Default ZX7R Suspension Setting Questions....

2000 ZX-7R

A friend of mine helped me change fork seals and put fresh oil in the forks. We did this with the forks off the bike. I am 99% sure the fork oil level is correct. Now the Front Suspension is Extremely Stiff. Stiff to the point that it is giving me an unsafe feeling when riding it.

I did a search here and found some info, along with this great link.
Suspension

I was wondering if anyone knew right off hand what kinda settings would be a closer match to my size. Maybe save me some tweaking. I am 6' tall and weigh just at 200 lbs with my gear on.

I am not sure if the issue is even the settings on the forks, however I figured thats the best place to start. If they are right on the money then I obviously have other issues....

Any input would be greatly appreciated.

Setting are right on the money and the forks are tight as hell. I jam down with all the strength I have and the forks compress maybe an inch.

any thoughts?

If anything. with a rider of your size, you should have to increase your front and rear preload settings. Sounds like something is off.

When you and your buddy were done did you bother to get him to help you check rider sag? Would have been a good idea while you had him there.

He ran short on time. Helped me take them apart, change seals and get them ready for the fresh fork oil. If I remember right I put 550cc of oil in each fork.

Way too much fork oil. Max is 435 when the forks are bone dry.

Will that might be the issue, I just cant remember for sure how much I put in the bike. I do remember i had to buy 2 bottles of fork oil because what I was told to put in each fork was more than one bottle held.

If there is too much fork oil in them, would that make the forks extremely hard to compress?

Yes....it's not the ONLY possible cause but it sounds very likely.
