Recommended Posts

Hi

 

I´m a rookie in this area, have patient with me;-)

I wont that it goes smother over roots and rocks. I guess that it has to be faster in high speed?

You have shims stuck together , they will all be 0.1s , what bike is this ? Mid valve standard ? Oil amounts and spring weights ?

Hi

 

I´ve checked the stack to day. You mog was right, some of the shims was stuck. The bike is a Honda Crf250r 2011. The springs is one 4.4N/mm and 4.6N/mm in the other tube. Oil amount is 200 in inner and 300 in the outer. I´m greatful for the help I get.

So it locks like this.

For roots and rocks you need it much softer , you could remove one face shim off the mid for more float and a softer stack and say 7 face shims from the base and try that

Also remove some of the 24X 32 x 0.1 shims from the base valve. Mog said 7, which would be 17 total, seems like as good a starting point as any.

If that's not enough you could look at 2-staging the base valve, but these changes should be a big improvement.

Thanks for the advise.

I´ve now removed 6 shims from BV and 1 from MV. 

200cc in the inner tube and 300cc in the outer, 5w oil.

I tested yesterday  on a sandy track with deep whoppis and felt a big diffrens.  The fork did not bottoming, but felt a bit too soft. I have comp on 8click, but i want to test on the rocks before  do any more changes.

I´ll test the changes on saturday on a very stoning track. 

The 2-stages BV sound intresting.

If its a bit soft in sand it may be still too stiff for rocks , sand requires a much stiffer setup

Correct mog, it was a little bit better but still felt stiff. It felt like the fork worked low. I'm Wondering If the HS in BV can help, what do you think? Or and one else; -)

Any way, it was a Great ride:-)

No, it didn´t bottom. It was a great diffrens to the better.

But it still feel a bit stiff , when the speed i low. I have 8 click out on comp and 12 click out on rebound.

I hop that I get time to test more some evening this week. I wont the fork too stay against wopps and swallow the sharp rocks, roots mm is 2-stage stack someting that is required then?
