A few weeks ago I bought a 1984 K100 with 32000 original km. I like this year as it is pre-ABS and has rear disk brakes. It had been stored for 2 years. I took it out for a couple of rides and noticed a some drops of oil coming from the rear weep hole. On the 3rd time out the drip turned into a puddle of fresh engine oil under the the center kick stand. I know now that I should stop riding and replace the rear main seal and o-ring before the clutch gets soaked in oil.
I will be converting the bike to a scrambler, so will be looking to this forum for some help and advice along the way. I have started by ordering all of the parts for the rear main seal job and will be checking everything along the way, splines, boots, bearings etc. It coughed up a bit of smoke on startup, but stooped after it warmed up for a few minutes, hope this is normal?
It looks to have been well maintained by a BMW dealership, lots of invoices came with it, almost $6,000 CDN when I added up the total. I have always maintained my bikes without the help of a mechanic so will be doing all of the work myself.
I have a small unimat lathe and today made up a clutch centering tool from a scrap of delrin plastic. [ Invalid Attachment ]
Here is a picture of the bike as purchased so you can see where I started on the build. [ Invalid Attachment ]
I will do my best to keep everyone updated om my progress. lots of work to do yet.
