Problems with changing down multiple gears
 

I suspect its the oil breaking down causing odd things but this week the bike has started no changing down a gear. The exact symptom is as follows -

Occasionally when changing down a gear with the clutch fully pulled in I can move to the next gear down but if I try to drop another without releasing the clutch the gear select leaver moves but no selection occurs. So If I try to go from 6th to 4th in two selects it fails.
If I release the clutch between these selections then it all works correctly, so if I go 6th to 5th then to 4th i have no problems and it only seems to happen in high gears.

Now the bike is over due a oil change (to be done this weekend) and I have been riding her in some really crappy weather. Hopefully the change will fix it, but I am worried the select is going. If it is at fault how much of a big job is this to fix?

Hmm, do you normally blip the throttle as you change down?


.

On single changes I think yes... but this is when I've slowed down alot, say via breaks and then had to drop down a few gears to match my new speed. Or if I trying to scrub off alot of speed but not with the brakes, and drop 2 gears on one go.

I think...

Well my experience of sequential gearboxes is that they don't like being asked to change down at low speed/revs, particularly if you're block changing. Give it a good blip for each cog you want to swap and see if that helps — or just ride better and be in the right gear in the first place :lol: :wink: .

That is true, but I've not ever noticed it before.

Mine gets very rough at gear changing when the oil needs doing,and if the chain is out of adjustment.

OK, its still acting all odd. Changed the oil, adjusted/greased the clutch push-rod, and clutch cable.

I know its still buggered as when I change into first it don't lock in firmly, its just, well, soft... its hard to describe.

Bent gear selector fork not properly engaging each gear??? Dunno?

Its more ideas then I had... just got to figure out how to pull it apart...

Dunno.
