Hi Everyone,

I Just got a CRF450, I had 2 run with it. My last run started to be a problem.
So it seems that I wasn't able to Un-clutch, starting the dirt bike and lever pin down. Pass the first, and the bike would turn off directly .I thought it was a minor issue, so I replaced the clutch wire and re-adjusted it. Start it again, pass first or second at no speed. It turned off automatically. I opened the disk casing, checked all my disk they seemed fine, no cracks or wear on it. I did put the bike on the first gear, and try to un clutch and push the bike... I can change the gear, but can't move the bike while pulling my clutch lever. I never felt with the bike yet...

I don't know where the issue comes from, it is my first dirt bike I used to race Z750's and had someone taking care of it.

I have all the tools for a full service, but I'd like to know what you think and what should be done.
I believe it's not disengaging when I pull the clutch lever.
Springs? SHIFT DRUM? SHIFT FORK? or something else.

Let me know, I'd like to get it ready for the season.

Kindly

Welcome to the site !!

First you failed to mention what year the bike is

More info is needed on how the clutch feels at the lever , does it have good consistent resistance when you pull it ?? , or does there seem to be a lot of slop or free play ?? , or any binding ?? , how does the cable look ?? , is it frayed in any exposed areas near the lever or actuator ??

If its not disengaging with the clutch pulled with the engine off and in gear , it could be a few things , even a cold engine can do this , though the bike should move , it will have some drag , but the wheels should spin freely on the ground , even on loose dirt , after the engine is warmed up , the clutch should be able to be pulled and the bike move fairly easily with it in gear , but there will still be "some" resistance , first i would remove the cover again , and look very closely at the clutch basket itself , if it has notches like in the picture below , then the basket is worn and needs replaced ,the surface showing in the picture where the clutch plates set between each post should be smooth without any ridges , as that will cause the clutch to "drag" or "grab , the other could be adjustment of the cable , either at the clutch actuator or at the perch or on the cable adjuster itself (the cable adjustor is near the lever but on the cable itself) , also you need to check the Steel Plates and the Clutch plates and make sure they are within spec (if you need measurement tolerances i can post them) , also have you put the bike on a stand with both wheels off the ground and checked to make sure the wheels are spinning free with the engine out of gear (neutral) , to confirm the brakes are not dragging and that the wheel bearings are not bad , as either of these could cause excessive drag

This is what a Worn Clutch Basket looks like , those notches === (like that) are not supposed to be there , that area should be smooth :
EDIT: Replaced Photobucket picture with IMGUR picture so it shows up now:

Hi, I was just wondering if yo could post the measurement tolerances for the clutch plates on a 2006 crf450r, thanks!
