Thanks, guys!
I did most of the labor by myself, and it was a great learning process. I'm lucky that here in Portland Steve Prokop, arguably the best BMW mechanic on the West Coast and amazing human being lives just outside of town. Also, Jeff Truhn is right around the corner and he specializes in BMW restoration. He hooked me up with and rebuilt my five speed gear box. I've owned the bike since 2000. At first I just repaired the bike as necessary, but at some point I decided to just tear it all down and go for it. Most of the parts came from Eurotech, Rocky Point Cycle, Motobins UK, and Siebenrock. A few came from Bob's BMW, but I've had a little difficulty with them. I still like them, though. There is also a BMW dealer in town, and they've been a decent source of parts also. The only work I couldn't do was the machining for the engine rebuild, but I found a great machinist and developed a relationship with him and now I bring him all my projects. The most important source of knowledge was the Yahoo group called slash 5 united (/5 united). Amazing knowledge base, all technical, no assholes, no trolls. Probably the only real difference I would have made the next time around is to have the frame powder coated instead of painted. I know that's a holy argument, and I thought about it a great deal before having it done. In retrospect, I would have done powder coating hands down. Anyway, one of the reasons I bought the BMW is because there are so many parts available and the amazing knowledge and character of the technical support groups. Plus, now that I've gone all the way through the adventure I can help others. I'll admit that when I bought the bike it would help me meet women, but just like my 914 all its done is help me meet middle aged white guys. Sigh.

I've been through a complete disassembly / reassembly with this bike. Rebuilt motor, 5-speed gearbox, electronic ignition, HD springs, rebuilt saddle, repainted, rebuilt gauge cluster, etc. It's weird to think that for a year it existed, then it didn't exist as a whole, and then it did. Very existential. The bike has 227,000 miles on it. This bike is easily the best, most dependable vehicle I've ever owned. It's exactly the same month and year as my 914. August 1971. wow.. awesome job! did you do most of the work yourself? nice nice job do you have any recommendations for part sources? I need to start tearing mine down in the next few weeks brant Very nice job! I've had really good luck with Bob's BMW. |

Spankmeister, Do you ever go to the OVM Vintage Motorcycle show in Corvallis? It's in May... they ride on Saturday and show on Sunday. It's a pretty good show. Lots of beautiful iron.

Thought you guys might enjoy taking a look at a pair of R100's I finished this week. I twin plugged and ported them for a mixed use bike (it will see some track time). Once finished they got a black heat dispersant coating. A very nice pair of heads for what I'm sure will be a fun bike!

QUOTE Is the black dispersant something anyone can use? What is it? Rick I'd like to tell you what the coating is, but that is proprietary info. I have used it on other aircooled heads as well, T4 included. It is great stuff! Aside from great looks (not a big deal on a hidden T4 head) it helps shed heat big time. I considered doing it on our SCCA race 901 tranny housings, but heat hasn't been an issue for us. In '09 I prepped a pair of R75 heads for a R60 bike that a guy used in the Iron Butt Rally. They got a complete bullet proofing, new seats guides, valves, springs, twin plugs, minor port work and they also got the coating. After 10,000 miles in 12 days, nearlly all of which was done at full throttle the heads came back to me. I would like to say that they were in great shape, but they were not! The engine was tuned by ear with no EGT's monitored, or CHT's! Only oil temp. The rider (Joel Rappaport) said the engine ran strong the whole time and oil temps were great. He thought that he got some crappy gas at various tages around the U.S. but was thrilled to have completed the rally in the top 50. (He got a lot of kudos from the oprganizers and fellow riders for accomplishing that feat on a vintage bike.) He was shocked when I told him the heads were basically used up. I believe that if not for the coating the heads would have melted! He hammered exhaust seats that are good for 1600* with unleaded gas! Judging from the chamber color the engine was seriously lean! I was proud that no seats fell out and they got him through the event considereing what they had been through. Joel said he would run 14 hours a day at full throttle! I like the coating and it is not expensive. |

I am planning on replacing all of my charging and ignition system soon. Have any of you used the Omega 450 system and or the Enduraspark system ( ignition or charging ) ? I'm looking for any feedback, and also to make sure they are compatible ( one won't F with the other ) I'm REALLY trying to get this thing done by spring (IMG:style_emoticons/default/unsure.gif) Enough so I am going to drop about a grand taking a one on one metal shaping class with a guru and make my seat. This is one of those guys that can make something like my seat from aluminum and it can be polished when done it is so smooth. Definitely will be trying my abilities on this one. I have made the thing 3 times now and just can't get it to where I want it (IMG:style_emoticons/default/sad.gif)

QUOTE Rick I'd like to tell you what the coating is, but that is proprietary info. Unless I've mis-interpreted some of the comments and emoticons after that reply to Ricks inquiry some folks thought I was being a ass about the coating material. What I should have said is that the people who do it for me won't tell me what it is. When I ask they say it is proprietary. It feels like Teflon, but I don't know for sure. I know they use it on a but load of parts for NASCAR and Indy cars. If i knew I would say. It's not like I came up with it and I'm worried that someone is going to steal my secret!LOL (IMG:style_emoticons/default/beer.gif) |
