Brad, for some reason, the 660 in the attached video looks awfully familiar :msp_biggrin:

Now after reading through this whole thread, you have me intrigued. Going to go pick up a 562XP later this week....do I need to just go ahead and get the old lady REALLY mad at me, and grab a 390 too? Wouldn't mind having something else to compare to the 660 :dizzy:

Well thats a stupid question, of course you do, but you should make it worth your while and buy the saw send it to Brad for porting and then tell her.:msp_w00t::msp_biggrin:

Well, I basically did that last week when I sent the saw off to Brad. Actually, it was worse- I didn't tell her at all. The girl she's friends with that does the bookwork at the saw shop told on me unknowingly:bang:

My out was to explain how much money the 660 would save on the current construction of our house by being able to make siding out of the oak and pine logs we have left from the site clearing. Then at least I had an excuse for the Alaskan Mill too :D

Haven't done much cutting since clearing the ~6 acres on our property roughly this time last year. About 3 more to clear this year, plus deal with some of the leftovers from last. So, I've been on a bit of a buying spree, and she's pissed off.

I'm glad to see a number of people jumping on the 390XP bandwagon here and giving them the credit they deserve.
Brad has built a couple of 660's for me and a 390XP (plus 3 x Dolmar/Makitas) and I'd take the Husky anyday over either of the Stihls. I'm not sure a hopped up 390 will outgrunt a similarly hopped up 660 but there are a number of other factors to consider. The two main ones are balance (big win to the Husky) and fuel economy (massive win to the Husky).
My ported 390XP uses about 60% of the fuel (at most) of a stock 660 doing the same work. The MS660's are a fuel pig to start with and even worse when ported.
The last pop upped and ported 660 Brad built for me was a weapon for sure (32" bar, 8 pin, + aggressive non skip chain was easy work buried in our hardwoods) but the 390XP was a lot nicer to use even though it could only run the same bar and chain combo with a 7 pin.

Looking good Brad :cheers:
 
I got my 32" Tsumura light bar today. It's got a loop of Stihl semi-skip square ground chisel chain on it. Thanks Mike!

Here it is with it's nemesis. It's really not a fair match. The 066 is a BB with 99cc, and it's a very strong runner at that, perhaps the strongest I've run. It's wearing a new 36" Light bar and full comp round ground chisel chain.

Gnarly, absolutely gnarly stuff right there!
 
You going to replace that outer spike?
Maybe you should put slicks on that 390 as punishment for dropping that tree on you.
 
Brad,

In your vid of the Husky you wrote, "Thats all the clutch can take".

What does that mean? Is it slipping? Are you concerned about mechanical failure?
 
Man, I love my Stihl Light bar. IMO, Stihl really knocked it out of the park with their Light Bars.
 
You going to replace that outer spike?
Yes. I just haven't ordered it yet.

Brad,

The chain is about to stop and the engine's still revving. It's to the point of slipping.
 
are my eyes playing games or does that 066 have the carb off a yamaha banshee and a pair of toomy pipes for exhaust ?
