You won't! And that's where all these dreamers who've come up with these ideas fall flat on their faces every time! There's no easy route to a V4 (or even a 500cc V-twin).

The lastest hair-brained scheme on Facebook is to use RGV250 components to do it! LMFAO The things won't even hold together as a 60hp V2 from the factory, let alone as a 500cc V4 with custom crankcases. They're considering the most badly designed and unreliable "modern" 2-stroke barrels... and talking of over 160hp... dream on lads!

Any V4 project would need custom crankcases and custom cranks. You may be able to get away with using off-the-shelf barrels from something... something, anything other than RGV/RS! Basically, as already alluded to, it's totally unviable, unless you're insanely rich or insanely talented with all the time in the world on your hands.
