slabside engine swap

[Crazylien]

my slabside engine did some damage after an oilpump failure now i would swap her out for an younger 1127 , still my slabside engine has all new gearbox and new barnet clutch and springs , would this fit an 1127 engine ? and would it for at first be possible to let her run on my 33mm flatsides . with proper jetting of course ...  are there any other problems i might run into ?

What slabby,750 or 1100?
And do you mean the slabby 750 VM29ss flatslides(they are only 33mm on the outlet,they are 29mm on the intake)?

i'ts an slabside 750 but she had the hop up kit from suzuki . so rev limiter was disabled , she has slotted cam sprockets the special pistons and the real stuf 33 mm carbu's

Mine is a GSXR750F frame with an 1127 motor... easy enough to swap but rear upper engine mount is a different diameter bolt. Mine also runs the VM29s but bored out to 33mm and it works OK just runs out of puff a bit top end..

You will need a different exhaust as the 1127 is taller

The slabby 750 and 1127 clutches are not interchangeable.. IIRC

[Crazylien]

not even when i the 750 gearbox axle ?

I don't think that's the case I'm sure that del ran a set of 750 downpipes on his 1100k and all he did was swamped the 1100k sump and oil pickup for a blandit one, I could be wrong though

Rear lower fixed mounting brackets are a different size  
11's are 12mm and 750's are 10mm. You can either take them out to 12mm or fit a copper sleeve inside the mount on the engine ,to take it down to 10mm

I knew it was one of them lol

[Captain Chaos]

don't slabby 1100's have a 10mm rear mount as well?

what I mean is all engine mounts are 10mm, except lower rear on 1127 and 1157 which is 12mm

Yep 1052 are 10mm and 1127/56 and 57 are 12mm.
Only know this because just put the powerscreen 1127 into Sonny's 1100g
