Gsxr 1100 engine codes

[MikeyVeitch]

Hello again guys, I’m just wondering if any of the oil cooled engine gurus can help me with this one. I purchased an oil cooled gsxr engine and when it arrived, I don’t recognise the engine code. I know it’s an 1127 because of the cam chain and diaphragm clutch as well as the fact that I have stripped the head off and it is in fact a 78mm bore. So I guess my question is, does anyone recognise the engine code G0191-3861066

What is different about the cam chain? All 1100's (1052 and 1127) used std roller chains!  What does it say on the base of the barrels?

There is nothing written on the bottom of the barrels, I’ve been trying to sell the engine and everybody that looked at it can tell that it’s an 1100 but won’t take it because of the unknown engine code

Never seen that one before!

That can only mean one thing. Now you have to keep the engine and build a bike around it.

The first 5 digits are the engine code and In all the charts i,ve seen on Suzuki Engine Codes they have never used O 

Post some pics of the engine and the no.....

When you remove the clutch cover and look underneath where the engine number is stamped, is there any evidence of tampering? Grinding down an old number and then stamping a new one clearly requires force applied to metal thinner than it was before.
