Monster GY6 engines

Though is has been a quiet summer, we still managed to keep ourselves busy with another project.
What you are looking at is 2 brand new monster GY6 engines.

You are probably wondering whats so special about them?.

Well unlike all the chinese GY6 clones, these GY6s have a special case which allows us to use a much larger 67mm bore, the normal GY6 can only manage 63mm.
On top of that we use a monster 8mm stroker crank to make a rather insane 231cc!

Theres a little more to these engines besides a large displacement, they also have a hand ported big valve head (still 2 valve by the way) custom intake manifold with genuine Keihin PWK carbs.

Both of these engines look the same but they are for different uses, one of them is for road use and the other is for the drag strip.

Power output..... well its unknown as we are the only people to do this setup, but i would guess about 20bhp with a mega flat torque curve.

Enjoy the pics.
