Does the YFZ have some sort of built in decompression system? I know their is no lever. I thought I heard they had some sort of decompression system built into them. If they don't they would be a ***** to kick start. I remember when the 426 came out racers were losing races because their was no decompression lever and they could not get the 426 kick started fast enough. I was wondering if the YFZ has some sort of decompression system. Anyone know?

There is a decompression pin in the EX cam.

The '03 YZ's featured auto-decompression, so I would assume that the YFZ has the same thing.

Yes, the decompressioner is part of the exhaust cam!! It works off of centrifical wieghts mounted to the timing gear.

The exhaust cam timing gear, and decompressioner.
