PGK's beemer with a big update!

flash back to 1981. BMW decides it's time for something completely different, and make this:

The R80GS, and create a new niche within motorcycling. A year gets on, and they decide to create a niche within a niche with this:

The R80ST. it's a GS with a smaller wheel, more tasteful paint, and shorter, narrower bars, a tachometer, and a few other things that make it a more useful streetbike. Back then they called bikes like it 'scramblers' now we would call them 'supermotos'. Either way, no one buys it, less than 6000 are made and 980 are imported to the US. Most of them sit. Then along comes my dad, and buys one, brand new. First vehicle he bought new, only bike he had until he bought his R1100S in 2004. He puts 130,000 miles on it. The first 100,000 are entirely city miles--he trained motorcycle couriers in DC with it. He keeps riding it after he's through with that, and gets almost $15,000 worth of work done to it over its lifetime. He then hands it down to me. I beat the crap out of it and last may I blew it up. Scored the crankshaft, and destroyed the rod bearings.

It got taken down and put into storage at my parents place, with the intention of doing a total restoration, eventually. Eventually gave way to right now, due to impatience, which brings me here. I got a new crank, as you can see in the pic. So this morning I head out to my parents, and load up the car.

Drive to work, and unload, and get started.


The goal for the day was to put together the rolling chassis and ancillaries, bleed the front brake, order seal kit for the motor, and clean/inspect motor parts in preparation for the rebuild.

progress. Installed bars from an R1150R Rockster. kinda a cross between drag and superbike bars, a slight rise and very wide.

headlight/wiring harness/tank etc all on. Really, not much to installing the tank. it's held on with a metal ring that loops around the frame spine. also, i dented it in a crash.

nu shooz!
and now, for the motor:

that's pretty much it. these motors only have 8 or 9 parts.

combustion chamber. Valves, seats, and guides were all in immaculate condition. CC products guides, valves, and seats, along with valve spring shimming was done in '93 or '95. not much to see, but i decided to do a mexican valve job anyways. after:

pretty.

about that time i got tired. and went home. more to come later, as parts arrive/shit gets done.
