Show and Tell: First Project is Ready for the Road!

Hello all. After lurking here for a while, I figure it is finally time that I introduce myself and do some show and tell on my own project. I've been wanting to start something like this for a while now, and back in November I picked up a 1983 R80RT from a fellow inmate not too far from where I live just north of Dallas.



Bike the night I brought it home




Before I go on, If you're looking for an RT restoration, you will be disappointed. It may look like sacrilege to some purists, but the reality is that this bike was most likely going to be parted out if I didn't take it. This way, I got the perfect base for my first project, and I still have all the parts that I will hopefully make their way to someone who is trying to restore their RT.


Mechanically, the bike was in very good condition. The engine runs solid, everything on it works and has, in my opinion, minimal corrosion for a bike that is almost 30 years old. So far, I haven't done much to the engine other than changing the fluids and cleaning it up. The bodywork is a different story. It was certainly serviceable, but that picture makes it look in much better shape than it was.



The goal for now as been to drop weight, and give it a sportier stance without throwing too much cash into it. Still have some little loose ends to tie up, but for now "Stage 1" is complete. The bike is road worthy and I plan on riding the snot out of it.





On to the good stuff, pictures:











A coworker snagged a couple of pics of me during a recent morning commute

Work that has been done:
1. Remove the body work and general clean up. Nothing to crazy here. Bottle of simple green, several rolls of shop towels, and scotchbrite pads got it cleaned up pretty well while still leaving a bit of "patina". I did end up using easy off to clean the wheels of some grime that wouldn't budge.


2. The headlamp needed new paint. Tore out all the wires, cleaned it up and used some black Rustoleum Textured on it. I like the way it turned out. Redoing the wiring was miserable though. Relocated the Ignition switch to the Headlamp mount and modified some universal style brackets to attach everything to the forks.


3. Installed some clip-ons from Woodcraft. Required a little reaming of the current controls to get them to fit. Nothing too difficult, I just took a wooden dowel rod and wrapped some sandpaper around it. Took a little bit of elbow grease, but they fit now.


4. Created some spacers to drop the instrument cluster down. I thought about fabricating a new bracket, but this was simpler and it turned out to work perfectly. Probably going to move to an Acewell unit in the future anyways.


5. Modified the subframe to accept a motoLana seat unit.


6. LED Bar end Turn signals up front, and LED brake light and turn signals out back. Made some brackets out back to position everything as I liked. Spent a couple of nights working out kinks in the wiring, but it turned out pretty clean.


7. The gas cap lock was broken, and at some point one of the POs filled in the gap with what looked like some sort of caulk. Tore it apart to clean it up and machined a black delrin plastic cap for the hole. If somebody really wants to steal my gas they can just cut the lines running down from the tank anyways.


8. Modified (cut up) both the front and rear fenders.


9. Replaced the old rotted tires with some Avon Road Riders


10. the old horns were shot, replaced them with some universal ones from Dime City Cycles


11. I removed the airbox (don't hate!) and added pods in anticipation of replacing the big heavy battery with a smaller one in that cavity. I ran it for about a week with just a Filter on the crankcase breather and was seeing more oil mist than I would like, so I ended up making a Catchcan out of a Flask I had laying around. The dimensions ended up working perfectly.


I'm not worried much about the pods. This is only going to be ridden in good weather and I doubt I'll be putting more than 2-3k miles on it in a year.


12. Installed some reverse cone mufflers. I love the way they sound. Loud, but not obnoxiously so (well... not too obnoxious). Needed to replace the crosspipes as the old ones had oxidized quite a bit and I ruined them trying to take the exhaust apart. Wrapped everything in tan exhaust wrap to hide the mismatching finishes. At some point I may give them a coat of high temp paint, but I don't mind the way they look now.


13. Stainless Steel Brake lines up front. They made a huge difference from the stock rubber hose that was on there.

Other upgrades that I'd like to do



1. Some new rear shocks are high on the priority list right now


2. I should probably upgrade the front shocks (internals) as well.


3. I want to change to a smaller battery, and move into old airbox space. Along with changing the rear fender to a hugger mounted on the swingarm, this should create a nice empty space under the seat.


4. I'm thinking of making a rear cowl cover whenever this whole thing gets a new coat of paint just to break up all the black in the back.


5. I don't find the stock pegs and clip-ons that uncomfortable, but will eventually install some rearsets


6. Acewell instrument cluster


7. cut down the steering damper control knob to something that is flush or close to the top triple tree (plate)


8. This sounds crazy, but at some point I think I may try to do a rewire on the whole bike. Move all the wiring out of the headlamp, and maybe take a shot at crafting something a little less traditional upfront.

Realized that one needs a fancy-pants ratcheting crimper with dies specifically for flag terminals

Crimper ordered.

Sigh.

Step 1. suspend heavy-ish item by wire.
Step 2. put two layers of paint on item
Step 3. while putting third layer on, watch in disbelief as wire comes undone and item drops onto ground into dirt and leaf litter.
Step 4. shake can vigorously and debate just painting over all of it, sticks, bugs, leaves, and all.

Nice job. How is the low end power with the shorty mufflers?

Thanks,

Low end power seems fine to me, but then again I don't have much to judge it against. I only took it for a short ride or two with the stock mufflers while it was still in RT form, and at that point significantly heavier. The weight change seems more noticable than anything. If I lost a bit of power, my riding skills aren't refined enough to notice.

Looks good. But lose the horn and the side reflectors.

Looking really tasty. Fair balls having a go at the tank like that! Reminds me of the 'cafe racer dreams' 2-tone tanks.

Any chance of a few close ups of your seat bracket, and how it fits on the frame? Is the seat the same with as the sub frame or would it drop in there?

The bikes from CRD are the inspiration for tank. Always liked the way they looked, and I think it helps slim down the bike.

I don't have any pics of the seat area right now, but I'll be sure to snap a few this week if I can. Unfortunately, the seat and subframe are the same width. I was hoping to be able hang the edge of the seat over the horizontal tubes of the subframe, but they won't fit over. I tried to match the lines as best I could. Its not perfect, but I'm happy with how it turned out. I had to find a medium between the lines of the subframe, and a comfortable angle for the seat.

I've given some thought to fabricating a new subframe, but I figured it could wait as I take care of some other stuff. I've had a bunch of people ask how long it took me to "finish" the bike. I just laugh saying that I don't think it will every be "finished", but it is rideable...

As much as it pains me to say it (I'm a stock-wiring-loom-color-scheme-as-BMW-intended purist), I like this bike.

If it were my project, I'd next black out the engine and possible add some trick shocks for the rear (with reservoir, comp/rebound adjustments).

But I wouldn't be ashamed to sit on that one as it is, nice work.

Thanks ignatz! I've had a blast working on the bike. This is my first real project. I've had a lot of inspiration from the other builds on Old's Cool, especially Miob's build (as i'm sure many other have as well). As you can tell, I'm not much of a as BMW purist myself, but tend to really enjoy taking a project and throwing my own spin on to it.

New rear shocks are on the shortlist of mods that I'd like to add soon. I just started looking into them, and it appears that I'll need to save up a little more. Wasn't quite prepared for the cost of a good pair (almost as much as I spent to purchase the bike), and I'd rather save up for some good ones, than buy a cheaper pair just to put them on there.

Other than that I'm looking to put on some rearsets and a machined upper triple clamp. I'm torn between just purchasing the rearsets from Boxer Metal or having a go at making my own. Some time this winter I'm going to tear her down and clean up the frame by cutting off the extra tabs and refinishing it. Also going to paint or powder coat the wheels. Probably give the engine a coat while I'm at it too.
