Hey Joe this is ryan from facebook. Glad you're happy. Joe means the needle went past the mph scale into the odometer. Just another tip, you should overengineer the mounting bracket like a mofo. Vibrations, bumps and potholes kill pipes that hang. Once I swapped from the mj50 2 speed to the new lc50 2 speed engine I lost my right side swing arm mounts on the engine case so the arm I'd usually use to mount extra brackets to was lost. I used the the part that connects to the axle to bracket the pipe to in the rear. Works really well but any deviation in axle straightness will send vibrations into the pipe so I had to use a dial indicator, propane torch and a hammer to ever so slightly get it perfect. The longer axle is from the mj or the pw rears, the bearing and bracket dealio is from a pw.
