what is compatable between 700e and 750e?

[frozenfish66]

im looking into buying a 1985 gs700e i want to know what parts are compatable between it and a 750?

[Nessism]

Most everything except for a few engine parts, assuming you are talking about the 3rd generation 750.

[frozenfish66]

so carb parts shouldent be a problem to find then. thanks

The only difference between the two is rods, crank, and exhaust cam. Some people claim the pistons are different but I've always seen the same part number for the two. The 700 cam used to be a popular mod for the 750. The bodywork is slightly different too. The carb jetting differs a little too.

The biggest difference is the 700's are faster especially the blue ones...

Early production 700's had different pistons, And the part that holds the shock bellcrank (fits in the middle of the swingarm) and the part between the bellcrank and swingarm is different also. And the 700's have a longer (about 1/2 an inch) swingarm.

Good info Dee. Mine was produced in October of '84. I wonder if that makes it one of the early ones?

Here's a picure of that:

Left is the 83 750. Right is my 85 750.The 83 is lighter so that went in the 85.

My 700 has the earlier part so I suppose I might also have the higher compression pistons.

Found the Canadian 85 750 has different triples than the 83.Don't know if the 700 is the same.

Hey Billy, I'm gonna try a set of 700 pistons(slight dome) with750 rods and crank. I'm also going to use the 700 gearbox, and 700 cams.

I hope it all works cause it's all the good parts I have left between the two parts bikes I have....Have you tried this combo before?

Guess I got lucky then - my own project 700 is a blue one...

How has this gone so far? I have an 85' 700 with +60k on it. gonna swap in some good used pistons/cylinders that still have hone marks. but it might have an ailing rod bearing. If thats the case then the motor is coming apart. But instead of new bearings, a cheap bastard route would be to pick up another crank and rods off ebay for $50 and put them in.
I got my bike at a tow auction for $200 so my plan is to stay cheap. Of course, I just found out my towing company impounded an 82 gs1100e. So i'm thinking of doing a 7/11 on it. decisions... decisions...

That motor will not fit into your frame, without extensive frame modifications.

You need an '80-'82 GS750E to do a 7/11 mod.

I thought I had read that on here somewhere before !!
