Most bike parts come in need of repairs, this is no exception. Would not recommend for a gift, only for people who have experience with these kinda kits.

This power pipe has the largest chamber of the off the shelf motorized bike pipes. It measures 13 inches in circumference and is the correct pipe for top speed. The length of the stinger is important. If you add a silencer cut off the same as the silencer length.You will need a wider crank on the left side if you intend to pedal freely. Or extend the pedal shaft.If you weld, the pipe can be rerouted under the bike.if you are tired of the mz clones like me this is the ticket.

Its a true fat expansion chamber. Fits perfectly on a Scwhinn OCC CHOPPER. Without modifications. It did however break it's rear weld in two days. When it does the gasket with bust, you'll risk your piston at high speeds. I had to use permex right stuff red 90 minute gasket maker. Keep in secure and I had to use a hose clamp to secure it. Be sure you use high temp thread lock on your bolts.

Has nice welds, not the best in the world, but definitely will do the job. The problem I encountered is anyone wanting to use it will have to find a way to avoid leg burns and use wide cranks.
