Topic: Cb500 yoshimura cams identification

[kayaker43]

I have two Yosh "TT100" cams also referred to as "Daytona" cams. They made two types and this was the hotter of the two. My memory is fuzzy and I can't recall what the milder street cam was called?

Does anyone have info or specs on either of their cams? I may be willing to trade one of the TT100 cams for the milder one?

Can you put a caliper on the nose and tell use lift?

I don't have access to the cams for a while. I'm spending the winter in Florida,.... house and toys are in Michigan. I won't be back home until May!

Can't remember the specs, but they did require notched pistons and stiffer springs?

The end of the cam should have POPS hand-engraved on it. Thats the way his originaly came back in the day.

I'm not trying to identify my cams, I bought them new way back when. I just can't remember what they called the milder street performance cam??

Thanks for the info,.. Don't know where I got "TT 100" from, but thought I remembered the 500 cam also being called the "Daytona" grind in magazine articles as well?

Then again I remember myself as a handsome and talented rider 30 years ago, but my friends seem to think that wasn't true?? Hey,.. that's my story and I'm stickin with it
