86 gs750 es motor VS 83 gs750 e motor

[Anonymous]

Hi I just picked up a partsbike (86) 750 es.
On the few sales broschures here on the web I've seen that they claim 91hp.Does anyone know what would be different between the 83 750 e, I have and the 86/750es?
I'm guessing different cams on it.
If anyone has any idea let me know.
My plan is to swap engines since mine has allmost 56000km on it,the only thing I know of being wrong to my 83 is a slipping clutch.

I posted this message before but I edited it to see If I would get some response to it

Cam timing and maybe 700 pistons. Do you know the compression on the 91 hp engine?

My guess would be a numbers game. Power numbers can differ depending on where the power is measured at. I would not expect any change for the 86 GS as Suzuki was heavily involved with the GSXR750 starting in 85- with both R+D and advertising, so there would be no real benefit from tweaking the 750ES as the model was already outdated and replaced.
