EFM autoclutch or transmission problem?

[JoKDX220r]

Hi,
I have a KDX220r 2003 with the EFM autoclutch for about 2 months now.
Last week I noticed something strange when I was on the street, I can't get to 3rd gear.. after 5-6 seconds of waiting rpm get lower then I was able to shift to 3rd.. same thing for the 4th, 5th etc..

I change my transmission oil every 4 hours, I was half way to my other oil change when it first happened.
I changed my oil yesterday but when I tried it today it just do it again..

I only have like 1km on street to do to get in my trails, but I have to make it "fast"...

I wonder if anybody here ever get a problem like that with the autoclutch, it is a setting problem because of the "high rpm" or it is the transmission ?

Thank you.

Probably hi RPM's the trans is under load, try letting off the throttle to unload it when you shift.

After shimming mine correctly everything worked fine, but still I had trouble shifting under full power, I could quickly chop the throttle as I shifted and she'd slip into the next gear pretty easy.
I liked the EFM autoclutch everywhere but on downhills.

Unfortunately after six months of races and trail rides the clutch hub bushing seized ruining the hub. Luckly I had a spare hub so I went back with the manual clutch.

You should call Garry if it persists.
