Forks

[Stevo]

My forks on my CBR seem to not be dead true. Ordered and fitted a new front fender and it does not sit dead true.
Can anybody please tell me the simplest way (cos it is not obvious and not too far out) to determine where it is not true?

Cheers

How do you mean?
You can make sure the triples are parallel to one another by loosening the bottom triple clamp bolts slightly and moving the forks till they're right by eye. You can do this by twisting the front wheel when the bars are at full lock.

Some people don't realise that even thought the fork caps are the same height at the handlebars, it doesn't mean they're the same length or that the front axle isn't crokked as a result. This can make the forks bind slightly as they go up and down. The Firestorm's caps were levela the top, but with the forks fully extended, one leg was about one to two millimetres lower at the axle.
A trick to ensure the forks are the same height is to take the front wheel off, pull the forks down so they're both fully extended, sit the axle loosely in the forks, loosen one side of the triples till it's just holding the fork leg gently, then using a soft-faced hammer, tap that fork leg up / down till the axle rotates without binding in the axle holes.

Ok
Well I asked a local mechanic this arvo (who races) and he suggested that perhaps the fork is twisted slightly in the triple clamp so I will have a look tomorrow.


Actually now I think about it that does not make sense as the bottom of the fork cannot twist if the top part is twisted in the triple as the axle is holding it straight?? :spudwhat: with the axle and wheel removed (ie the part the the guard is mounted on!) the bottom of the fork can twist easily. Hmmmm. I'll do some more investigation.

The next question will come soon........

also make sure forks are both the same height in the clamps as a slight diff will put the bolts out of alignment.

get a tape measure.....and measure fron the bottom of the bottom triple clamp to the bottom of the fork.....do both sides and compare!!!!
