gear problems
 
right. went for a nice quick ride after work today, then on the way back down a dual carrigeway, it wouldnt shift up over third. though hmmmm, lever might be a bit stiff, so i puched the lever down, then back up and it went into 4th, same again fith, sixth. basicly the lever isnt returning back to its position. got home, wacked it in the paddock stand, link arm a bit loose, tightened it up, started it, then wouldnt go above second without having to lightly push the lever down then up.
Is there any known faults like this, or is it what im thinking it is. the return spring in the gearbox. dont know if anyone else has had this problem.
its a pointy 99 unfaired model if that helps.

Lube your gear lever where it pivots on the footrest.Thats the easy fix and worth checking first.Also check chain lubed and adjusted and engine oil level.Then look at the return spring if it still don't work.

took off the gear lever, was slightly stiff, so cleaned it up, lubed it, then wacked it back on, still the same. i done a search and it sounds like the return spring. could have either snapped or dislodged. but this means i'll have to drain the oil and the coolant, split the crankcase and get into it that way.
any one got any advice???

To fix it properly:

Remove the lever from the footrest and remove the fibre bush from inside the lever *very carefully* - the bush isn't available seperately and it's easy to damage - if you look close you can see where the bush is split, gently get behind it and roll it up a little you'll be able to pull it out, if you look inside the lever you'll see where corrosion has built up behind the bush, expanded, and squeezed the lever onto the footrest pivot, causing oit to drag, if you gently scrape away the corrosion smear the area with a little grease so it doesn't corrode so easily and reassemble it should be fine.

as said beore sid squid, i done all this, i even used the gears manually direct using the shaft and it just didnt return after going up to second. so im going to strip the crankcase later and sort it out.

i adjusted the free play out of my clutch cable the other day and was amazed at how smooth the gear change was after that.

Hooo-leeey shhit.
I just cannot believe what a differance cleaning that bushing that the gear shifter pivots on makes.
Seriously. If some one told me they just put a new gear box on the bike, I would believe it.
Honestly.

All I did was take it off, give the whole thing a really good clean, polish up the bits,make sure there is no corrosion at all, lube up the pivot with a bit of engine oil, put it back in, lighten the whole thing slightly with a spray of WD40.
And bingo, new gear box. It just snaps into gear perfectly now.
