motor swap question

[makenzie71]

Working on a couple different ideas here but essentially I have a GS wiring harness and I'm wondering if I can slap in an EX650 or 500 or any other parallel twin in there and make it work?  I can't find anything different enough between any of the engines to say that the ahrnesses won't swap around without a problem...trying to find out if anyone knows something about it I don't.

ohh man that would be a mean little gs with a  650 in it......let me know if you figure out how to do it........

It's actually going to go into an Avanti R2..a little more aggressive stance than a GS and about 100lbs lighter.

better off with a kaw harness if you are using a kaw engine.

puters are probably different along with associated pickups
coils probably different

kaw is watercooled and has extra wires for temp sensor, temp switch, and fan

why work 7 times as hard to get it to work?

[makenzie71]

The biggest reason for making it work is that I want to use the 650 block and I can get one cheap, but I'm not interested in EFI, much less piecing it together individually.

the gs w/ ex500 motor is common in cali they call em gsex's was going to do one pretty simple actually-one rear motor mnt even works.just rig a rad mnt and linkage shifter and your there.

you can get a main wire harness for an ex500 on e-bay for about $65

Find me an EX650 harness, with the ECU, for $65.
