1985 BMW R80

Postby Dougo » December 3rd, 2016, 11:15 am

So it begins.... I was beginning to think that Luke would never get to the point where he had concentration enough to work on the bike, but his improvement over the last few weeks has been good. He started to play video games again, which when he started he couldn't even turn on his computer. he started out not being able to tune his guitar, and last week he started playing and singing again.

I told him we could start working on the bike today, and his answer was quite positive, and then he left with his brother to go do something instead of work on the bike. But I don't care. He can do it. So even if he isn't here today when I start, he will walk in at some point and help, and that's ok by me.

Now to the bike:

I know that the engine needs a few things, So I'm going to start with a complete disassembly, which will show me that I need more tools of course, and do the appropriate measurements to gauge the wear and see where I am at in regards to replacing bearings and any other things I may need. This one will be different from the other two I've worked on. Of course they were k bikes, and this one is an R, but more than that, I've never gotten in this deep to one of these engines. I've rebuilt a Yamaha 650 twin, done a lot of work on VW bug engines, done a valve job on a VW rabbit I had and been lucky enough for all of them to start and run well after the work. But I've never done the detailed measurement work that this is going to require, so it should be fun. I have a few measurement tools, but more than likely I will be crying for help with that, andI know you guys are always there for me with any help you can offer.

But first, it's not raining all day, so I'm going to go for a ride....

Get a torque wrench that you trust. It's really easy to strip the threads in that engine case. The cylinder studs are usually the biggest problem.

Looking forward to watching it come together.

Glad to hear Luke is showing signs of improvement!

Anxiety is keeping Luke from working on the bike with me. It is his bike, so I'm going to be patient and wait. Not what I want to do. He is slowly improving, but it has been 3 steps forward, two steps back. The doctor has told us that his anxiety is normal, but also temporary. That's a good thing. (Big sigh...)

Here's to hoping he gets better.

I've still got a set of carbs that I'll loan you when you progress far enough to need them. They're in good shape. I think I have the stuff to make one more set of spark plug wires for that bike. Same story there. When you're ready to test spark let me know and I'll bring them around.

If you email Murph and schedule an appointment, he'll probably let you snoop around the shop and look over his parts. I think he's got everything you need although I haven't seen a rear swingarm or driveshaft around lately. Doesn't mean they aren't there, though.
