I'm making an expansion chamber and I need some advice...

How long should I make the header?

Re: I'm making an expansion chamber and I need some advice...

Just cut stock header and weld it on, should match up pretty good, and clear pedals to.

No need for a header if your doing a jet engine swap

It should work fine if you make the header pipe 27 ft long

I'm going to try to keep the engine mild, maybe 65cc, I don't want to get crazy. I think you might be right, Ken. Maybe I should build another moped to trail behind me and carry the cones?

Re: I'm making an expansion chamber and I need some advice...

jason you should just weld two mopeds together length wise. you can have two headers one for each bike.

Re: I'm making an expansion chamber and I need some advice...

Use the pipe as your frame, mount engine inside the chamber, header problem solved. You will need a trailer for the stinger though.

Re: I'm making an expansion chamber and I need some advice...

I think we need to see how far can one go and get away with convincing cops its a "moped" maybe a multi cylinder snowmobile engine cvt and functioning pedals.
