both the TDM and the XT660R headers will work but those are 2-2 headers that require quite a bit of reworking (tube bending, welding) to get to a 2-1 and the 2-2 both foul up on the side stand.
The home-made 2-1 I referred to was like this; similar but of larger Ø that the original and, above all, routed under the bike so it could not possibly ground. the centerstand must beromved along with its right bracket for this. The Cup has no center stand.
my racer in its first form.
my street bike until I rebuilt it for a friend as a track bike. It has the REMUS system
Like my own, this has 32mmID (OEM=28mmID) headers leading into a much larger collector. It is also longer than the OEM system. 100 of these were made; they do occasionally pop up on eBay in Holland and Germany. Remus has two standard cans that fit, a refractor(civilized) and an absorber(loud). I had both, one for MOT and one for real-life.
BTW, this bike has dual TM38 with open stacks, a one-off aluminum seatframe (black anodized), Marvic mag wheels and ...
XTZ headers will also work as will probably those for the Baggi but these are scrambler-type headers and it is a
VERY CLOSE fit.
I have a SRX/TT cylinder and head on my XTZ bottom end in my own Skorpion:
You can see the 35mm headers from Devil in France (well done, all slipon joints with springs) and the matching LeoVince can also for the TT. Believe it or not, this stuff fit out of the box just as you see it!
BTW, the
Gilles rearsets are officially available (from any dealer or from GIlles or from me) for the Skorpion (my doing): AS31-MZ01R; they are plug and play.
I needed only to make a decent bracket for the can.
I am reasonably sure that the XTZ/BAGGI stuff will also work like this
BUT they will not clear the radiator in the original position. Mine is aircooled.
BEWARE: the TT/XT/SRX stuff will not work with the watercooled engine because the placement and included angle of the ports are very different.
For those interested and while it is part of this thread, I am running a Mikuni TM40 with the Grizzly branched manifold:
I also neglected to mention the
BikeWorx TM42 manifold kit which is or rather was plug and play; AFAIK he is no longer offering it and we bought all 5 manifolds he still had on stock (no, they are not for sale). Not exactly cheap up front but probably most economical in the long run:
It came complete with carb, battery box, K&N filter and twistgrip cable. Obviously, the airbox had to be removed.
I used this setup both on the road and track.
here is a friend's Skorpion with that BikeWorx (one of the 5) manifold and a TM40 with K&N. I gutted the OEM airbox, leaving the side to hide the setup and the battery carrier intact. He als has one of my sets of TZR 125 wheels (3,0' and 3,5" Brembos) with a 130/70 rear tire(like me) and he has German MOT for all of it!
