So i'm a bit OCD when it comes to maintenance and such but since I bought my bike used I don't know when the last time some stuff was done and am left to visual inspection.

When I bought my bike the front was raised, and I recently lowered it back to OEM. The stiffness doesn't feel right at all. My buddy has the same bike and the front is a lot more stiff. I checked the forks and I don't see any signs of leaks at all. What would be a good way to determine if its time for the springs and seals to be replaced?

 

Springs should be replaced with a pair that is set up for your weight and riding needs. When they are apart, replace the seals so you know the front end is sound.

 

im no expert but if the front feels like its to squishy and you want it stiffer you shoud have two almost screw like adjusters at the top of the forks. if they are adjusted all the way to the h side i would consider new forks. Look to the other guys but that is my opinion.

 

I wouldnt replace the forks unless they were bent. But what I would do is rebuild them with RaceTech straight rate springs for your weight and the recomended fork oil along with new fork seals and bushings. Might not need the bushings. A fork rebuild would make a world of difference than how it is now, guarenteed.

 

Springs don't wear out, you replace them when changing the setup, not because the front end feels squishy. If you friend also has an F4i and you like how his feels then change your settings to the same as his and see what happens. If that still doesn't do it change the oil and make sure its at the correct level.
