Woo Hoo! A Big Project!

How was the powdercoating to work with when lacing the rims? Did you have to drill all the holes?

Yes I did. Not too tough, just had to be careful of the bit slipping out and gouging the PC on the hub.

And we now learn more about you. You are between 5'9" and 5'11".

In my powdercoat shop, (it's not really mine, I just act like I own it) we have a huge assortment of plugs and caps to avoid filling holes with powder. I'm sure we have thin spoke sized ones.

They're some type of silicone/rubber that doesn't melt in the oven and nothing sticks to them.

Not too far off--actually a little shorter, but track bikes, and this one in particular, have higher BBs so the head tube is just a wee spot longer than you might expect. Also the axle to crown on the fork is shortish with that crown.

This one has a lower BB and a taller fork (I bought it from Jeana 22 years ago):

Yeah, just picked up the lever perches from PC yesterday and pulled out a few rubber corks from the several threaded holes. They had them down to 2mm. If'n I ever do this again, I'll have them plug the spoke holes.

And the current difficulty. When I took it apart, the wires to the starter relay were all the same color, coppery greenish from the corrosion due to the leaky MC. I figured I'd clean them up and, with my fabulous Haynes wiring diagram, match them up to the DIN numbers on the bottom of the relay. That was before I found that a /6 relay has no DIN numbers on it! Can anyone help me out with what goes where in this picture? Wire color, wire source, or which DIN applies to which spade are all fine.



Perspective is as if the relay was unbolted from the frame and tilted up.

Rob F probably knows these by heart, but I haven't seen him around much.
Don't trust any of the wiring diagrams, even the official BMW ones.
I've seen errors in the starter relay circuits in a few of them that led to A LOT of head scratching.
There were also a few wiring/relay changes over the years before they eliminated this type of relay altogether.

Your best bet is if a forum member with a SAME YEAR bike could post a few close ups of his relay and wires..

sorry I can't help you with this one.

This link should go to an Airheads Tech article. It has all of the BMW relays with terminal numbers.

Starter relay B about a third of the way down that links page?
