If you have checked you valve and
know the could do with a re-grind, it isn't that hard to do, you will need
a grinding tool and some fine grinding paste, which you should be able
to get from any good motorist shop
firstly:
| 1, Smear a small amount of grinding paste onto the edge of the
seat, making sure that you cover all of it. |
|
| 2. Place the valve back into it's guide. |
|
| 3, Wet the rubber end of the grinding tool |
|
| 4, Place it into the valve you are about
to grind. |
|
5, place both hands flat and rub them together, pressing towards the
valve gently, and watch the valve turn about 1/4 turn and back, do this
for about 30 seconds, then pull on the shaft of the tool, and pull the
valve free from the seat, turn the shaft 1/2 a turn then repeat the rubbing
process.
Note 1: you will feel the paste work, when it feels smooth as
you rub, it's time to use more paste.
Note 2: when you want to check your progress, use a rag and clean
both seats. |
|
What should I look for
| Both seats should look very smooth and shine more than any other part.
no little black marks visable. When that is done, it's time to rebuild
the valve. |
