Sloppy Suspension

2003 CBR 600RR. Front forks are super mushy and I have them as stiff as they go. Should I replace the innards or go with newer inverted forks? My only qualm with different forks is that I have brand new Galfer wave rotors.

Also, the rear is lowered I think 3". If anyone wants a lowered CBR (I'm 6'), I will gladly swap over for your OEM parts.

Replace and check the oil level in the forks. They might require new springs to suite your wieght. Not a bad idea to check the seals and bushings while you are in there.

As for the rear it should only be the two link plates that make the hieght difference. You should be able to find stock ones rather cheap or cruise flee-bay for a set.

I'll do that. Thanks for the quick reply. About the rear I might wanna get a new spring if it's been compressed that much though.. At least I think it is with the lowering links.

USD does not equal better than standard.
Replacing your forks does not really solve anything.
Get new fluid and the correct springs in the stock forks are it will handle fine.

As for the rear... get it back up to height. It must handle like doo as is.

The links should allow the shock spring to be in it's normal position. It is the length of the link that moves the shocks mounting point lower so the swingarm moves up lowering the bike.

If you are looking to spend that kind of money on your forks drop them with a pro rep in your area to rebuild them and set them up for your wieght and riding style. the cost should be comparable and you will know the forks are built correctly and will get the support of the builder when looking to set up your adjusters.

Don't need to do any valve replacement?

Guess for now I'll just get some springs, fork seals, and oil.

If you want an A1 job..... send them to Mike Fitzgerald (thormosman), but I think it is a waste for a street bike.

Order some replacement springs... Like I said.... I never revcalved mine and tracked it.

Depending on the number of miles and wheelies, it may need more than an oil change and springs but that's the cheapest way and the quickest.

If your planning on doing trackdays , yes - if your just gonna ride around with the ocassional spirited moutina run, new oil and springs will probally cure your woes -
Just courious, you are noticing and weeping on fluid from around any of te adjusters are you ? Ive heard of folks going a bit to far accidently when adjusting thier clickers and actually pushing into the seals in the valving and the like -

No, I don't see any liquid on the adjusters, and the forks aren't leaking. I'm about to leave for Guam and Hawaii in a few days for some military stuff, and when I get back with some of that per-diem, I will get springs, oil, seals, and possibly valves, because I really do wanna take this bike on the track.

I am 170 naked so I think I'm gonna go with the Racetech .9 springs, but I'm unsure of what weight oil to use. Everywhere I read, people argue about it, but I want it to be better for track, but not rock solid. Also for some reason it likes to do wheelies, I don't know why, but I should probably set it up so it would be good for that too.
