Hi Norm, Price sounds more than fair, there are a couple of photos floating around of what I want I'll try to gather them up for you. How about if I take say 3/8" copper tubing and bend it to shape and trace that onto heavy brown wrapping paper. I plan to bring the bike into the "skunk works" for the winter, for a complete tear down/redo, this includes remounting the engine so I'm 30/45 days away from giving the go ahead but this is my Christmas present to myself, so put me on the waiting list. You'll just be getting good at it by then! Happy Trails Walter F. PS pm me and we'll do it by e-mail

What ever will work so I don't make it so tight that it hits something like the cranks or kickstand etc it will be a one shot thing as shipping will eat a guy alive on a do over sounds like it might be fun?! if you use the pvc pipe(cheaper than copper) you can make it look just how it should be and also make some cuts so it can be make to fit a small box for shipping. just make sure to make alignment marks so I will know how to make it all fit right.

Those won't be a problem as when this pipe is on it's in "drag bike" mode, no crank, no kick stand-63 tooth sprocket on the rear. I'm gettin' a drag pipe for Christmas!!! too cool Happy Trails Everybody Walter F.

I didn't really get how a "Tuned Pipe" worked. Digging around the net I found an animation that thought I would share.

Quick question, If you ran exhaust into just a larger chamber after a stock muffler on a Honda 50 to cool and reduce noise, would it be sacrificing power?

Pretty good time for a pony on laughin' gas- I thought about using a dual pull lever for clutch and rear disc brake - pull the lever in clutch disengaged brake engaged, let go clutch engaged brakes disengaged, poor mans line-lock.

Well it better "LOOK" like a drag bike as that's all done to keep her low, sleek & quick. It's gonna be a trip!!! Happy Trails=Happy Times Walter F.

hey I wanted to say
I played with the length of the center part of the expansion chamber & it had a pretty heavy effect on the way the bike ran
taking one inch out required allot more fuel at idle & produced noticably more torque at low RPM while not pulling as well at higher RPM
I totally guessed at this pipe.... although I did make 4 or 5 all together
its a wonder it works at all
I ended up putting it back to about where it was erlier today
take care
