View Full Version : 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...

HTH
Sob! :cry: Just looked at my manual and can't get my head round it.

Bugger, I'm going to have to take the clutch out... but I don't have a removal tool. On top of that I have used the last of my oil on the change. Will have to wait now, god dam it.

You have greased the pivot on the footrest I take it?That's a common source of selection problems.

Yes I covered it in WD40 just in case... seems to move freely.
Have you checked the chain?
Chain? Whats that got to do with it?
Anyone yanked the clutch out that could give me advice, like do I really need that special tool?
Good job its raining else god know what state I would have got it in now.
Dan,
Check the chain tension and condition, because this affects the forces running through the gearbox output shaft it makes a difference to how slick changes feel or work. Also spraying WD40 on the linkage is no substitue for removing, cleaning and greasing the part where it moves on the footpeg assembly. Again This affects the input to the selector mechanism. (My Kwak suffers this and I've tried both methods, night and day's worth of difference)
Both these are easy checks with no specialist tools required so worth a shot.

The chain is in a bit of a state from the winter riding, though its not over tight or anything like that. I'll take the linkage off if it stops raining...
Cheers.

Don't' worry about a bit of cack on the links as long as when you spin the back wheel the chain tightness is correct at all points and there are no tight links. I'm sure the scottoiler means it's got lube on it.

Just mash it in man 8) :? :wink:
Check the lifter as well.

Did this on Sunday, as it was a nice dry day...
Fully oiled the clutch cable while I was there too.
Now I got all the assembly off, but couldn't get the foot peg out from the leaver. So I just sprayed WD40 into it and turned it round a few times, then repeated until it was nice and loose. I also greased all the bearings for the linkage arm thing... Took the bike out for a test ride and all seems fine now, but I would like some advice on how to remove the foot peg from the clutch leaver. I was pulling it until I went red and just couldn't free them from each other.

I had the same battle this weekend. Mr Haynes says just slide it off...! Mine was well seized and I spent an hour with WD40, spray grease and still couldn't seperate the gear lever from the footrest- it must be love! I thought there was an aligning mark on the lever (a V in the washer)- not sure if this is the case, as there is no corresponding mark on the peg.
My problems stemmed from the footpeg being a little loose (Probably happened when I dropped the bike-at least I didn't lose the lever!)- so when I moved the gear lever, the peg moved too- put it all back on again and the gearchanges worked a treat- before this it was a struggle to get from 2nd to 3rd, then to get back down from 2nd to 1st after I'd eventually got her into 3rd, even when stopped and forget changing down more than 1 gear with the clutch disengaged.
Sweet relief- no need for a new clutch after all. Another £110 I don't have to spend. :D
Hopefully someone will give us a clue on how to pull them apart.
