2001 shim stack

Recommended Posts

We were changing seals in a freinds 01 cr 250 and we wanted to look at the shim stack. These forks were supposedly revalved at at sometime before he got the bike. He has never really liked the way the forks work. Would like some opinions of this shim stack.

2-20x.1

19x.1

18x.1

17x.1

16x.1

15x.1

14x.1

13x.1

11x.1

10x.1

9x.1

8x.1

6-16x.3

How much does he weigh? What springs are in the bike? What type riding is he doing? What skill level?

That stack looks like someone was guessing at what might work.

the suspension was said to be done by one of the major companies. (PA) abrev. whether it was or not we are not sure. the guy that owned the bike only rode mx I think and was supposed to be for a 200 pound rider. the springs have no marks on either end so I can't tell what they are. does this stack seem like it should be stiff?

That stack appears to be for blitzing SX whoop sections for a flyweight rider. I've seen some really bizarre stuff from a company that goes by the initials of PA.

so you mean the stock stack looks like for SX...

I thought he was saying the stack has been stiffened.

and yes, back then I also removed some of the HS shims

@osobad:

the 6 16.3 act like a backing plate. so if there's a difference its the 8.1 clamp shim, which is supposed to be a 8.25 stock (listed here on TT in another thread)

correct, yes.

I would place the 11 and 13 shim underneath the 8mm clamp shim to eleminate a possible HS restriction.

Sorry, the lack of low speed shims looked a bit weird. Didn't remember them being that screwed up off the showroom floor. Then again, Honda was still learning back then.

if low speed shims were added would that not make it stiffer on the roots , rocks ect?

If added to that shim stack, it would be very harsh. But that stack itself would be harsh, all other things being equal (mid-valve, oil volume, etc).
