On my F3 the rebound adjuster is jammed. Its cheaper to buy used forks than to buy new adjuters (about $170 each). I want to research putting a F4 fork on my F3. This would give me bigger calipers and a compression adjustment.

I need someone who owns a F4 to measure the length of the fork from the axle centerline to the top of the fork tube (not including Preload and rebound adjusters).

I know the triple tree would have to change.

Thanks

You can also use F4i forks. F4 & F4i forks are externally the same.
