Here is the place to ask questions about working on your 650.

In the process of building a souped up ex650 engine. First step is tearing it all down. When I removed the flywheel, I noticed a slot for a woodruff key, but there is no corresponding slot in the crank, nor a key! The manual speaks of simply mounting the flywheel back on the crank (and reminds you 10 times to clean the taper shaft), but says nothing about orientation for timing. Can anyone help out/explain this to me?
I checked my spare flywheel and sure enough, a slot for a possible key. I would say Kawasaki used part of the flywheel for other engines or designed it for possible future use in other engines. There is no orientation for timing, like a lawnmower flywheel, because the timing rotor and pickup sensor/coil is on the opposite side of the crank under those two slotted caps in the engine cover. Your flywheel just slips on like a snowmobile drive clutch. By all means, clean your shaft as much as you need.
