1990 Honda CR250 fork damper rod bleed hole & shim stack

Recommended Posts

I'm in the process of rebuilding a set of Showa forks off a 1990 CR250 and noticed one fork damper rod has an extra shim in the rebound stack and the bleed hole on the wrench flat at the base of the damper rod was opened up from stock diameter of .052" to now .078". The other fork damper stack and bleed hole is unmodified.

I'm assuming the extra shim will make the rebound harder (slower)?

What is the benefit of drilling the bleed hole to a larger diameter?

Is this  modification done if a stiffer spring was used for a heavier person?

The compression shim stacks were the same but the shims are triangle shaped, not completely round. Just enough material was left to cover the piston ports. Is this stock or modified?.

Does anyone know what the stock shim stack configuration is for both the compression and rebound?

Thanks for any input!

Extra bleed is used to help the fork move easily at very low fork speeds , you really notice the bleed as its always in use where hs hits are not so often felt

Thanks for the response mog. Looks like this fork was set up for woods riding.
