250.
Progressive offers a fork spring for my application for $92. Would this help?
EDIT: ordered the progressive springs.
Also: the tubes in the chopper kit are Yamaha '95 Virago 1100 cc.
The Yamaha specs show two oil levels, one for US and one for UK. They also say that "if you hear a clicking noise on rough roads or hard braking increase the amount of oil to 409 cc" (UK model, up from 389 cc)

stronger springs will work... i would try 15 weight... but thats just my opinion... my bike has serious suspension dive when i hit the brakes, it is 1 1/2 from bottoming out... i plan to upgrade the springs when the seals go out... and i will run 15 weight, but i want it stiff as possible..

Id try heavier fork oil to begin with. Im not sure what is stock (maybe 15w), so maybe try 20w. That will slow down the compression a bit.

You can increase bottoming resistance by adding more oil also, but If you do too much you will blow out your seals.

If that doesn't work then get new springs.

That would be my path.

Thicker oil effects compression more than rebound.Smaller holes on the compression damping.

Klotz? (sorry...couldn't resist Roll Eyes

)
Also- I am looking at the damper and there is only one set of holes that function for both compression and rebound.
