EFE engine into 750 Et frame

[Not_so_Evil_Lloyd]

Whats the deal with motor mounts for an efe motor into a 750et frame. Can i use ET mounts or do i need to make new ones?

Anyone? 

The reason i'm asking is i have just purchased this 750 ET frame with braced arm and monoshock conversion of a well known auction site. It's sat in the UK atm at a friends and i won't be picking it up until the zombie virus has gone away. So while it's over there i could get it blasted and powder coated at half the cost it would be over here but i don't want to do that if i then have to start messing with it to get me EFE engine in.

I think you need to drill the rear engine plates bigger from 10mm to 12mm .

As the other engine plates are bolt-on i wouldn't worry.

 

Others will know for sure. Never did this conversion myself.

I can’t remember fully, but I’m sure it was just the bottom rail mounts that I changed, I used a mix of et/efe mounts for the rest.

Thanks guys. If there's a possibility i have to alter mounts i'll wait till i can get it onto alchotraz to have it done.

I've fitted an EFE engine in my fake Katana that is built around a GSX750EX frame. Although I modded a lot of stuff on that frame I'm pretty sure the EFE lump should drop into a stock frame easily using the original mounting plates give or take a few washers as spacers here and there.
Just the front bottom mounts need custom plates on 750 frames alone fitting 1100 engines because of the  different position mounting holes on the GSX750 engines.

Make these plates after (test) fitting the engine. Templates are easily made by offering up a piece of cardboard and punching holes with a pencil where the bolts should go.
On some engine-frame combo's the engine just hits one of these threaded bolt holes bushes on the frame, and some grinding (1 mm) is needed to provide the necessary relief and allow proper lining up of the other holes/mounts.

yes, new engine bottom mounts required, swingarm spindle hole is also a bit weedy, and the 750 frame doesn't have the cross member in the front, by the exhaust headers, which I would definitely benefit from with an efe motor in it. 

bit of frame bracing always helps too.
