Very easy, bout 45min to 1hr if you take your time, not bad considering never done before.
Gear stick now self centers and is easy to operate again
Simple, remove plastic elbow for intake, even easier if you remove the rubber elbow aswell, but i didn't.
Remove battery x2 10mm battery terminals and 13mm nut holding strap down, lift out battery, lift up plastic tray under battery.
Undo 4x 13mm bolts holding tray, then remove 1x 10mm nut at back which holds wiring loom to battery tray, then remove 10 nut holding air filter to battery tray.
Then unclip 4x relay mounts with relays
Then remove battery tray. You now have as much access as you need.
Then undo 17mm nut on gear linkage swivel housing thingy, leave nut on whilst you tap with hammer and suitable drift to push out linkage arm. Note there is nut, washer, then actuating arm with spring , this needs to be slid off whilst you drift out linakge arm.
Then once arm is removed you will see plastic bushes, drift these out easy to drift out back one and then i used screw driver to push down on bush, hook out and remove.
Then with wd40 and sand paper clean out hole. Then apply lots of grease(lm not copper) to keep it all nicely moving. push in new top hat plastic bushes with grease.
Then re assemble. Do not go mad tight with the 17mm nut, just nip it up(it is nylock)
I found that you didn't need to unclip cable from linkage arm, therefore less fiddly.
All bolt were put back in with dab of grease to help aid them come out next time.
Perfect smooth gear stick again.
