I have the same issues and everything is fine on mine. Been a pain since everything (Motor, Tranny & Clutch) was new! I run Redline Synthetic in mine. It's still a bitch to find. But like others have said, it is easier to find, coming down from 2nd.
Come into neutral from second on your slow down for a light at slightly higher RPM's.... Your bike doesn't want to go into first on a downshift and will stop at the neutral position... something to do with the way the gears are sync'd...I've been doing it since I learned to ride with no problems....
Not sure if that's a clear explaination, but it's the only way I can explain it.
Don't feel like the Lone Ranger- I've got the same thing on my 07 RKC. Had it on my 03 RKC also. I think it's just one of those things you have to get used to. I'll be trying some of the tricks mentioned here to see if it helps.
You really should not be trying toshift your trans while not moving. Meaning shift down from 2nd coming to a stop. Clutch drag and just the design of the trans says bestnot to shift while not moving.
I had the same problem with my bike. I had my hot and cold idle adjusted to idle at 1000 rpm and I haven't had the problem since. FYI I wasn't trying to fix the neutral problem when I had the idle adjusted it was just a benefitwhile correcting another problem.
