I've been experiencing the same thing with my '04. I thought something may have been wrong and I'm glad to see I'm not the only one having this issue. I'll try rocking the bike back and forth next time but I too found it's best to try and downshift as you're stopping.

 

play with the clutch when it happens, let it halfway out then push it back in, all the while trying to shift. works 100%

 

+1. I get this a lot too. Release the cluth a little bit and she'll slip right in. I have the same problem with my car when trying to get it from neutral to reverse.

 

Becareful when you say 100% haha. I've tried that. It didn't work for me.

 

Yea rocking back abd forth makes you look like an idiot. Just let the clutch out to where it starts to slip while pressing on the shifter and it will click right in. Happens alot its normal
