I have cleaned the whole engine, there really isnt much more to clean. I think it is about time to open the wallet and start burning the c-notes. I think I am gonna start out with the enduralast alternator and the omega ignition. I like the double redundancy there. I think that is very important in an adventure bike. I think having 2 coils would be nice too.

The Enduralast is 100% perfect.

A friend of mine will probably do this conversion during the winter, he has some leftovers from his KTM-days.. I’m not sure if he will shorten the Extreme or not. He also got the KTM rim but it is crap so I’m not sure if he will fit the BMW-rim.

I talked to John Rayski yesterday and he seems to be very responsive on his emails. He even hooked me up with a person who put an omega ignition on it.

I dont really have a good bmw wheel, it would be nice to find an aftermarket 21" wheel for something else.

If you have hubs, send them to Woody's Wheel works. He did my wheels .. check my site. Best wheels you can get. Not cheap though.

I would just need to get the rim, I know how to wire wheels. I dont know if there needs to be a minimum mass for a hub on certain size rims, I will have to look in to that.

21 inch front Sun rim, 18 inch rear Sun rim .... Works like a charm.

AliBaba, could you please PM me whether KTM triple clamps fit the BMW frame and how this conversion works if your friend decides to do it. I'm really interested in this modification. My main concern is a different offset and steering angle.

no need to pm. I am also very interested in this. I want to start a list of all candidate forks and try to get the plus and minuses for each.

The steering geometry depends on a lot of variables. If you machine the fork so it gets standard BMW-length you will get the same steering angle but the offset depends on the triple clamp and the fork (how/where the rim is mounted).

I will post info if he does the conversion!

You may find it helpful to look here Welcome to Boxerworks.com

They have a wealth of technical knowhow. also tere are several sources of parts off from it. I have found Motobins to be good. Bt I am extremely lucky, not two miles from me a a BMW guru with a huge workshop and acres of parts.

Forks
I've been thinking how to improve the front end of my bike for some time. First I should mention that I intend to rise the hight of the bike. If I didn't want to change the hight I would probably keep the stock R80/100 GS fork and would experiment with springs and internals and oil.
The forks which I was considering in the past were forks off Honda AT or Suzuki DR800Big. But the only advantage of these forks would be their length. I may be wrong though.
The forks I'm thinking about now are Marzocchi Magnum and WP Extreme. They are adjustable, longer and stiffer compared with BMW fork. The thing I'd like to know is whether these forks would work with KTM triple clamps and BMW frame. Apparently they are both the same diameter. Also, would BMW wheel fit?

Okay, the KTM axel will fit through the front hubb of a R100 GS, but a bushing needs to be machined...it can get complacated. Then, if you are using a KTM tripple-clamp, you will have clearance issues with the brake rotor. I went through all this and in the end had a custom wheel built and built a tripple clamp myelf. It was a lot of work. I would sugest using a complete front end and forget about te BMW wheel. Besides, it's worth a lot of money an helps offset the cost of new stuff if you sell it.
