On my way to project VND to collect my panniers and the bike's broken down, won't change gear and is currently stuck in second. AA are on their way and will take me the rest of the way, looking for suggestions on what to check when I can poke the bike properly.

Clutch works, pull in and the back wheel spins fine
Gear shift moves up and down same amount as normal, just doesn't engage a gear.
Tried rocking it back and forth and still won't engage a gear.

Everything else was fine, came off the motorway after 100 miles and approaching the island it started being very reluctant to change gear, got worse over the next half mile so pulled into a lay-by and can't get a gear change.

Not great timing as I'm on a week's trip around the country visiting friends.



Ideas?
 
When my 1200 did that I kept pushing it backwards and forwards and eventually it freed up. It took a while but worth keeping trying until the AA arrives.
 
As someone has already stated it is normally the linkage sticking due to a build up of dirt, salt and other crap. Try and slacken it all off or remove if poss and grease it all up or try squirting some WD40 in there.
 
he,s stated in his post that the gearshift moves up/down as normal, its not sticking
 
try pushing the gear lever towards the bike whilst pressing it at the same time.
mine did the same thing - crap in the linkage was the answer :)
The grease was rock solid once I got it apart to clean and regrease.....
 
None of the above has helped but thanks. Linkageexternally looks clean and its moving the rod that goes through into the gearbox so this starts to look expensive. Will have a better look when I eventually get to Vern's. AA sent a transit and a guy who poked it for 30 seconds and said, you need a recovery truck *headdesk*
 
IF the outside Gubbins is free and operational it is probably the roll pin as it connects to the internal gear selection bits

I had one go a couple of years ago took ages for the part to come thru and it was just a roll pin But I hadn;t enough to know how many rolls or length as it was mulched
 
Although the gearlever seems ok it can still give gear changing problems if the mount is nearly seized. It doesn't return quickly enough or positively enough to index the next gear.

Remove the small circlip holding the gear linkage rod to the lever, knock the ball out of the socket and see if the foot lever falls down without any hesitation.

It's usually the lever seized on it's bush. You can't squirt WD40 in and free it up as it's the actual bush that runs through the gearlever itself, so even with the gearlever removed you still need to push the bush from out of the lever and grease well.

As a temporary measure loosen off the gearlever mounting bolt a couple of turns, so by passing the bush if you see what i mean.
 
Thanks Neil, I'll have a better look when the AA eventually get me to vern's. The linkage seems fine though. The lever returns up or down from where it's pushed on it's own and seems to be moving the rod going through the casing. Will report back when I've had a closer look.
 
Well, when i drained the oil i knew there was a bit more going on inside than just selector problems -the oil was liquid silver.
The input shaft bearing input end had collapsed and the bearing cavity in the case is damaged .
The sprung selector on the selector fork was jammed, the selector drum has some nice widened grooves from the selector forks, and the teeth on some of the gears look like they've lost some hardening.

Apart from that it's all Ok :D

Any idea what might have caused it. I'm not ham footed when I change gear and the fluids have been changed at regular intervals. Seems like something bad has happened in there.

No idea. But bearings aren't for life, they do wear out.
