A buddy of mine sent me this pic of his preowned TC88 which was upgraded with hydraulic tensioners by the first owner. His question: Can you please tell me what cam it is? :nix:
Looks like a stock B cam. It is usually stamped on the other side. Pic is blurry when I zoom in though. A = carburetor B= fuel injection, or the other way around, been a while.
If the bike has had the hydraulic conversion done using the roller chain then the bike is 1999 to 2006 and those cams can't be the originals.
Probably one of the Andrews Conversion cams.
The internet seems to think the markings that identify the cams are on the inside.
Bit of a pain if it is true!
Try measuring the lift.
They are stock cams. I am on my pc now not my phone and can see the pic better. You can run stock cams with the screaming eagle conversion, I have installed many. Hope that helps.

If he used the Screamin' Chicken cam plate they can be stockers. They have ball bearings on the outer so for sure it is a SE cam plate and "style style" cams.

Ah. You can just see 'Scr' in the picture, I thought the official HD conversion included new cams too...
Crap!
and "style style" cams
"stock style" cams!
Thanks so far guys! I still doubt that we see a stock cam. Stockers don't show any marks on the outer face imho.

I have a pile of stock Harley cams, i have one with identical marks.
That's the old model SE cam plate. It still has a silent chain with a hydrolic tensioner on the back and that tensioner should be checked for wear (the silent chain ate hydrolic tensioners too). If you pull the plate to check the tensioner shoe, you'll know for certain what cam you're dealing with, and have one less wear item to worry about... win-win and you're already most of the way there based on this picture.
Seen a thousand of them. Those are stock HD cams.

IIRC, from what I have been led to believe here, that update is holding up well.
I don't know anybody that looses sleep over it, but it is a wear item and an excuse to pull the plate, and check to see if the inner bearings were replaced too. If it's a stock cam I just found this on eBay!

That'd bold in most 88 applications real well ;)
They say used, "dyno time". They sure look like they've been polished to try and clean them up. Look at the sprockets.
Thanks alot guys. I'm convinced now these cams are stock :SM:

Unless they were reground... :potstir:
