I either need to reposition my handlebars via risers.........or get my arms lengthened. I thing the changing the bars or getting risers would be cheaper. I have access to a full machine shop including CNC, so I think that I will make my own. My concern is how far that I can actually deviate from the stock location without running into trouble with the controls. I was thinking of mocking up a riser to check for fit. My question is for those that have risers...what would be a good starting point as far as maximum rise and pullback?
