Bark box carb adjustment

[Henry Lee]

Just bought a bark box to stick on my 880 for a bit of extra power and was just wondering what kind of carb adjustments will need to be made and if anyone has done it before too

I would be more concerned that your ear defenders may need upgrading!

Extra noise you mean

I have a sneaky feeling it takes a bit more than an extra hole or two in the exhaust and a wee twiddle of the mixture screws to get more power from a 121cc stroker

You would be surprised- engines are often restricted with smaller muffler openings for emissions. Dual port mufflers are available from Stihl directly for some markets where emissions are less of an issue
