TE/TC 4CS/CC Fork length

Hi,

Can someone please give me some advise on suspension set up ?

I replaced the 4cs forks on my '14 TE 250 with a 2nd hand set of CC forks.

The 4 CS forks measure 932 mm and CC are 940mm.

The factory setting with 4 CS was 2 lines showing but bike felt unstable hence set flush - I'm running the CC with 2 lines showing hence on a like for like basis my current set up is 6mm different.

I don't feel the bike turn well at all in this setting i.e. its a real fight - great in straight lines etc but otherwise handling is poor.

Appreciate solution maybe is to simply raise forks in clamps by 6mm. What is making me think otherwise is that i understand '15 & '16 4 CS forks were 940 mm ....and they run 2 lines

I have adjustable triple clamps and running 22 rather than stock 20.

Most of riding is tight woods....

Any help / ideas apprreciated

Start by setting them at the height that the SAG comes out perfect then adjust to your preference when you ride.

I've got a mate that has made the same fork change.
He runs the forks a looooooooong way through the top clamp as the CC's are a lot longer.
You want to make the measurement from the clamp to the axle the same as it would be if you were running the 4cs.

Indeed, means will have to drop min 6mm.

Guess that's it felt riding bike was like driving a bus !

Any views on whether to run 20 or 22mm offset ?

additional math and full documentation is really required, you need to run the numbers, axle position, offset, length, rake , trail. its all about the dims then you need to balance the front to rear for weight transfer with fork projection, rear sag, spring rates.
you just did a possiblel good thing mod but you need to educate yourself on suspension and chassis set up, you asked for it now its in your lap.
Its not all in front....rear sag, rear comp and reb setting rear spring rate also have alot to with how your front is doing
its the entire chassis layout, and thats has taken years for chassis guys to master, read some Race Tech pro circuit and other top tier guys tech info.
