1127cc camshaft differences!

[Tony H]

Hi. 

Are camshafts from the power screen GSX 1127 motor the same as the GSXR 1127 motor?

I was told by one OSS member they where by his part numbers but then told by another member they where not by his part numbers, so best check the part numbers yourself to get a 100% answer

And then, even if they are different, which is the better to use! Probably 2/10ths of FA difference, if any, in real world use LOL!

1127F same as 1052R i believe, so that will indeed make a difference

They stuck the same intake cams in everything except the bandits.

The exhaust cams were used in the powerscreen engines, slingshot 750s, and 1052s.

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.

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'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 day

 

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.

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

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 ? 

[Upshotknothole]

The list I posted is also for what's currently available still from Suzuki for sale. Suzuki being as cheap as they are, might have consolidated the cams down to just a few models to keep manufacturing as replacements. Only a guess.

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