Hi I'm new to the forum and needed some advice on a 87 254 se I'm new to cutting and had the saw for two weeks and love it my only problem is when i start to cut 8 foot section into 16in the saw heats up quick. I read that the 254xp has air injection would i be ablr to upgrade my saw and what would i need. Next question is to cut my 8foot sections is it better to upgrade to a bigger cylinder to have more power. I read if i change to a 265 crank and cylinder it would work. but would i need a bigger carb, piston rod, top case. thanks for all the great info
