KX250 Chassis With 500 Motor
gwcrim:
I have a crazy kind of bike friend who happens to be a welder by trade. I mentioned this idea to him and he offered his services. That takes care of a certain portion of the project. There's a machine shop nearby that has done some custom work for me in the past. There's another situation solved. I'd most certainly do a compression release during the tear down.
Just need to get answers on this pipe situation.
Then I need to get over the idea of sacrificing a bike. That will be the hardest of all!

So Hillclimber, what did you use to fabricate that pipe?

I cut along one of the factory seams, rotated the pipe to where I needed it,tacked it, then made one more cut,rotation and tack weld. Just route the pipe to where you need it to go. Try not to change the internal volume and/or dimensions of the pipe much. Here is an interesting link to Two Stroke Pipe theory:

Also download this PDF, very good info if you've ever wondered about two strokes in general:

As far as I remember Flow make the formers that stamp out the aftermarket expansion chambers, it said something about it in Eric gorrs book but I can't find the exact wording right now.
I assume that they have also done so for the Zipty spannie but I can't see anything about it on my zipty spannie :?
gwcrim:
Thank you Hillclimber. I suspected that's what you did. Looks pretty good, though a bit impractical for the every day rider.
I kinda thought that Flow was the name on that pipe, but since ya cant see the rest of the tag on it, I wasn't sure. Do they have a website?
