Working on the GPz305

On Wednesday I started working on the Kawasaki GPz305. It’s a cute little bike, but it’s been abused a bit.

I needed to replace the headlight, the battery and change the oil. I also decided that I would add a headlight relay to try and get some more light out of it.

So I spent two hours wiring up the relay only to discover that I had made a fundimental error. To properly relay the headlight, you need two relays. I had wired it with one relay and the low beam was on even when the bike was off. 🙁

Luckily I had two relays available and on Thursday I fixed it up the right way. It works great. The old headlight, which was a weird 40/55W bulb was like holding a candle out in front of the bike. I stuck in a standard 55/60W bulb and with the new 12ga wires straight to the battery it is BRIGHT!

I changed the oil, stuck in the new battery and took it for a spin. What a silly little bike.

I rode it to work this morning. Man that thing is tiny. But it’s got plenty of get up and go.

It still needs some work. It’s got a turn signal that doesn’t work and the carbs are still a little wonkey. I’m going to run a can of Sea Foam through it and see if that makes it better.
