'91 1100 cams in a GSX750F?

[scott-s]

 Since the old school '86-90 GSXR cams seem so hard to find these days, I've found a set of '91 Katana (Teapot? What the hell am I supposed to call this thing?) 1100 cams for pretty cheap. I can get them for $50 o 60 U.S.

 

It's my understanding that the '91 1100 IN and EX cams are the same as the 88-89 GSXR 750 IN cam and 1988 GSXR 750 EX cam. It looks like the 1100 cams would give me an extra ~1.2mm of lift on both the IN and EX. Nor sure about the duration.

 

 I will be running stock Teapot head and valves, compression ratio, etc. I have the stock 750 header and a Yoshimura pipe/muffler. I have the BST-36 carbs, a DynoJet stage 3 kit, RamAir filters over stock rubber velocity stacks. I also plan on slotting the timing plate to advance the timing.

 

 Are the '91 1100 cams the ones I want for a '00 Teapot 750? Is it worth my time and ~$60 to do it, with the above mods? I've read that tuning the carbs will be easier with the hotter cams.

Psssst - Read rule #5.................I didn't make them ! ! !

 Well, that's why I always try to refer to my 2000 as either a Teapot or GSX750F.

 Was the '91 1100 uh, whatever it's called, referred to as something else? Should I refer to it as a teapot, too?

 

 Sorry, I'm a Yank and I just don't know all the proper English slang terms.

 Anyway, I edited the title and post. But....what about those cams?

the GSX1100F is commonly known as the Powerscreen, because of the electric adjustable windscreen.

About the camshafts I have no idea.

I love those cams, lots of bottom end & top end power. If you are meaning gsx 1100f ones.

[scott-s]

 They're from a '91 1100, commonly referred to by the "K" word over here in the states.

 

 It's my understanding that they're basically the same names that were in the early GSXR 750, and those cams are the "hotter" cams for the Teapot 750.

 Just hoping for some clarification.  I can install and time them myself, so if they're worth doing for ~$60, I'd give them a try.

What ever cams you use check the thrust faces are the same. When I converted my M head to screw and lock nut I had to get head welded then I re machined.

Also check lift so coil bind of the springs and make they don't bottom out on the guide.

This really not answered your question really but hopefully tells you what to check.

Doesn't a '00 teapot have a smaller (non DOT) early style (slabby) cylinder head? If so those cams wouldn't fit....

 Is it OK to link to other sites? I can show you where I found the information and maybe you guys can shed some light on whether or not I'm looking for the correct parts.

[scott-s]

 Hope this is OK. Here's where I found the information about the GSXR 750 cams:

Okay, that clears it up, I wasn't sure if the camshafts them selves were all the same size or not. My bad....  

[scott-s]

 So you think they should? The '91 1100?

 

 With my combo listed about, is it worth my time and 60 bucks? Would I gain anything, other than a tuning headache?

[scott-s]

The 1100 cans got sold but I may have found some GSXR750 cams.

 So, back to the meat of the question: if the price is right is it worth doing?

 I've heard that it can actually make tuning the carbs with RamAir filters easier.  Something about the lazy Teapot cams and pods not playing well together but the lumpier GSXR cams giving a better "signal " or something?
