Q: 2-stroke expansion chambers.

 

After a mild Google search looking for who/whom makes
 custom 2-stroke expansion chambers. I've pretty much
 come up empty.
 I bow to the collective knowledge resource of RMD to
 help me find a USA maker of said pipes.
 I am curious how much $,$$$.$$ it would cost to have
 a new pipe made for my newly purchaed SDR200 Yamaha.

I'll be surprised if you find one that you don't have
to design/build yourself.  Maybe if you look in
Europe or Japan where maybe they sold more of
them?

I *think* Jemco used to make pipe parts but can't
prove it now.  There was somebody that did and I thought
they were in Utah or about.  Found these guys
http://www.coneeng.com/conical_products.html
While that's not the company I am trying to remember,
looks like they could sell you the parts if you have
a design.

It's not all that hard if you can weld.  I tried it exactly
once and it sort of worked.  A "pipe" inside a stock
RD400 muffler to get around a stock appearing rule.


Go fast. Take chances.

Along with Kart guys, Micro Sprint guys also put 2S motors in sprint
car chassis and have to build pipes to suit. There's a local guy here
who's long been involved with building motors for the local micro
sprint crowd. Might be worth the cost of a phone call to see if he can
point you toward a solution. B&B Enterprises (302) 836-2012.

Can you just take 3 or 4 old pipes, cut/weld/fabricate and come up
with something that works pretty well?
Assuming you know about what it should look like or have somethign to
go by?

 


You may want to call one of the companies that repairs pipes.  I don't
know of any specific names, but some of the more 2-stink-experienced
around probably do.  You can send them your old one and (with any luck
at all) get something back that either is, or at least looks, new.
