I have a Stihl MS 211c and was wondering if I can change from green to yellow chain and also, would I have to change out the bar and or sprocket? I have been running 3636 005 0055 63 PM3 55 green chain and was thinking of going to 3617 005 0055 63 PS 55 yellow chain. I mainly use this saw on brush and small stuff. Would performance be better?
