Q Why does chang­ing gear fill me with fear?

Motorcycle News (UK) - - Garage -

My 107,000-mile, 1995 BMW R1100R has de­vel­oped a strange gear­box fault. Be­cause of the weather I have not used the bike for around five weeks and when I went out on it to­day it took sev­eral at­tempts to go from sec­ond to third, then fifth wouldn’t hook up from fourth. Chang­ing down was still good. It was very hit and miss over a 70-mile run, but got slightly bet­ter to­wards the end. Ken Jaques, Hull

AAn­swered by Ian Tay­lor, Mo­tor­work­suk They did have a few prob­lems with th­ese early (pre-’97) gear­boxes, mainly worn se­lec­tor forks. But that is­sue would grad­u­ally get worse, rather than one day fine and the next day un­us­able.

Be­cause this has come on so sud­denly, I’d first check that the gear­lever is op­er­at­ing cor­rectly. It has two ny­lon top hat bushes that can swell with age and get tight so the lever doesn’t re­turn to its rest po­si­tion. If that hap­pens you will be try­ing to en­gage the same gear again and again.

If the clutch ad­just­ment is set right, I’d check the con­di­tion of the re­lease mech­a­nism as it sits at the back of the gear­box and catches a lot of road muck.
