Review on Enhance Your Dirtbike's Speed with the Throttle Accelerator Dirtbike Lucky Seven! by Ryan Barton

Diameter too small for standard 7/8 inch rods. Had to use a dremel to open the hole. Gas pipe fits. Not sure why the grips have a hole in the end, maybe if you like mud I sealed your gas tube with silicone. The kill switch is back-to-front, so it kills the bike when it's in the "on" position. I removed the sticker and renamed it. I want to return it as I needed it for the weekend and didn't feel like waiting another week for a replacement. 15 minutes to get it working properly, if you don't have the tools or knowledge to fix it look elsewhere.
