You don't know how long I have been waiting to say that. I took my 89 R100RT apart last Fall after having it diagnosed by some great folks at a tech day event over near Spokane WA. I had it rebuilt by the fellow in Santa Cruz CA. I also replaced the front brake rotors at the same time. I took it out for a test drive this afternoon and found that the front end was a bit heavy at slow speeds. I didn't push it at all. When I got back in I started pulling and wiggling stuff to see what I had overlooked. Turned out that the front tire had only enough air in it to minimally inflate it. The pressure didn't even register on the gauge on my air compressor hose. Works fine now and it shifts like butta!

it's like getting a brand new bike, isn't it? pretty sweet. congrats on getting it back and good on you for having the patience to get it fixed up. :thumb

Thanks Lee, I was not sure about my ability to do the job in the beginning but being a cheapskate and not wanting to pay someone else to do the work I figured if I took it a little at a time I could do it. I only have one part left over! It's that damn spring I posted a picture of earlier under "name that part" Seems to work fine without it what ever it is. I only had a couple of set backs. One when I stripped the threads on the brake caliper and another when I discovered that the inner coating of the gas tank had failed completely and need to be re done. I'm excited to ride the old girl again. Fair weather predicted for Sunday and Monday.

Doug,

Take pictures and give us a ride report? Lots of folks are trapped by winter and could use a boost like that.

Yours shifts like butta. Mine shifts like toast. :laugh So far it is only lightly toasted and it is on the list. I'm looking forward to the day mine shifts like yours.

I dont know which helped the most but I just put on a new clutch cable, rebuilt the total throwout mechanism as per Mr. Parker, and greased the clutch splines with the appropriate lubricant.

MMMMMMMMMM..........such a difference.............the machine only has 17K on it and is a 1975 R90/6. The grease on the rear splines was hard and came off as clumps.............the clutch spline was dry and a bit shiny................The clutch arm was missing the grease zert and part of the boot that goes over the throwout mechanism........................

NOW.................I have to navigate across some grass and uphill when I come out of my shed....................clutch used to be grabby when slipping it to navigate on the grass and uphill...............NOWWWWWWW................mmmm mmmm smoooooooth engagement and I can actually slip the clutch..............

Shifting had a couple of hangs, clunks and false neutrals between 2nd and 3rd........down shifting was kinda search and feel..................NOW........

Yes it still sounds like you are slamming the breach in a German 88.....probably the same engineering team...........but oh so positive and clean...............

Thanks for all the thoughts on here.............that and HIM guiding my hands........Dennis

My clutch works well and I have a new cable and have lubed the controls. I hope to do a spline lube a a tech day this weekend. However, I don't expect that to cure the tranny problems.

I don't think I can get there without more work. Mine has around 100k on it (who knows for sure with BMW odometers;) ). I will probably do a full tranny rebuild with new bearings and seals. I also want to take advantage of the design upgrads that were made on some of the internal parts. Then I plan to wear out the rebuilt transmission with lots of miles!:dance
