1976 KZ900-A4 OEM CAM Lift Duration???

05 Jul 2008 08:12

Hey all,

Researching which CAM's I want to go with and I can't for the life of me (Googled) nor in the Kawasaki Shop Manual find the cam lift duration specifications on the OEM camshafts...

Gears are 30 tooth sprocket with 122 link chain...

Anyone know?

I only want to use as a comparison... .365, .384, .395 or .410's. What to do, what to do...

Thanks,

Old Man Rock

any of them would be an improvement.just remember the bigger you get the more other weaknesses are going to show up.

Still recovering,some days are better than others.
