The seat looks great.

Make sure to check your wiring to the coils and move the wires as you test to make sure there are no internal breaks in the wires.

Thanks man!

I replaced the harness but not the little wires on the coils. When it started missing I also lost my tach. I'm tied into yellow wire for tach reference.

Sounds more like a loose power or ground connection than a bad coil/igntion plate.

It was a faulting pickup on one side of the Dyna-s ignition. I replaced it with another used Dyna-s and all is well.

This project bike is completed. I need to take it out somewhere scenic and get some glamour shots.

It seems these types of bikes are never quite complete...

So the bike has gotten some upgrades lately. I replaced the head with a ported and done up for race unit. The other head was having some issues with exhaust valve guides and burning oil. I also threw on a set of PD42 carbs with new cables and pods. The carbs were jetted with 42/130 jets and a .020" shim on the needle. Its a little fat up top right now. Haven't had the motivation to put the 125 or 128 main jets in.

Otherwise, the bike runs quite well now. It will only get better with more carb tuning. I also installed a cam that was slightly used and stamped CRANE H284.

I took it for a ride the other day and my buddy hopped on for a spin around the block. Thought I might take a few pics out in the sunlight.

Cheers guys!

Thanks for the kind words. I need to ride it more now that it is done.

Here's a quick video for anyone interested in some noise!
