Teapot DOT Head?

[nightrider]

Happily traded some Flying H crap for some superior parts and lumps from the local Flying H guy.

One of the lumps was marked as an 89 GSX750. On closer inspection it has a DOT head.

Hurray I says.

However there isn't any gray paint under the black paint. Is there such a thing as a Teapot DOT?

[Captain Chaos]

yes, 1st gen T-pot 750 (till '98) has a Dothead. Basically the same engine as the GSX-R 750 J/K.

Clutch operation on right side means GSX-R, on left side means Teapot.

[Rene EFE]

Yes

[Neill666]

I have a spare teapot 750 motor and yup it has a dot head 

[nightrider]

Thanks m8s!

Been looking forever for one of these. I was very eager to make that trade

Three heads, 5 stators w/ rotors and three air boxes for a DOT engine, a 750es engine, 750w rear wheel, 1150es front suspension, an 1100e head w/ cams and valves.

Not too shabby......

I've got one sat on the floor in the workshop waiting to go in my GS 750

Iv got a teapot DOT head on my Bandit 1200 Harris build.

Is the DOT head only on the short stroke engines?

[Captain Chaos]

yes

Are Teapot and GSXR Dot Head valve sizes the same? And...are the inlet tracts on both inclined the same, or Teapot less so?

the dot head has a smaller chamber but the same size valves as the 1100...and the inlet tract is steeper

Well now that's interesting

[Swirl]

would you see an improvement with a teapot dot head a bandit 12 lump, or is it only the gsxr dot head any good

Marginally as it raises the C/R

Yes, But you will need to use 750 K or 1100 K cams to get the most out of it. Teapot cams are a softer profile.

I'll let you know! My teapot DOT is going on my K4 Bandit. Incidentally, it seems even teapot cams are higher lift than what the Mk2 Bandit uses.

I've fitted a rodger. Uppteron dot head to b12 bottom end, with Gsxr k cams made 148bhp. With 94lbs torque! Lively beast for feck all cash, I skimmed the dot head by 0.005" too with dailed in cams made huge punch. 

You will love it cheap hp.

Yoshi john was after one in the wanted section

Did you use the teapot cams or the bandits?

Hi @SiBagwhat Harris frame have you got ? Thinking of going DOT head on a rebuild GSXr1100 engine to go in a Mag 4 frame but a bit worried the angle of the DOT inlet and position of carbs will not fit. Did yours fit OK ? Do you have a build thread on here for your bike ? Had a look but couldn't find anything. cheers

As has been mentioned in a couple of threads 750 j/k inlet rubbers an carb tops (36mm) are shorter but appear to be rocking horse approaching unicorn poop....
