Are you at all concerned about the belt changing tension with the movement of the motor?
As I understand it, that's the reason motorcycle manufacturers always attach the swingarm pivot point to the motor in rubber mount motor designs. By going hard tail, you're defeating that.
i am concerned and have read up on a few rubber mount hardtails that have mentioned this. It looks like a lot of people run a pulley wheel with a chain which they claim solves the slack issue. I’ve also read about hardtails on these bikes with no tensioner, stock rubber mounts and a chain conversion with no issues. So I guess we’ll see what my experience is once we get to that point. I should note, I didn’t experience any issues running with struts which effectively does the same thing: locks out the swing arm.
thanks for pointing that out, I know that is an area on why a lot of folks chop pre-04 frames rather than these.
Quick update: Just got off the phone with LedSled and my hardtail is being made today so I should have it early next week. I'll begin teardown this evening and take pictures along the way. Getting pretty excited!
