If you want a quick cheap reversable way to tame down these bikes, look into adjusting the preload on the powervalve. it's an external adjustment (takes about 60 seconds) and you will notice a big big difference in power delivery. You can increment the preload for your likes and riding conditions. It costs nothing. As you gain a better feel for the bike you can gradually set it back to where it will scream off idle.
I found that lessening the preload on my bike caused it to run a lot flatter and smoother at lower rpm's. It just plain runs slower and won't really take-off from under you.
If you don't like what you feel out of it, just take another 60 seconds and set it back to where it was.
I'm pretty confident you will be happy with the results if you take a little time to find a good setting for yourself.
Good Luck!!!!!!!!!!!!!!!!!!!

I can make the RM run like a enduro bike by going an extra 1/2 turn "in" that increases the pv spring preload. Most of the hit riders feel with a 2 smoke is the pv opening, so delaying that, will also lessen or smooth the transition.
Also, most riders have very good luck with flywheel weights, to calm the hit and add traction.
It may be possible that you are lighting up the pv preload so much that the pv opens right away?? If this is even possible, it will kill any low end power, like a stuck open pv. The wrong way to go about smoothing the power IMO.
