ok all oil cooled heads with the exception of the 750 short stroke have no "dot" cast into them, the 750 short stroke is the only ones to have it (circled in red)

the long stroke heads won'd fit the 750 short stroke or 1100 motors, because of the area where the cam chain fits, if you like i can post a pick of what is diffrent.

the short stroke and 1100 heads are interchancable, however the combustion chamber on the 1100 is considerbly bigger and overhangs the gasket area on the 750, but the 750 head on the 1100 (1127) will lift compression (im not sure how much)

so basicly

two groups of oilcooled heads

1 1100's and shortstroke 750's

2 longstroke 750's and 600's

Now to confuse matters (i cant garentee this as i have not had the two next to each other)
but apparently the early 1100's (1052) and the late 1100's (1127) had diffrent heads as well

dot head IE oilcooled GSXR 750 shortstroke in red
standard IE oilcooled GSXR 750 longstroke in blue note the lack of the dot casting in the head


http://www.streetfighters.com.au/forum/upload/62381221786493.jpg


gasket is of a GSXR 750 shortstroke motor and the head is of an GSXR 750 longstroke motor, not the area circled in yellow, cam chain area is diffrent.

:D hope this helps clear up any questions as to the diffrences between the two.
The valves are also difrent sizes the shortstroke 750 has larger valves (same size as the 1127) where as the long stroke as smaller valves.

theres an alternative from gixxer.com
On the 1100 with compression set a point pump gas will work, you will not have a problem. Drag racers can run the head on big motors with 15-1 compression and not have problem because they allow the engine to cool between rounds. The second and most important reason the 1988-1989 head along with the 1989-1997Katana 750 head is so much better then the stock 1100 head is the ports are raised approx: .600 of an inch. This in effects gives ports more of straight/down-draft look at the back of the intake valve. Just think twice about trying to put Super Seats in a Slingshot head, they may fall out due to the reduced material between the seats.

I know of a GS engine which had a Slingshot head installed with stock GSXR1100 cams and made 152 horsepower at the counter shaft. No porting, no trick cams, just the differences in head design..
03 THIS HEAD HAS GOT 35,000K'S ON IT SO YOUR BETTER OFF TRYING TO GET A LOW K ONE THIS IS THE HEAD MENTIONED ON GIXXER

thanks but i need it for an shortstroke 750 which has dead valves it is head, i don't want to spend a lot on it as its only a eveyday hack and not that tidy.

putting the 1100 head on it looses too much compression so unfortuanily it realy need to be an 750 shortstroke head

DCRacing how did you go, can you help me out with one.

DCRacing
05-03-2009, 04:56 PM
well.......... i know for a fact that i have the required, the real problem is that i also have a 1056 that will be needing a head for it as the head that came with it has a fair bit of damage.....
so after saying all that i do need the cash......
can i think on it for a while clive? I am trying to balance a few things to get it all sorted out.......

actually have a talk to Devo, he was chasing a complete motor for someone. they had big issues in the gearbox, adn where looking for a complete replacement motor...... so you might be able to get one of him, or a complete motor for not a lot cash maybe.....

03, THE GIXXER ARTICLE TALKS ABOUT USING A 750 KATANA HEAD FROM 89-97-SAME AS DOT HEAD

TurboKat
05-03-2009, 10:12 PM
Isn't the Teapot (GSX 750 F) called the Katana (shudders) in some markets? If it is, I'd be surprised if it had the good head.

03gixxerpilot
06-03-2009, 12:50 AM
yes the gsxf 750 heads are also dot heads as the gsxf are shortstroke motors

TurboKat
06-03-2009, 10:06 AM
Chopa wrecked a Teapot motor recently, maybe he still has the head?

that's ok mate was just curious as understand the cams/dot head are not a bad improvement but just wasn't sure if the teapot cams would be as agressive as the gixxer ones

katana's cams are tiny compared to gsxr

i'm pretty sure that i have a complete motor, i'll double check before i go to work tomorrow.

Sorry Clive, I reassesd the head thing and i am going to need it sooner or later and it would only put me in your situation......... I thought about trying to rebuild the damaged head but the dollars i would have put into would not be worth it. Sorry to muck you around.

09-03-2009, 11:02 PM
LOL DC that is OK mate i know of a compleat longstroke motor that i might be able to get for a decent price, i think that it will be cheaper in the longrun. it is for a customer and i dont think he will mind.

Clive,

Check out this listing. Reckons they are out of a 89 that spun a bearing. might be in the market to part out the complete motor. Won't hurt to check.

Did those parts arrive ok?

Can you run a teapot head on an oil burner block?
Can someone put up a pic of the differences in the intake ports?
I would not mind trying to find a dot head at some stage to put on my early 1100 engine.
Is there some other way to get the performance of the dot head by modifying a 1052 head?

Cheers

Not now that you have let the critter from the bag :) At last someone that know`s what clay look`s like.Some claim that the 'Blandit' head is the go [|)] I dunno [:X] Anyway '03' if ya can get the cam`s from a 91 750 that`s my tip ;) if not try the 88 750 inlet mated to the 1100 exh.IF you are to big bore it make sure the pistons match the 'CC'.On a quiet note [8D] dispence of the 'tscc' & make it a single hemisphere.I know if defeats your search but is what I learned [:o)]
