Fix 2
1. Clearly marking the adjustable bar and gear link rod in relation to each other makes life a lot easier and you'll be able to work out which way to adjust a lot quicker (my first mistake!)
2. Before you do anything test 5th gear is accessible and reverse. It may be that you can only get 1st and 2nd through lifting the reverse gear sleeve on the lever.
3. Bear in my that even a 1mm change in either direction on the adjustable rod makes a noticeable difference to the overrall gear selection, as such, only make small increments in each direction, testing the gears as you do each change.
4. If you choose to change the smaller link bar, be very careful with the plastic balljoint holder and the small circlip. They are fragile!
5. Make sure you have plenty of latex gloves...got through about 30 pairs doing this.
