Looking at various options to buy / fabricate tight fitting 4/1 system for my F2 cafe racer project. Love a yoshi pipe but hens teeth scenario applies (US sourced copy possibly an option)
If I go down the fabrication route, wandering about header pipes as starting point. SOHC 750 options limited but DOHC 750 / 900 more abundant. Pretty sure the answer is no but are these anywhere near compatible / easily tweaked?
Any advice appreciated.
