Over the last few weeks I have found it is sometimes difficult to select neutral when the gearbox on my '91 R100 GS is warmed up (30+ miles), which is most annoying at traffic lights!
Checked gearbox oil level, which was full (using Morris GL5 spec gear oil). Selection of other gears seems unaffected, so mystified as to cause of problem, particularly as it is intermittent & no unusual noises from box, which has done approx 7k miles.
The bike had had lain idle for 18 years before I acquired her, which may account for the problem, though I did 4500 miles last year without any major problems. Various seals & the head gaskets have required replacement over that time, but par for course with a 21 year old bike. Someone suggested it may be related to part the gearbox being above the oil level for a long period but I am reluctant to engage in a strip-down unless absolutely necessary.
Any ideas anyone?
