GS250 engine

[matticus66]

I just picked up what I was told was a gs450 engine, but I'm pretty sure it's a 250. Anyway the wiring harness is pretty much in pieces and I was wondering if someone has the diagram for it? I know I have the coils but I'm not sure about the voltage regulator/cdi box. I dont need lights or signals as this is going in an offroad vehicle, I just really need the electrics to start up the bike.


Thanks,
Matt

Should have the size stamped on it in the front somewhere. A site with wiring schematics on it has been posted a few times around here. I can't remember it off the top of my head though, see if a search pulls anything up.

My '81 GS450 has - "GS450 - XXXXX" stamped into the right hand side of the motor (where XXXX is the serial number).

Engine capacity is usually cast in the cylinders somewhere too.

Was there a GS 250? Weren't the only 250's GT's?

Yep! didn't/doesn't Queenie have one now? Think they may have only come to the US two years...

yup, it's a gs250, not sure about the GT or anything. It says gs25x on the side and 249cm3 on the front, took me alot of cleaning to see that. The whole engine is pretty nice looking on the inside, so hopefully after I get a cdi and the wiring figured out I can shoved it in a minibike or go kart.

Gs/gsx250

Matt,
I used to have one of those 250s a long time ago and I still have a manual for it somewhere with the wiring diagram. I'll try to scan it and send it on if you need it. Let me know.

Here is a thread we had up on manuals. It lists a GS250 FWS. I don't know if that is the same bike.

will work, I'm kinda new to motorcycle engines, is the signal generator the thing under the right side cover?

It should be on the right end of the crank under the cover.

Yes Queenie has two! the capacity is stamped into the cylinder block below the exhaust ports on the left hand side.
