It looks like a Megacycle number without the dash after the first 3 numbers... Looked at the catalog but it can't be as numbers starting at 1 are Honda numbers, Kawasaki numbers start with a 4.

I don't have a Norris listing to look up or it could be something unique.

Crower Cams (the car guys) use to grind custom Kawasaki billets for motorcycle racers, they did a Pro Stock cam for Kawasaki under the SBM name (Super Bike Mike) Those have numbers on them like SBM10 etc. but it could be something obscure like that.

Mikaw Topic Author Offline Sustaining Member Posts: 4894 Thank you received: 1853	Just called Megacycle Cams and they can’t identify either. Thanks for the help so far. Hopefully someone can break the code. 1976 KZ 900 A4 kzrider.com/forum/11-projects/613548-1976-kz-900-a4 1976 KZ 900 B1 LTD 1978 KZ 1000 B2 LTD 1980 KZ 750 E1 Kowledge Speaks, But Wisdom Listens.

Mikaw Topic Author Offline Sustaining Member Posts: 4894 Thank you received: 1853	No, not without buying it. It was found as for sale, I reached out and this is the only reply I have received. I think it’s being sold by an elderly widow. 1976 KZ 900 A4 kzrider.com/forum/11-projects/613548-1976-kz-900-a4 1976 KZ 900 B1 LTD 1978 KZ 1000 B2 LTD 1980 KZ 750 E1 Kowledge Speaks, But Wisdom Listens.

Injected Offline User Posts: 860 Thank you received: 385	If its cheap enough why not just buy it? It looks to be a race grind and probably around .460" lift (just by scaling the pic) Used Z1 cams are still pulling good money, if its not what you need you could probably sell it on.
