Yeah, not sure why.... but it definitely has that WTF factor. I feel SO dumb for having a hard time getting 4 cylinders to work

Each motor is basically 8 "s1 /KH250" cylinders bolted on to cut up standard casings, with a 8 cyl built up crank, in turn they are bolted to a housing, gear linked and driven thru a BMW road bike gearbox, as the bike is pretty long already it would be difficult to put a transverse drive thru a gearbox. It has taken almost three years of hard work and he has overcome some huge problems to get here - - where do you even start to think about building a bike like this?

Oh, by the way, Simon is not an engineer of any kind - he oversees the building of shopping precincts etc.
