Hells Canyon, that's the plan. Only two weeks to go.

So a little update. The motor is a regular 650 motor and the Dyna ignition doesn't want to work with it, so I decided to use the ignition that came with the motor. That in turn means using all of the wiring that came with it too. So it's basically a 100% rewire. Fortunately the wiring I got is in excellent shape, and complete, so it will be a fairly easy job. I did about half of it in a day. Most of that was removing the old wiring and digging through the boxes to find the new parts. The only custom work I've done so far is modify the battery box to take the AGM battery that I have now. The stock 650 battery is an odd shape and there is no AGM that I could find that fit it. Having a spillable battery in a dirt bike is not appealing.

With Lady Bug's Hells Canyon Rally only a week away, Luke's begun thrashing in earnest.

Wiring harness nearly completed;


Luke fabricated a nifty bracket for the stock coil pack;


Rebuilt battery box and AGM battery can be seen nestled behind air cleaner;


Pipes going on, won't be long til she comes back to life;

Been following this build quietly... Would LOVE to have one of these someday... Nice work!

Awesome Luke! Also curious how the factory CB650 transmission ratios will compare with the CB650/550 hybrid gear-set...

I keep looking for Luke's IN on the Hells canyon thread. I have Loud Al's, Koote nai Rider's and even Orgeon coast's and Laura's.

Luke, it's your turn to post up.

Well, I was on the fence.... or not so much on the fence as in the shop. Now that the bike is running I'm IN.




So yes, I got it running today. The donor motor needed some work. It looked good on the outside but had been sitting with the carbs and exhaust off for who-knows-how-long, so I pulled the top end to make sure there wasn't any junk in there. There was. Nothing that had fallen in, but a whole lot of carbon build up. I think the bike was sucking oil from the breather. There were big oily flakes half-stuck to the pistons. After cleaning it up it looked good though, so I put it back together with a new head gasket. Set the valves, changed the oil (yuck), and fired it up. Everything seems to work ok, it runs well, shifts through the gears and the clutch works. There's a little more wiring to do to get the lights working with the new harness, but other than that it should be set.

Thanks!

If I can offer some advice:
1: Do it.
2: Start with a running bike.
