Step by step guide
Tools Needed :
2 12mm open ended spanners
1 pair of pliars
32mm socket and wrench for it, you can use either of these tools to
undo the king nut, but constant use of them will lessen the life of the
nut. I advise a crack bar and socket though.
1 new split pin! |

To see of your chain adjusting, place your forefinger and thump on
the lower part of the chain, mid way between the sprockets (use gloves
or a bit of tissue if you don't want to get oil ore greese on your hands.
Mive the chain high as you can, then as low as you can, if there
is more than 5cm, then it's time to think about it's adjustment. |
 |
| 1. Make sure the machine is on a centerstand or paddock stand as the
job is best done with the rear wheel off the ground. Make sure the machine
cannot topple to easily.
2. Using the pliars, streighten and remove the split pin.
3. Loosen, but do nut remove the king nut. |
|
| 4. Using 1 12mm open spanner, loosen the locking nuts on both sides
of the swinging arm |
Left side.
Right hand side
|
5. Check the adjustment marks on both sides make sure the are
the same on both sides and the head of the adjustment bolt is touching
the spindle blocks.
Herer the six marks are clearly marked on the swinging arm.
There is a lighter scribed mark on both of the blocks. Both of
these are mid point between all six in this bike. |

| 6. Using the 12mm open ended spanner, undo the adjustment bolt 180º
(2 quarter turns) firstly on the left hand side.
7. Do exactly the same on right hand side. This keeps the back wheel
in the correct aleignment.
8. Check the chain, if it's still too loose, repeat steps 6 & 7
until you are happy with the tension. |
 |
| 9. Using one of the 12mm open ended spanners, hold the adjustment bolet
still, while using the other 12mm open ended spanner to re-tighten the
lock nut. on the right hand side.
10. Do the same on the left hand side.

(only left hand side shown)
|
| 11. Re check alignment marks again. When this machine had been adjusted
correctly the feint scribe marks on the blocks were both on the 3rd mark
(BOTH from the rear or the machine). |

Right hand side
|
| 12. Re tighten the king nut on the spindle (to the cerect torque if
you can.
13. Replace the split pin. Make sure you do! If you dont, the nut could
lossen and fall off, then your spindle could move and it could cause an
accident. |
|
14. Remove from stand, push the machine forwards a bit and check
the chain.
15. Check back brake works before riding. It should.
Also check the brake light. It might now need adjustment.
