01 YZ125 V-force reeds

[jayson_waltz]

I just got my YZ last fall and only have rode it a few times, but I already want a bit more power. I just put on a FMF Shorty silencer and recently bought a V-Force 3 reed valve. My question is, does anybody know if i should change my jetting with the new reeds? I know Boyesen says to go from a 460 main to a 420 main with thier system, but i don't know if it would be the same for this system. Don't have much of a chance to ride and check it here in the winter b\c the closest indoor track is 45 mins. away in canada and i don't have the tools up there to change jets anyway. Just wondering so i don't blow it up, i have bad luck with 2 strokes doing that. :think:

Thanks in advanced!

On a previous YZ250 no change was required. In your example Boyesen went leaner, no worries about seizing if your rich...
