Compression Damping
Discussion
Guys,
I need to tighten up my damping at the front end of my CBR600F. Having mainly ridden 125's before, i'm not used to having damping settings at the front end.
Im faced with this:
Can someone label 1, 2, and 3 so I can make the necessary adjustments?
Ta muchly
Jack

I'm just getting major fork dive.
I've sorted the rear shock (which was also majorly lardy) but the front is liable to make me sea-sick if i carry on like this!
I think compression damping needs a quarter (or half) turn, and that should sort it, but i'd rather not cock it up and have a highside!

Compression damping on the front forks is the screw at the bottom of each fork. Screwed all the way in, being the firmest damping.
The screw on top of the forkleg is rebound damping. i.e controls the speed of the return from the compressed position of the fork.
Make sure you set both sides the same.

The compression damping adjustment is at the bottom of the fork leg, the items in your sketch are:
1. Rebound damping adjustment
2. Spring Preload adjustment
3. Fork cap
It's unlikely you will fix this with a tweak of the compression adjustment on it's own. Before you start, make a note of where everything is now, so you can at least get back to where you started from.
Then check the adjusters are working correctly, wind them both full off, bounce the bike, then try full rebound no compression and vice versa. The changes should be obvious. It is possible (if someone has had the forks apart) to assemble them incorrectly, so that there is next to no damping.
If the adjusters make no difference, get the forks repaired!
Assuming all is well, the next thing to do is set the sag, check this both with you on and off the bike. Depending on your weight you may not be able to achieve an aceptable setting(the CBR has quite soft "progressive" springs as std.) If you are "average weight, you should be able to get the spring to support the bike adequately.
Do a internet search for sag / bike suspension adjustment,if your are not sure what you are trying to achieve. There are lots of good clear guides on line.
Now you are ready to adjust the damping, the manufacturers base settings are a good starting point. these should be in the owners handbook. Make small but possitive adjustments, say 2 or 3 clicks at a time and only change one thing at a time. Ride the bike carefully after each adjustment, it is easy to miss something on the road if most of your attention is on what the bike feels like.
A crash will do nothing for the performance of your forks!
If you are not confident of what you are doing, perhaps it would be better to get an expert to help you until you have more experience and knowledge? This is not intended to put you off trying, only by experimenting will you learn. It's just that so much of riding is about confidence that if you have doubts about your machine, it can really hold you back.
