I don't have any advice with drag bars specifically, but I put some Biltwell bars and risers on my bike, the only issue I had was I had to drill out the top tree to accommodate the 1/2" bolts of the new risers. I would try to find some that fit the stock holes, but if you don't mind drilling out the top tree then it doesn't matter really. Also, be mindful that whatever you buy will fit with all the stock cables and brake line, etc.
Never argue with a fool: onlookers may not be able to tell the difference.
