Id had vforce 2's in my polaris for over 8000 miles and had no problems. I might go with the vforce 3's in my viper just because i found a deal on them. I Think they only improve throtle response a little. All in all i had zero problems with the vforce reeds on my xc 700 even after 8000 miles they still looked like new when i pulled them out.
The stock yammie reeds work great & you won,t gain squat by changing em in a stock motor.

I know of 2 people that went away from stock reeds, and all they noticed was they used more gas, that's right, more gas with no noticeable power gains.
