YOSHI ST-L1 CAM possible regrind

[Z1streetfighter71]

While on holidays and possibly a few beers in i threw a bid on a set of Yoshimura ST-L1 light weight cams that had upper lobe damage on the inlet cam for £110 to my total surprise i won. Now while i kinda know the answer im just looking for a second opinion on the severity of the damage from what looks like the cam rattled free from what could have been a cam cap bolt failure or incorrect torqued cam cap. The damage is across the cam but only minor scuffs to the other lobes but this is by far the worst. Im thinking regrind but second opinions are always welcome.

If the lobes are in spec and not worn through the hard facing you may get away with just dressing any dinks and high spots with an oil stone and just use it.

See i figured the same but was leaning on the safe side, all other lobes have little to no damage bar this one where a noticeable chip is missing, and these cams a re practically new. Iv a set of Popy cams where the exhaust cam has water damage. Im going to send it off anyways, i might as well send the 2 while im at it, where would you recommend Zed, there is nowhere here in Ireland..

That chip is nothing compared to the surface area of the rest of the lobe and if that's all that's wrong i'd save my money and run it.
As for the water damaged one that's another story and would need building up and regrinding.
I'd probably have a word with Phil Joy at Joy Engineering/Joy Cams at Bishop Stortford .
He's been making and reprofiling cams etc for donkey years and is well known.
There's also Kent Cams at Folkstone and plenty of others around if you do a Google search.

Thank you once again Zed1015 iv not heard of Phil Joy before but if you tip your hat his way then as far as im concerned its gospel, if i cant get him then Kent cams is where i was going to send them so all good, thanks again!
