O.K. kids, here's the deal! On some Derbi
Engines you wake up one morning and go to ride your bike and
only have 3 gears instead of six! This does not happen often,
we have only heard of 3 cases, but 3 is too many! If you are
a street rider this means you go real slow until you fix it.
If you are racing it means YOU LOSE! Either way, it is not a
happening thing! So let's fix it, it's easy!
This is the Shift Shaft. It is under
the right side cover. To see how to remove the cover refer to
the tech tips for clutch replacement. (This is also a good time
to replace the clutch)
......it will soon look like this! In other words, broken! The result is only three gears. We have new shift shafts that we have reinforced. Replace it! This is not a hard or complicated job, it just pulls out and you just push the other one in. Go for it, before you too have a 3 speed!
