Hi guys. I’ve got myself a gpz 500 trike but I’m struggling with spark. I don’t really want a full complicated loom for off-road. I’m needing someone who knows about the wiring and can help me creat a simplified loom. I can’t find anything for the gpz. I had already made a race loom for an ex500 but that had 2 magnetos where as the gpz only has one. Even if someone knows what wires do what on the ignition box I could then creat my own custom loom. Only thing I could find was for a 250. Thanks.

Hullo Stephen, wylcome to Ninjette!! :wave:

You have early 1st-gen 500 with single pickup coil. You can find wiring diagram for it by doing Google for "classic early gpz500 wiring diagram". There's hit on classic site with DIR_1667004 which contains PDF.

Then go to this thread where people posted their own minimal diagrams.

Now thats how you answer a technical question! Salute!

How can you post about an off road GPZ500 powered trike and not give us pictures?

Or ask a question and then not come back for two weeks. I hope he's not sick.

Apologies. Never though about pictures. In a rough state but you’ll get the idea. It’s a little narrow though but thats the way I bought it.

I don’t really post on online forums so I always forget to check them. Lol.

Wow, that is narrow and tall. Narrow and a high center of gravity is not a good combination. Take it easy when riding off road.

Once it’s up and running I’m going to look at getting a longer swing arm and a wider axle for it. Should be a good bit of fun though.

That's pretty darn cool!

What frame are you using?

From what I know it’s a j reg ex500 which has been powder coated. . Engine had no compression so now trying to get the replacement gpz engine running to go into it.
