Default CR250 front forks very stiff?????

     

Hi,
I had a big off a while back, after this i had the forks rebuilt. Before i put the forks back on they were working perfectly. After a few rides with them on, the forks started to become very stiff. They didnt compress smoothly or easily. They almost felt as if they were dry or bent?????

Could anyone help!!!!

Aron

Forks are off a 2000 cr250

Not much to tell with a guess??? You'll have to take them apart or take them to a shop to see what's up.

When you had them rebuilt did they check the inner and outer tubes with V- blocks and a dial indicator for trueness?

i had that issue, theres a screw on top of the forks, one of them (probably on the side of the cap) is a air bleeder. take it all the way out and you should hear air hiss out. it happens with these forks.

When you let the air out of your forks do it with the front tire on the ground... If not you will create vacuum. When I rebuild or service any of my forks I do not have any increase in stiffness unless the person who filled yours did not burp or purge them? the rod must be pushed to to max extension and compression when filling cartridge type forks... this burps them as you do it you will see the bubbles rise to the top as this happen you add fluid till you get to your desired level... Fluid levels oil weight and spring rates are very personal. If youu have over tightened your fork tubes in the tripple clamps that will lock them up or impare their ability to freely travel. I torque mine to 14 ft lbs and check before each ride...... If you suspect your tubes are bent from the crash you can do a simple roll test on a level cement floor. Did you center your front wheel when you put it on your bike? are your fork tubes even in heigth in the tripple clamps, hope this helps.

Sure you could.... but i like to know why stuff doe not work as its designed... how many CC of oil do you have in your tubes, what is your spring rate KG? What was the torque in FT lbs on your tripple clamps.... where they over tightened and do you have a bent fork tube from that....

Besides, when buying this older stuff you are not always guaranteed you are going to get anything better.

Forks/Shocks are service items. They need to be serviced to keep working as they should.
