Because spoked wheels much better

I wish I 'spoke' Russian...

Nice

Anyway I'm hope it useful.  At least it have english subtitles.
Next step %) I wish)

That's a nicely done, professional-looking video clip. It was interesting to see a 19" wheel going onto the front end, and as an aside, an 18" tubeless, spoked wheel (but for 110/80ZR18 tyre) can be obtained from 1990's era R1100R and Police R1100RT from California, if you don't wish to jump kerbs and span large potholes with a GS proportionate 19" wheel and tyre. A sweet, custom look indeed.

Let's hope that behind the scenes some effort was made to measure and shim the replacement ring gear with the original pinion gear otherwise we'll have a well and truly fragged final drive on about the second or third short ride.

Thanks for that.

I didn't understand last comment. What do you mean talking about original pinion gear? I left gears from K1100LT , I changed only finel drive's cover....
Explain, please, I have not tested bike yet and will not do it soon)

My apologies, I must have been mistaken. I thought I saw a different ring gear being swapped into the final drive to mate up with the pinion gear. It must have been a language barrier.   I'll have another (closer) look at the video.

Nice modification.

Cheers.

About 18inch wheel - yes, for race bike it's better to use 18'', but it's hard to find such used wheel. Anyway it's easy to change it anytime. Now we are going to drop front end to recover handling. By the way 19'' looks pretty cool! 


Fuel tank from the inside

Looking at the video, Konstantin removed both covers with their respective ring gears intact.  He then removed the ring gear / bearing assembly from the old K1100 cover and swapped it into the R1100GS cover.  Shimming of the pinion may not be necessary if the bearing holes on both covers are precisely the same relative to the K1100's final drive case.  It's probably not a bad idea to check the clearance on the pinion gear using the process described on page 33.15 in the BMW K1100 service manual, just to have peace of mind.

Wow, nice!! Certainly a very rare view of how this part of the motorcycle is designed and constructed. Very educational. Thank you for posting Konstantin.

Great photos!

That is great to see the tank from the inside. some really good work you are doing. Thank you for sharing and posting. Would you take a photo of the filler area from directly into it as I want to see how the return line finishes near the filler and how the breather is in the same area.
I am looking at combining 2 tanks to make a bigger tank for the K75 GS I am building.
Thanks in advance.

Have in mind that this "breather box" have been changed at least two times
during the lifetime of our old beauties, early models did have it behind the
filler cap.
The one in the pictures is the early 11LT....but I believe that the breather was unchanged on the later one.

very nice. very nice indeed.

Those wheels looks fantastic! I want.

The pics of the tank are great too.

Thank you very much. That is just what I needed to know.

fantastic video mate, and the bike looks sensational. Any updates?

I must confess, I watched this about 4 or 5 times trying to work out what was happening....then I realised there was a subtitle option...

I will certainly be doing this to my bike. When the current front tyre wears out ill try and source the 19'' rim with rotors.

Not so much. But something.

It's doable, Floyd, but you will need the Marzocchi forks, 305mm brake discs, four piston callipers and 20mm m/c from a K11 to fit a 19" front wheel to your earlier model. The calliper mount spacing holes and the offset are quite different from 8V to 16V models. But out in the Red Centre on a dusty track a 19" spokie with knobblies would lead the way for sure!

Cheers twb. Already got the k11 front end on my k100 as well as the throttle bodies

Excellent. Then all you'll need to work out is the 20mm axle diametre and what to do with the speedo drive on the left hand side if using an R1100/R1150GS 19" wheel. Dunno if an R1200GS wheel is what Konstantin is using. They don't use a drive gear there.

This motogadget is a very cool little unit. Very expensive, but very cool too.

Sooooo....when using this little magic box do you still need to use the fuel injection relay and the fan relay?
