Mine did that often, but it's always my fault. I don't know how you shift, but I find that it happens when I downshift, say from 5th to 4th, but don't allow the shifter to come all the way up (my foot remains resting on the shifter). .
Mine did that often, but it's always my fault. I don't know how you shift, but I find that it happens when I downshift, say from 5th to 4th, but don't allow the shifter to come all the way up (my foot remains resting on the shifter). I try to go to 3rd, but it's as you say, with no resistance. I think I'm just not allowing the shifter to ratchet into place on the next gear.
It's even happened when sitting still, shifting into first from neutral, then trying to go back into neutral. Sometimes I'll have to release the clutch a little to move things around down there to get it back into neutral.
In either case, I think it's my fault for not deliberately allowing the bike to shift. It rarely happens now, but seems more likely if I'm wearing my clumsy boots.
just a bit of an update, and because I have been spurred into action by hotboppincat's post.
read thru the Haynes manual and it lists a number of causes.
one includes going to a heavier oil than recommended, and I have switched to 20w-50, plus another cause could be the clutch not releasing due to much play or slop in the clutch lever. it is only meant to be 1-2mm as forchetto showed with some illustrations in the other post
I dont intend to go to a slightly thinner oil, especially as down under we are getting into summer, but I checked my clutch lever free play and it was way over spec, about 5mm
therefore adjusted it to 2mm. felt funny at first and took a while to get used to, but as I had to go to the city and after a hundred kilometers of stop and go traffic didn't have a problem with it except maybe once, and then I am not sure if my boot was entirely off the lever
problem now seems solved
