stay away from the Goodyear Falcon belts, they have a poor reputation and track record.

Personally, I wouldnt consider grinding and welding on a critical item like a swing arm for bikes as heavy as these touring sleds. Very easy to not only weaken the part but also change the brittleness in the area of the swing arm most prone to cracking.

I agree - I went to a shorter belt on my old Glide. Fortunately for me a stock Sporty belt is just the thing.
