Angel, you can dress your bar with a file, to true it up. If the groove is worn to wide that can be closed up with a metal block and hammer. Just do it slowly and keep checking it with a feeler gage. CSW

I got a question about the SXL muffler. What would happen if I removed the baffle entirely, just leaving an empty case? I know I would have to tune the saw a bit richer because of the increased gas flow, but would it hurt the engine due to lack of back pressure? I know it will make the saw louder, that;s kind of the point.

What are you trying to do - make it sound like an Old Zip? ;D I doubt it will hurt anything, two cycles don't need back pressure. A lot of older saws had less than that! The very early "C" had a cast aluminum block with about 5 slots cut into it. Gee they made a lot of noise at 6000 rpm

Angel, the muffler on that saw is not very restrictive to begin with. Normally the reason that mufflers are gutted and the exhaust outlets are increased in size is to increase power output, more noise is just a byproduct. I've always heard that two strokes do need a small amount of back pressure or idle quality will suffer. The standard rule of thumb is make the outlet 80-85% of the exhaust port window. that should provide sufficient back pressure and a lot of noise. On AS 2-3 years ago, someone posted a pic of a bar-less Stihl Contra with a megaphone pipe specifically designed to make a lot of noise at European sporting events. CSW
