I did some searching and it seems everyone goes the other way from 325 to picco (ms261 Stihl Performance kit).. but is there any way to go from picco on my 211 to 325? I asked my local Stihl dealer and he tried to help, but said that he didnt want to give me false information. He believes its possible using true Stihl parts. I plan to run a 16" bar and 325 if it can be made to happen - so that all of my saws will run 325. Makes sharpening and buying chains easy. I know it will cut a bit slower then the picco that comes on it - and I am ok with that. Its not a race for me. Any help with PN# would be greatly appreciated!
