Nose sprocket from 11 to 10. A problem?

[Bob_z_l]

Hi,

If I change the bar on my STIHL from an 11tooth sprocket to a 10tooth jobbie how will it affect the saws performance?

I always use official parts and the saw has the 10tooth bar listed as an option....

I think all it means is you will have a slightly smaller nose radius . Could affect kick back potential possibly ....Chain speed wont be affected as that is dictated by drive sprocket .

That makes sense. I had it in head (motorbikes) that it was like changing gear ratios.

Think what happens when you have a hard nose bar ......No teeth at all !

The 11t nose will bore cut a little better, and the 10t will have a little less kick-back potensial - your choise, never mind the recommendations, as those are more thaught out by lawyers than by sawyers!

Nose radius is what really counts, not the teeth count itself!
