1100 ET engine in ’83 750 EF frame?

[HerbaKanki]

Sorry if it has been asked before, but couldnt find an answer. I have spare 1100 et engine, and was offered 750 ef frame. So will it fit, and if not, is it worth making it fit?

Anything will fit, just how much work there is to do it 

But to your question, no.

The 750ef engine's are much smaller than the 1100 engines in most if not all dimensions most front to back, so you would have to do some stretching of the frame.

Is it worth it, that's down to you, I'd say no. Get a oil cooled motor put that in the 750ef frame then get a other GS or gsx frame for the 1100 

[HerbaKanki]

Thanks for the reply! It was as I expected. I see wisdom in Wraiths words in oil cooled ways, but I think I’m going the hard way anyway! Besides my oilboilers are needed in other projects…

So I will make it fit.

my mate fitted a B12 motor into a 400 katana frame, yeah he had to modify the frame a bit 

 

[Poldark]

He did a great job; I bet it's crazy quick.

[Muddy]

Wow, that looks very nice indeed. 

[gsxwill]

Nice job, bet that's fun to ride

he has way too many bikes but the Kat is one of his fav's
