done one on a husky 365 special....practically brothers...torque increase from bolt on was big....since then modded the muffler, sounds like a stihl now..wired but kool, and widened the exhuast and intake, raised exhuast some and lowered intake some......screamer....still dialing in the carb, being conservative till my tach gets back..... but 28" bar and full chisel square tooth, chews through it like butter... soft woood, buried, it goes through it before i know what happens,...oak...still fast, but can't push on it too much without loosing good speed...
only thing i miss was the lower end torque i had before rasing exhuast, i was thinking about going to a 32" at that point., i could push on it pretty good, but know i have to let it eat through with just some casual manuevarin of the hands...don't get me wrong, i can still push on it, it just cuts much slower....
question i have after doing big bore mod...can a saw still be tuned by ear(four stroking) with a moded muffler, and what size bar should a decent moded muffler mod pull???
is there anything i can do myself to get it to pull and 8 pin at 28"? and can you lighten the 372 big bore pistons??
***if someone has lightened the piston on a 372 big bore, could you please post or pm me with atleast one good picture of what was done, i would greatly appreciate it***
