I'm rebuilding the top end on my 385. I got a used oem 385 cylinder on the way. I'm going to port it. I have experience porting 2strokes but this will be my first chainsaw job. I've read as much as I can find on this particular saw but would still appreciate your suggestions on the best way to go with it. I don't have access to a mill to deck the cylinder, so to this point this is what I've come up with. I'm going to widen the exhaust and intake as far as the skirt will allow me I'm going to match the bottom transfers with the case and gasket and grind em to make em flow mo. Then I plan to replace the gasket with l something like aluminium to try to get me 20 thousands squish from what I've read u can't just delete the gasket in this saw. Since I'm going to drop the cylinder I'm going to loose some timing on my exhaust but I'm debating wether to just leave or to raise the exhaust maybe 2mm to get that back. I'm not going to mess with the upper transfers because I don't really have the tools to get at them properly. How's my plan sound any suggestions and criticism is welcome. Thanks in advance.
