Crf 450 front preload adjustment

I have just bought a crf 450 (04 model) and i feel that the front preload is set to hard . How can i adjust this, is it the big nut under the bottom of the fork?? And how much 'static sag' should i set it at . I thought about 55mm is a good start for dirt bikes, but i am a bit new to the dirt thing

    Yes , i have actually done the same on my road bike. But the Crf has two small screws on the top of the forks , one of these has soft and ******* it. i thought this was for compression damping. The other small screw has nothing on it and sits off to the side a bit. There is another small screw on the bottom of the forks and these have soft and hard marked on them as well. Are the ones at the bottom rebound damping??

    Where is the Preload adjustment??

    Thanx , a bit confused, never had anything with upside down forks.

Hi ...... Any preload and/or damping will be adjustable from the top of the forks (even upside down forks). Anti-clockwise to reduce, clockwise to increase. You may find that a previous owner has increased the 'weight' of fork oil as a cheap/easy alternative to adjustment or aftermarket linear or progressive springs.

04 crf 450 starts hard most times we have to push start it but after that it starts fairly easy.

crf honda's run titanium valves which wear out very quickly if valve clearances not checked very regularly. what happens is the valve wears on its sealing face and clearances close up and then valve rides and looses compression,much like a leaking tap. bike will make more compression and valves will try to seal when warm. i probably rebuild one of these bikes a week with this problem. get it to your dealer and have clearances done. you can get stainless steel valve conversion kits which are much cheaper than honda titanium valves.

What are the compression settings for a 2004 (rider is 230 lbs), and 2006 CRF R (rider is 235 lbs)?

Compression settings are adjusted in conjunction with rebound settings AFTER the rear spring pre-load/sag is properly set. The springs on both these bikes are too soft for 230-235 lbs. so they would need to be replaced with the correct stiffer spring rates to properly set sag for starters. You can work around this by attempting to set sag near the ballpark and then compensate for this by adjusting the clickers. This requires you to adjust your settings the way pro tuners do - trial and error.

I need to rebuild my 04 CRF 450R front forks

The best way, is with the manual that comes with the bike new, if you don't have it, find or borrow one (Same model and year) because it has all of the steps and fluid capacities in it. There is no way to "talk" you through it.

Have the dealer replace the worn chain. On this new of a bike I think the chain may be okay. Ask the dealer if you are adjusting the chain properly.
