I have this problem on my R100R and and fighting shy of carrying out this fix in case it compromises head gasket sealing as only one rocker is affected and would require two head nuts to be slackened. Did you have any of these problems? On both cylinders I checked and replaced shims and plastic ins...

Exdamine the threads. If they appear complete and the profile is good, refit the stub with stud lock - tighten the nut to the correct torque. If the stud is just a little loose in the thread, it'll be fine. If the thread is so damaged that the thread pulls, it's going to need a thread repair whatev...

Curious...what torque did you finally use on the nuts? Sure sounded like the engine case threads are stripped, but if it took the required torque, then maybe OK. Kurt Torqued to 29 lb ft ( 35-39 Nm). Tightened in stages to final setting. To me it was almost as if the stud was too short, but it did ...

1989 BMW R80RT Checked rocker end play this weekend after valve adjustment still resulted in noisy Tappets. Excessive play found on 2 out of 4 rocker shafts and this was corrected with new plastic inserts and shims. This has resulted in a much quieter top end. My query is as follows. When removing a...

Now that’s got me thinking again!

Being a bit on the short side, I also have difficulty in putting out sidestand whilst sat on the bike. I rarely use it as a consequence, preferring the centre stand, the sidestand seems to leave the bike at a crazy angle! Did see this method of deploying the Sidestand whilst still sat on the bike wi...

Problem solved, thanks for the advice.

As you both said relatively easy to track down the short. Issue caused by badly routed starter cable, with cracked insulation which was touching the inside of the starter engine cover. Slight burn mark on the inside of cover provided the evidence.

One point to mention. On the 'RS and 'RT fairing, there is a known and acknowledged danger that the main positive battery lead can rub against the lower fairing support and short out. Don't know if that's your problem but certainly somewhere to look. Thanks for the advice Rob, I’ll check this out o...

Thanks, for the advice, I’ll give it a look over the weekend and let you know how it goes. Battery is disconnected, didn’t know I could twirl an Allen key so fast once I spotted a wisp of smoke!

1989 BMW R80RT Any advice welcomed, fine with all things mechanical but not so good at chasing electrical gremlins. Much against my better judgement, which is “if it ain’t broke don’t fix it” I removed the Bosch starter motor over the winter break to give it a clean / overhaul. This was mainly a goo...
