Am I being silly? 372 on a 16" bar?

[Reddog]

The 8pin/7pin ? really comes down to how a cutter uses the saw.

If you like to dog the saw in and pull the 7 pin is usually the better one.

If the saw has good torque, the 8 pin can be a lot of fun.

Just watched a vid of a guy stateside running a 372 on a 16" bar, I'm guessing with an 8pin sprocket as well and he was flying.

 

I know they run an 18" fine but a 16" would let me use it for coppice work, but I think my arms may be a little longer by days end with the weight of it.

 

My 372 was originally supplied on a 15" bar and chain set up, from memory it was a option from the catalogue in the choice of 3 bar sizes recommended for it.

What is the difference running a smaller bar on 3/8" chain or .325 ? Some of the 60cc+ saws I've read about seem to offer either alternative.

This saws also got a big bore kit on it with a supposed 90cc. Guess that I'll be having a big smile on my face tearing the trees down with a small bar

 

Big bore is 77cc's ish. Here is a big bore ported a bit hot on a 2165:

 

18", 8 pin, stock chain, in a maple that's been sitting a while.

If it is a BB kit, I would highly suggest using a meteor piston and caber rings. The kits piston I have seen had more tolerance than I care for.

I figured it sounded a little to much of an increase in power.

You running full chisel on that as it's flying through that maple.
