CBR Forum - Enthusiast forums for Honda CBR Owners

Well, the "ERIC" went off to get the suspension overhauled after having it looked at at a recent track day on Saturday... I was thinking now I'm getting pretty rapid, that it's all just too soft and sloppy and dips wayyy too much under hard front braking... however the suspension guys conclusion was:

The fork oil is original (1999) and as such is rubbish and barely even oil anymore... (I've not changed anything on the forks, I bought bike 2 years ago on 8,300 miles and it was soft then, and previous owner never changed it... it's now on 22k miles)
Couldn't adjust the front forks due to this, no matter what he did, basically he reckons it's all just blocked and needs refreshing hence adjustment made zero difference... bouncy as hell (I watched him do this and can vouch for it)
Tried to adjust rear, no gas so everything is relying on the rear spring...

So, over this weekend/next week the guys will do all the usual and give everything an overhaul.

However, the bike has 22k miles on it... so, question is, is it worth changing the springs in the front forks and the rear spring, or will they be fine? How long these parts normally last for?

Plus, if I replace these while all suspension is being looked at, would upgrading the springs be noticeable on such a bike? Any advice?

Also, I'm planning on a lot more track days as well as road biking... got one coming up on 12th August again.... however just not sure what make of springs to go for or just go OEM... I know nothing on bike suspension :-(

Any help here guys? So, do I replace all springs with aftermarket and if so, what will give the best adjustment range and quality without breaking the bank?
