General info about forks - March 29, 2018, 09:30 AM

2000 Ninja ZX6R and I've only had a shop recommend replacing the seals once around 2004.

I put zip ties on the forks and I have never bottomed out the suspension, maybe two inches away from bottom. I've taken it to lots of track days and never had any issues with ride and feel and it handles great.

My question is how often should I have replaced the fork oil and at 220lbs, should I change the stock springs or get new ones due to age.

I've never put more than a couple hundred into this bike besides oil, tires, spark plugs, and a filter.

I think I'm willing to spend some on upgrades if necessary, but I'm more of the ain't broke don't fix it side of things. I don't mind doing work myself and I'm comfortable ripping the bike apart as long as I don't need hundreds of dollars of special tools.

Thanks for the advice!

From a personal standpoint, I've always serviced forks around the 20k mark for mileage. I probably wait too long. When I dump the old stuff it smells torched. When I ride it after doing the service is feels noticeably better.

Springs don't typically wear out. I'm of similar weight and have had good results with stock springs in some bikes and better results with springs more matched to my weight. Sometimes I don't like the aftermarket springs. If you are doing the service and work, I'd spring (ha!) for the springs matched for your weight and swap them out. If they aren't to your liking, you can swap them back and sell them.

I find that a proper suspension setup only comes into play when you start pushing a little. As long as they are not gone and the bike is bouncing around you're the limit, not the forks or the shock.

If it ain't broke, don't fix it....

After a few years of track riding, I feel like I like how much/how little play the bike has at the track. Any softer in the rear from full stiffness and I wheelie too much coming over the bridge hill and carousel at Shenandoah. When I wondered if the front was too soft, I thought to check it and it really does seem fine.

After 18 years, this bike still holds up and is amazing for me.

Suspension specialists will recommend changing the fork oil at least once a year. I honestly think that's a bit much unless you're a super quick rider around the track. I try to change it out every few years for a bike that sees track time. I'm much heavier though and aftermarket suspension is my only option.

That being said, if you haven't changed your fork oil in 14 years you definitely should.
Cause remember, you will adapt to the limitations of your machine and feel like it's fine but it could be much better.

I like to do a general all-fluids flush every 2-3 years.
Fork Oil, Brake Fluid, Coolant.

If you're tracking it occasionally, reduce the service intervals to 1.5-2 years.

If you're tracking it often, every year.


Springs are not needed unless you feel you're weight and riding style is approaching the max of what the current spring rate can handle.

Its def time for an oil change, but you will need to recheck your set up and your suspension adjustments after.

Thanks,

Yes you should definitely have the forks and shock serviced. Also you need to soften up the front end some. I would bet you should have the bushings in both front and rear replaced.
