Yeah, that saw is a perfect candidate for the big bore. Should have quite a bit more power over stock, because the saws before 1485xxxxx had a different port design, and thus had something more like 5.0 hp rather than 5.4. Then add on a bigger bore, and you'll be logging.
Sooo, after all the remarks on hp for the 044 today, I called stihl with my Serial# and asked them about production, years made, hp etc... I spoke with a dude named Mark from there. He said only the saws made before 1994 were less than 5.4hp. They stayed 5.4hp from '94 until they went to MS440, which they say is the same saw really with different a different model number and some newer features. Pre 1994 was 129583701, so anything after that was the 5.4hp saw. According to him, the break in the serial number aforementioned was the key, hence the different porting or carb stuff they did, he wasn't positive about exactly what they did different. But also said the earlier ones were 5.3hp. Also, by mfg area, the 1 means made in germany, the 2 means made in U.S. and the 3 means made in Brazil. Just a little FYI for everyone. I've got more details about the 056 if anyone is interested also.
Also, If I remember correctly, he said that the cylinder size went from 48mm to 50mm, that was another difference. I'm calling them back, I love talking to those guys, they are really helpful and friendly.
