I have some misc older dragbike parts I would like to sell. Make off on any or all parts. All will fit KZ900/1000 except for the valve cover.

The cams are factory hollow core z1-900 cams. ( 1 exhaust and 2 intakes. ) and all lobes look great.

The valve cover is for the GPZ1100 cylinder head or early MTC Rostock head.

MPS bottle bracket is for a 3.25” bottle.

The lockup cover has a little epoxy at the two bolt holes ( looks like the inside was machined for clearance for a larger lockup clutch.
All these parts have been sitting in the attic of my garage for about 20 years.

I also have a set of prostock cams, they measure .605 lift and 610 lift. $250.00 for the pair or $150.00 each

Why does my bike sound rich, but run great?
Metering rod carbs draw fuel differently and sound different from a jetted carb. Tune for the best performance, not the best sound. DO NOT tune your bike on a stand in neutral!! You will likely tune the bike
too lean if you're used to tuning a conventional carb that way.
