I know a lot of biturbos end up getting hacked and welded to work on other bikes.
I am looking for someones left over header. I guess the header from any tomos performance pipe would work, but I reckon someone out there is more likely to have a tomos biturbo header than any other,
It does have to be a tomos header though. Or a derbi or something. Something that kicks to the right and is nice and fat.
Trade or cash.
