So there's a slight difference with the cams, but not much.

Very interesting.  Taking this a step further. How do the powerscreen cams compare to Bandit 1200.

Reason for asking is I have a knackered inlet cam on a Bandit motor. Spare Powerscreen cams on the bench ready to go in. However I can pinch some GSXR cams sat in a spare motor but that's more work.

I've been reading just that topic on my french gsxr forum. A couple of guys confirm that F cams on b12 fit and make for a nice beefy increase

750 J/K dot head inlet cams are 12711-06B03

750 slabby 86/87 are 12711-28A00

according to the parts fiche.??

 

check the right hand end and read off the stamped letter.. i measured a load a few years back when I was bored one dayO.o

 

The B's came from a 88 750 gsxr, N's from a b12  the g from a 1100 teapot and the s from a 750 teapot I think It was 10 years ago so memory might have failed me.. 

Best cams fro a b12 ive found are gsxr J/K  750 Dot heads cams.:tu

Re the above chart - I thought the 600's had a different cylinder spacing to the 750 / 1100 engines?

So how would the camshafts interchange?

I hope not xD I'm going to be putting 750 block and pistons on a b6 bottom end in the next year O.o

There was a old wright up in streetfighters mag some years ago (is it still going?) With one of there team putting a 750 top end in a b6 with the 884cc big bore etc and they said it made more bhp than a standard gsxr1100 

But you must think as price of parts and trying to find some parts, is it just worth getting a 750 motor ?

I like 1100 powerscreen cams I have used them in 2 turbo bikes
