Firstly, I dare not call this a renovation as the majority of the work I've seen on here on here exceeds, by a significant magnitude, what was essentially a clean up and road prep.
It seems an awful long time since I made the trip up to Patna in Scotland to pick up this BMW K100. It met the relevant criteria of being original, low mileage and cheap
Despite having ridden and owned a variety of motorcycles, I knew very little about BMW's other than their reliability and ability to absorb huge mileages. I was seeking an RS100 but unfortunately they fell well outside my budget. My original plan was to build a café racer but following advice that the naked k100 isn't all that common, I decided to keep it in its original form.
The bike was tired but running and had only recently been taken of the road, there was a comprehensive history file and the previous owner had had it in excess of 10 years. A thorough investigation of the bike revealed that the rear shock and forks were leaking and the silencer was cracked at the junction with the downpipes.
I was also surprised to find that the injector bodies had corroded so badly that one snapped on removal. The TB's looked tatty and a chance find of some almost brand new K1100 one's had me going down that route.
Aside from the TB conversion and uprated injectors, I've renewed all the filters, oils, spline lube, cleaned connectors, new fork seals and dust covers (horrendously priced genuine BMW items
), a very nice rear shock (not sure which model its off) and a chance find Motad silencer that interestingly has the Motad name and regulation numbers stamped upside down. I also changed the LCD clock from a damaged donor instrument binnacle because the original had bled.
I replaced the tatty radiator screen with a piece of perforated aluminium and I'll be doing the same with the screen on the soon to be fitted belly-pan. I also managed to get hold of a genuine fly-screen that will be fitted as soon as the mounting plates arrive. Till then this is how it looks now.
Along the way I've managed to acquire a surprising amount of spares (only because they were cheap or free), in fact I could probably build another bike and to that end the previously mentioned café racer looks like its on the cards. I've just seen Heikkil's post and note that he is using some of the parts from BSK I have earmarked as forthcoming birthday/Christmas presents. I appreciate that café racers are probably becoming a little clichéd but they are my era and the fact that K spares are currently plentiful, there is a huge amount of knowledge out there to improve on the original concept and I have most of the parts would make it an obvious choice
Thanks to all on here who helped and advised with the bits I found tricky.
