Fins to the Left, Fins to the Right

Took my new exhaust fin wrench out to the garage and tried it out on the left and right nuts. After spraying some deep creep into the groves, the nuts came right off, fresh antisieze paste looked like it had been applied recently.

Buffing up the rear

ith the tank off, and master cylinder getting repaired, I thought it might be a good idea to good ahead and paint the rear frame member, I have been lightly sanding areas where rust has been starting to show up.

I removed the seat, unbolted everything, and put pull strings through the rear frame tubes for the brake lighting.

It might be a good idea to go ahead and do a spline lube with everything off the rear, that will entail removing the swing arm, etc, which I do not have the right tools to do right now.

Rear Brake Lighting, just in case I forget

New Throttle Cables

Need to sync carbs, now that new throttle cables are on.

Master Issue

This weekend, found a pool of brake fluid dripping down the side of the bike, and discovered it was coming from the back of the master cylinder. I pulled the assembly and found some rusting on the outside of the plunger, and decided to pull it apart to inpect.

The inards did not look too bad, pull all the parts, plunger, spring, rubber gaskets, etc. I pulled the top resivour off, and unscrewd the brake switch.

There was some rust on the inside, so I soaked in 100% vinegar for two hours. This cleaned it up nice, and I soaked with thin oil to keep it from rusting again.

Cleaned up all the parts and re-assembled, re-installed, and bam no brake pressure. I will buy a rebuild kit as air seems to be seeping through at this point.

Here is the rebuild kit, $69.00

Starting to color her up

Will publish finished bike, plan on doing fenders and then tank, with new BMW emblems to replace torn ones. Should look half decent, I will put clear coat on as best as I can, no pin strips for now.

Rustroleum Black Enamel, easy to find and half decent for a Rat Bike.

New Fuel Line

I have had 3 feet of braided fuel line and fuel filters for a while, the older fuel line and the original fuel filters I installed early in the summer will be kept for emergencies, but for now, new line and filters.

Rear Wheel Cleaning and Lube

Decided to clean the rim on the rear wheel with Mothers aluminum cleaner, and check out the rear brake wear and spline condition. As expected, looks like the lube is hard and dried out.
