the last one was a monster. I remember Andre literally putting his knee into it. I bet this one's gonna be even stronger!

My mate that bought that last 660 still won't shut up about how fast it cuts. He does not regret selling his 880 one little bit. He's even been felling trees for the local council and even they've commented on it - all he has run is a 25" bar and Carlton Semi Chisel Skip with an 8 pin.
 
Well this is going to be interesting now. It'll be good you get a 660 to go up against the 390s. It'll be hard for the 390 to catch up with the BB kit with the cc disadvantage.

Yeah I have a feeling with a modded BB kit it will be getting close to my 3120 with bars maybe up to 36".
I have a feeling I'll end up selling the 390XPG - oh and changing the 660 studs to 9mm :)
 
I prefer flat, but really makes no difference. Was more curious than anything.

I'm getting Brad to have a good look over the kit but I have a funny feeling it'll be the same MS660/066 BB kits as sold by everybody else in the world.
 
I'm glad to see you're giving the 660 another chance. The BB kit that I have on my 066 right now is the first 066/660 that ever really wowed me. Don't get me wrong, they all run well, but this gen of BB kits runs awesome. Mine doesn't have a popup either, so yours may be just that much stronger. Your saw is ordered and should be here tomorrow.
 
Cool :D I hope the piston is good enough. The whole setup is excellent. Even a better finish than the factory P&C from the last 660. These little Chinamen are getting pretty good. I also got a couple of 372XP BB kits with a good finish. Very impressive. Not Mahle impressive but pretty damn close.
I'm in for the pop up if you and Brad are!
I look forward to seeing Brad's write-up on this mystery BB.

If it is the same kit as sold by Bailey's, then a pop-up may not be an option. The top land is not that tall, and the bore plating does not go all the way to the top. The new Bailey's kits have good compression in stock form, anyway.

I think there is another brand of BB out there, though. You see them on the bay from time to time. Possibly Golf ? Also some of the older generation Taiwan kits still on the market.
 
Thanks for the replies guys. If these photos of the actual MS660 BB kit being used ring a few bells with anybody then let me know. I'm sure the guys that have seen a few of these kits will be able to tell if they are a common kit or not.

Do you have a pic of the combustion chamber?

Sorry Brad I don't have a photo. At the time my phone camera wasn't good enough to focus properly. I do have a 372XP BB kit here though. The other few kits I had are now gone.

Matt can you do us a favour and measure the skirt width?

Sorry Al no can do mate. The other 660 BB kit was posted to Aaron (porky616) yesterday. You might get your 372 BB kit today :)

The latest 372 BB kit looked the same but I find it hard to tell if it's lacking nikasil or that it hasn't been honed to the top.

I have had it turned by .025 thou, .018 squish so we will see how it hold's up.
