Okay, so there are a few things i want to do to my bike. 1) so, i have been looking for a silencer and it doesn't seem like there are any pre made ones. (if there are tell me where to order) So i am going to build my own silencer. Here is my idea: Im going to cut off the little pipe at the end of my exhaust, And thread a brass nipple into it: Then, i will take a soup can and drill a hole in one side and thread another brass nipple into That hole and open the other side half way. Then i will fill it up with some product that i need help deciding on and close the half open side. i will weld it shut and drill some big holes in it. Then i connect the two brass nipples with some heat resistant tube. Here are my questions: What do i stuff the can with WILL IT SILENCE THE EXHAUST? 2) I want to turn the air system into a forced air induction system WITH an upgraded air filter. Here are my questions: Where can i buy a air filter for these bikes SPECIFICALLY HOW DO I LEAD A PIPE AROUND THE BIKE SO IT FACES THE FRONT to make it . a Forced air induction system 3) how do i make a boost bottle, what size pipe do i get and how long of a tube. I have a 66cc engine.
