I was very happy to see the innards of the tank in pristine condition as well as the pump, damper and the float resistor. Calibrated the bastard by the way as I NEVER had my tank full according to the gauge. Hopefully when it all goes together I will have a better idea how much fuel really there is in the tank. Things I defo hate are the stock seat, the heat and the windscreen.
The float position or the sensor can be adjusted so you'll have a more accurate fuel warning. Read all about it here. Steps can be taken to reduce heat felt when riding. One way to deal with it is discussed here.

soooooo.... I'm in my second season bricking and it has been relatively good so far, however I started reading this forum again when I could not stand the smell of petrol in my garage and it sort of opened a box full of Pandoras :D  :musicboohoo:

I have actually to my disbelief located a tiny hair crack in the right lower corner near to the seat. So small the fuel was evaporating as it seeped out - hence the smell and no 'leak' as such. As I weld aluminum I may give it a shot with a TIG torch but when I think of purging this tank with gas I may just sandblast a couple of centimeters in the close vicinity and dab it with a drop of two part polyester resin which to my knowledge is fuel resistant.
My reluctancy to weld the thing is caused mainly by the fact the aluminium really moves when you apply heat and do not want to have some other cracks to develop maybe along the lines of the present one. IF the problem persists I will give it a good sandblasting and weld the whole seam up.

While I was at it I finally decided to have my throttle sync check /waaaay off/, and the valves checked - now sit for that.
NEVER took anything for granted and it is a good way to go. According to one YT BMW mechanic, he has never seen valves go tight on 1100 - well mister you might have not seen enough.
Three of my exhaust valves are loose in the 0.32 region /0.35 feeler is NO-GO, 0.3 goes in tight/ but my INLET /!/ from the timing chain side is TIGHT - 0.12 I reckon from approximated measurement. ALL of other valves are ideal spec.
The bike has 70000km and I think someone f..ed up this one on check long time ago. My wild guess.
Will have to pull the cams and BOTH of them as I plan to swap the buckets hopefully - the exhaust side is loose - the intake is tight: it may give me an opportunity to have it swapped upon measurement.
The BMW book of wisdom says you can only swap the buckets on the initial 1000km inspection. From then they need to be replaced with new. Can someone confirm on that???
During the winter I am planning to put the whole valve train in the production spec - now I do not want to have the bike standing.

Also my combination pump leaks oil - it was intense when I started riding /the bike stood for YEARS/ and stopped leaking /same as clutch/ but it is wetting the bottom of the bike on the constant basis which makes me unhappy. So it is another thing to do.

These and new tires bring the brick closer to my heart /and wallet :D/ but I like the bike. Things I defo hate are the stock seat, the heat and the windscreen. To be worked on in the future.

The Motobrick Workshop / Re: Lean when leaning

When it was leaning left a large crack in the crankcase breather tube opened up more. Which in itself isnít a huge amount of air. But combine it with the way the bike was tuned to compensate for the damaged tube in the first place it made quite a difference.

Thanks Laitch!

Odo reads 55753

With regard to my experience I've been riding for less than 2 months. I have taken the basic rider course
I'm definitely not excited for  that first service trip haha

I am low on brake fluid and already bought the DOT4 BMW. Is it going to be ok to add the fluid so long the reservoir  isn't gunky.

I'm using the motogadget m.unit as well as the Motoscope Mini, Motosign Mini, and m-Button.  My understanding is that I can basically eliminate all the relays except the starter relay.  I haven't dug into the electrical plan too much yet though so I may be wrong here.  I'm considering just redoing most of the wiring though to clean it up.  As I mentioned, still need to dig into the details a bit.  But I think I have some of the basics down at least.  Not entirely clear on the speedo, some of the indicator lights, and the ignition stuff among other things but that is all on the list of things to probe into.

Separate question as I dig into the frame modification... I'm thinking about just getting this eBay seat: https://www.ebay.com/itm/26-inches-BMW-K75-K100-K1100-80s-90s-solo-cafe-racer-Brat-seat-CODE-S3191/112610955247?hash=item1a3822cfef:g:ru0AAOSwR29ZKnVd

Seems like a reasonable value and it's basically exactly the look I was looking for.  Also, it should bolt right up after the requisite frame modifications which is nice.  Any other suppliers out there that would offer something similar?  I also had the thought of bring the stock seat to a local upholsterer but I doubt it would be as affordable.

I normally use my wife's hairspray to install the grips. It initially acts as a lubricant and then as an adhesive as it dries. It is also easy to remove them down the track without having to cope with glue residue.
Regards Martin.

But I need a tail light first.  Any recommendations on an LED tail/brake/turn signal light?
Figure it's tough to go wrong for $10.
Do you understand that you'll need to modify the flasher relay to use the LED turn signals and do other modifications to use an LED brake/tail light successfully?

. . . And have them bleed the brakes and ensure everything is up to snuff..I haven't checked the brake fluid reservoir prior to typing this but right now I am too lazy to get up heh..
-Recently the grips on the left side just slipped off and want to take care of this immediately so I'm going to buy some this week and install them onto the bike..any tips or advice on that would be greatly appreciated.
- I really would like a new instrument cluster and new headlight(not a refurb'd stock one).
Thanks for all the photos. Well done! How many miles on the odometer? I couldn't read it. You write that it is your first bike. How much motorcycle riding experience do you have? Have you taken a basic rider's course?

Here's some of my observations.
  • I am confident that once you get your first bill from a dealer who brings everything up to snuff, your laziness will miraculously disappear. :giggles
  • Grips? Pro Grip 699 is a popular model, closed or open ends available.
  • Installing aftermarket instruments can get complicated. Hold off until you have the bike thoroughly roadworthy. That will include inspection of the transmission input splines and the final drive input splines.
  • There's a date code on the tires. How old are they?
  • Get a four-dollar bulb siphon from the hardware store, and a screwdriver. Remove the fuel cap assembly gently, siphon the fuel into a fuel container, take some photos of what you see in there then post them here. If what you see is a shiny tank with no debris in it, turn the cap 180ļ, install it with its hinge rearward then move on. Take a nap!
  • Be patient.
Almost everything that has ever happened to a K-bike has been discussed and treated here multiple times. Go to the Repair Guidance section for information. Learn to search the site effectively. Download a manual from here. Download a riders manual. Here's another good source for information, as is the K100-forum.

Good luck! This could be a great ride.
