I too have thought about the Yelvington USA Mechanical Reverse Pulley (M.R.P.), but I've converted my front drive pulley to a 30t from the stock 32t. In doing that I modified my swingarm with .25" thick gussets around the rear and bottom of the swingarm axle slot.
In watching the install video on YouTube, the left side mounting block will most definitely interfere with the welded on gussets. So I guess I'm out of the running for a new MRP.
Also I would want to make very sure that my Super Shox 14" lower mounts do not interfere with the left side MRP axle mount. It just looks very close, but I have not paid a lot of attention to the Super Shox mounting.
Still think it's a good idea.
Do they have a warning beeper when the ACC switch is engaged for reverse? If one backs into a parking spot and then partakes of some bubbly, when getting ready to leave you may be in for a shock if you take off in reverse...
