and maybe an FZR 1000 exup engine.
All thoughts and comments welcome.

Its a LOT of work to convert to IRS once the chassis is built, why not do it from the outset?
An FZR1000 engine is and OK'ish choice but there are better options for the same cash, CBR1000 for example. Have a hunt through some other recent threads to see what I mean.

The Exup engine block leans forward a lot as opposed to the CBR which is upright thus taking up less space. The CBR is also not as tall as the carbs are on the back and the Exup ones stick up, aka ZX9R, Fireblade, etc. Oh, and don't forget the Exup engine uses a vavle in the exhaust to houst the midrange.
