In the beggining there was WJ 01

Check out the idler gear is grinding on the aluminum support below.



A cast aluminum impeller.

I could not get the valve cover off due to the impeller bolt is rusted on. Yep that is right, if you notice the valve cover is convex under the impeller to fill the void. You can't get the valve cover off without the impeller off. I can almost taste those cams.


I am planning on going all the way down to the crank. I want to know if this is a 400cc motor or a 432cc.

Cool! I hear you. Is possible it might even be a stroker crank according to timbo the factory was experimenting with stroke.

Cool stuff. Looks like it uses a different main bearing? Cool stuff.

Yeah I agree, the engine came with a spare rod and piston, but I won't know if is the same one that is in the engine. The rod is a bit thinner on the big end and longer with a bushing on the wrist pin side. The piston says 97 JE on it and the wrist pin hole is larger than what is in the rod. It would probably match the rod if the rod didn't have the bronze bushing installed.

The intake looks cool! Do you also have the other parts of the intake?

Are the pump gears just pressed on? I have a set of metal gears that are almost a press fit.

According to my brother that is the motor in the bikes when cannondale raced the US open supercross in vegas.

How many of these engines are still around?
