Scrambobber
« on: July 25, 2018, 10:35:51 PM »
Bought this beauty in February. Did many things. Now it looks like this.

I’m not very good at documenting every step as once I get into it it’s hard to stop. However, I thought I would share some random thoughts and things I have learnt so far.
It’s a great bike to work on. Most things have a German logic. All my tools are metric. Good.

Most of the money spent on it has been to get it up to scratch mechanically (e.g. new water/oil pump, fluids, seals, etc). All the little things add up especially when you are buying BMW genuine.

Even though it has ‘only’ done 65,000kms there was still a bit to do get it all ship shape.

Did I feel sad about chopping up a perfectly good fully faired LT? A little bit. However I have only ridden it a couple of times and on each trip I’ve had complements from other motorcyclists on the bike. Would I get that on the stock bike? Maybe (not that I’m seeking attention, but the complements are nice none the less).

BEP3.0 worked perfectly. Would definitely recommend. If you take your time with the wiring it all becomes logical.

Hydroblasted many parts. Great process that removes paint and makes the aluminium look great.

I’m used to a Vespa so it’s quite different to ride. I have some Shinko 705’s and it feels glued to the road, very stable.

I have no experience building bike seats but for my first attempt I’m pretty happy with it. I wanted some bobber style springs to give it a bit of a classic look. Metalwork is just laser cut parts. I didn’t do the leather but the guy who did has done a great job.

What’s next?

After riding a few K’ms I have found an oil leak coming from the alternator drive shaft; so the bike is immobile again until that is fixed.

I still haven’t decided what to do with the back end. I’m going to use this bike to promote my glassware business and thought it would be cool to do a wooden tray that could take boxes of glasses for delivery to customers. Might as well use the great frame BMW created to add some utility rather than the usual chop.

I’ll have to rebuild the front end at some point to match the awesome Wilbers rear shock.

I have some leather left over from the seat build that I’m going to use for grips and a custom tool roll bag.

Once the back is finished I’ll put up some more photo’s.

I suggest Bobbler as the name of this model type.

Love it, looks like the direction I was thinking about taking in my head. What handle bars did you end up using? Are you happy with them?

I used these:

And no I'm not happy with them; too wide and too far forward. I'm more of a cruiser so will be swapping them out for something a bit more laid back and slightly narrower.

Nice looking bike. I am new to bricks and have an 86 k75C with about 80k mikes on it.  Mostly all orig.  My 18 yo son would like to drop the huge muffler in favor for something smaller, up to date visually and allows the sound of the triple to come through.  I see you fabbed a pipe.  Is it baffled? Straight? Did you have to reflash the computer? Can you reflash on something this old? Make any adjustments to the FI?
I have more experience with a mid 90s R, a modern triumph and old carbed Japanese bikes but am uncertain about Ks.  Any advise is appreciated.

I haven't done anything to the computer, no need.

Its been 4 years now, what else did you do to finish the bike? I love the look and would like to see some more pictures of the bike so I can go the same direction with my K100, more pics the better.
