If you haven't done so already, scroll down in this document for two images of the relay box to get some understanding of what you're seeing. The image on the left has been rotated to fit the page but all the components and their orientation are the same as the image on the right.

That is for the early 2V models, to much different from the 4V electrics....becoming more confusing than helpful.

Inge which relays are wrong? Here is a better picture of the relay box as it is

Of the six micro relays (arranged in two rows) the ABS warning light (blue housing) should be at rear LHS.
Rest of the relays should be the yellow or black which have the same function.

But you never know on a bike like this what mods is done for the rearrange of this and that.

There seems to be a large hole where the temp sensor relay is supposed to be....  that might explain why the fan doesn't come on

The temp management relay is a 2V thing......the Motronic unit takes care of this on your bike.
Fan relay is in the front center of the six micro relays, and as said get its signal from the Motronic.

Put on new Shinko 230 Tour Master Tires and went up Big Tujunga Canyon.  The Shinkos are replacing Michelin Pilot Activs.

Yee-Haw'd about 140 miles...  Ran the Slimey Crud Run from Pine Bluff to Leland, WI, then took the scenic route home, over the Merrimack Free Ferry, thru Lodi and back home.  Ran down a couple of WI Rustic Roads as well.

I put my wife on the back of my K75S.

I'm thinking it'll be fine for a short restaurant ride or a Sunday ride. I don't think I have the "giddy up" I'd feel comfortable with compared to my previous R1200RT. I miss that bike. It was far more capable than my Ultra Classic (Motorized Sofa) in the twisties and had way more passing power.

I'm working on getting her blessing for another RT. Of course I may have to sell the Miata.

Fact is it really is harder moving down than up in bike size. Not knocking the brick, but the Queen Bee "feels" safer. This just might be my ticket. So which bike? A RT 1150 or a 1200? I'm not too keen on a new anything.

I did put some Progrip Rally's on it the night before. The original ones were hard as Chinese Arithmetic. I think I lost weight putting them on.

Wish me luck.

Good luck.

Sell the Miata and fill the same space with motorcycles.

Don't rule out the R1100RT - I had one for quite a while. If you can find a clean, low-mile example it will last a long time. If you want to explore outside the BMW marque take a look at the Moto Guzzi Norge and the Yamaha FJR.

After my ride in the hills the brick needed a bit of a tune up, it was backfiring a lot more than normal on over run. I balanced the throttle bodies which were slightly out, checked the TPS it was fine. Broke out the Gunson exhaust gas analyser and adjusted the mixture out a bit. I could only go for a quick test time will tell. I also found a slight exhaust leak which could be a contributor.

Went for a  bit of a ride to  check out the backfiring. I got a bit of popping occasionally down hill on over run. The exhaust leak is the bane of my life as so far I have refused to buy the OEM mica gasket for $50.00 Au. I have tried various putty's aluminium and copper sleeves and I know what I need to fix it. I need aluminium or copper sheet .75mm thick, I can get .5 mm and 1 mm. At the moment it is a very small leak so I might just live with it until I either find some .75 or I crack and buy the OEM mica gasket.

Don't give up too easily!
I cut up a drink can and wrap "a few times" with a little exhaust sealer.
The mica rip off is for "typical"bmw owners.We're way past that,arn't we?
Also,glass fibre woven cloth with exaust sealer will work.I build cedar strip kayaks so have heaps.

I saw an excellent solution to the gasket problem done by Bocutter Ed.  He used a section from a brass sink drain reducer as the source material and through clever drilling and cutting, created an expanding gasket that slipped over the header pipe.  There were no seams to seal.  It was posted to this forum but I had no success in finding the reference.  Maybe Ed will pipe in.

Had an email conversation with Ed about his really cool solution, however the plumbing part required is not used or available in OZ. I tried a variation with what was available but couldn't get it to work, the material available was too thick.

Put the Mystic Red base coat on my fairing parts Yesterday.  They go off to the painter for the clear coat on Friday.  Gonna do some wiring for my heated jacket now while the fairing is off.

Would post some photos, but I can't resize them.

  This is the type of heated gear controller that I mount permanently on my bikes to control my heated gear. Can be mounted anywhere in a project box and leads extended to mount knob on the dashboard or handlebars.  BMW style access plug is then mounted in a convenient  location. Many different styles and variations available. Very inexpensive.  No affiliation with sellers.  Do Ebay search for:   Universal DC10-60V PWM HHO RC Motor Speed Regulator Controller Switch 20A New

I call it a collet gasket, because it works kinda like a collet chuck.

rbm, I did a search for 'collet gasket' and ... nothing. Possibly I never posted the process to make one.

MW074, great minds think alike.  Exactly what I did with mine.  Board was $4 on eBay.  put it in a small project box velcro'd in the left side glove box in the fairing.  Put an illuminated switch on the fairing and a plug in the knee pad.  Trouble was I got some sh!t wire and now I need to rewire everything along with my LED running lights and fan override.

I got rusty nuts. No, on the bike, but not as bad. Got no real experience with how to resolve that issue.

All depends how bad they are,mine were so rusted that I don't think I could have removed them in any reasonable space of time if I hadn't used an oxy acetylene torch.Even with using the welding torch two were very difficult and I thought I might end up drilling/tapping.Plenty of time/patience,vibration and penetrating fluid often frees most rusted nuts

I've seen some vids on heating the nut with a BIC lighter until candle wax or bee's wax will melt and wick into the threads.  Works in the videos but I have not tried it myself.
