I know this is a Norton forum, but I thought you might like to see this, it's the 600cc Jawa outfit with the Neill Street motor:

They have a nice selection and also look to have the best prices in the business.

Just curious, I've got a 1971 750 motor, and the cam is marked "SS" :shock: Is this a hi performance Norton OEM cam ??? Perhaps i should use it in the 850 motor I'm building; opinions from all are invited ...
That sounds like a 2S- Combat cam. You can confirm that by measuring one intake and one exhaust lobe. They would be quite a bit different. The 2S cam is the only factory cam with considerably more lift on the intake than the exhaust. Jim
Well, your EXACTLY correct Jim. (still don't understand why Norton marked it "SS" ... but then "call" it a ... "2S" what kind of "pizzaro world" logic is that ??? :?
Anyway, it measures 1.263 and other is 1.261" for the the inner lobes; and measures 1.219" and 1.218" for the outer lobes. So the inner lobes are a bit larger as you say. Yes, quite different indeed.
It still puzzles me though, any thoughts on why Norton marked it "SS" ... but then call it a "2S" ??? :? BTW, this cam was in a 1974 850 motor I stripped :shock:
KHK said:I have a mega cycle 56020 SSS spare cam that had some damage on one lobe, kind of an oddball, I run it on my street norton, seems to come alive above 4500. Any interest Jim ?

SquareHead said:Jim,
Probably a stupid question (and I just had 2 pints of Guinness!), but do you only want cams that are Norton compatible? I assume that's the case, but if you are looking for other motorcycle cams, I may have a few laying around.
Thanks, and it's always enlightening to follow your threads. You have taught me quite a bit just by reading your threads.
Regards,
Chris
