Should this cam be replaced?
This is the intake lobe for cylinder #3.

They are beyond dead, but how did the rust get on those inside your engine????

My guess is the rusting occurred when the PO let it sit for a year without starting it.
Unless I can find a set of cams for the 750 CHEAP, I may be parting the bike out soon. Not worth spending as much to get the bike running as I did for the bike itself.Last edited by wcj; 01-12-2008, 01:07 PM.Comment

Well, got the cam out and it doesnt look so bad now.
This is the same lobe wiped off with a shop rag.Comment

I don't know dude. It's iffy, you could get away with using it, but I'd look to swap.

Well, I decided to put it back in and see what it looks like after 1000 miles.Comment

Looking at that cam, from the experience I've been thru with my own. Thats not bad looking at all. You are only showing minor spots which arent a problem. I would put those back in the bike. Since you have pictures of what it looks like presently, in 7,500 miles, when you do the valve adjustment, compare then to now.
If you had scoring where the steels rolled on the lobe, then I would say its time to shop for new ones. Heres a pic from one I replaced in mine.
If its not broke, Hit it with a bigger hammer and blame it on cheap imports

i would not run it, its right on the edge of where the lifter runs, its already week from the rust pitting it will only get worse
also why risk having a cam go flat and having all that metal go through your engine and causing more damage, possibly a new engineComment

The pitting shown wasn't due to rust. Suzuki had an issue with certian pre 750 cams where the hardness flakes from the cam. It doesnt affect all cams and its impossible to know if yours has this without watching it. The hardened band didn't properly bond to the rough cast.
However since there is no scoring, The marks may have been there from day one. He can consider the cams to be OK for now. WJC knows to monitor it since he posted he will check it in another 1000 miles and should agian at the next valve adjust.If its not broke, Hit it with a bigger hammer and blame it on cheap imports

The edges don't really matter -- it's only the center, although the edges do point this cam out as being one of the defective ones IMHO.Originally posted by arsenic1016 View PostI don't know dude. It's iffy, you could get away with using it, but I'd look to swap.
The minor pitting in the center is annoying and will probably spread (check the valve stems too), but not enough to keep you from riding it until you can get a replacement, again IMHO.
