Webra do a 150 don't they? Would not be surprised to see a West eventually therefore. Would probably be purfect for the C140.
theres a 90 on the way and then depending on demand a West 160!!!! front induction rear exhaust with a mini pipe front outlet.
so if you want a West 160 in your Capiche 140 then demand it.
Pipes for the 140 for other engines shouldn't be a problem either.
ummm West 90 in the 50 Capiche, and a 160 in the 140... [X(]
