Some people prefer the Big Bore Jugs.....not sure if these are OEM or AF!

Aren't you a little on the mature side (old):msp_tongue::msp_tongue: for that. Well you may be right. :help::help: they do look inviting.
You're the moober! Can't you just breast feed yourself?!

As long as we have Italian jugs around I don't wanna breast feed myself. :msp_biggrin:
I'm not letting this thread die so fast. Here are some images of the latest Husky BB kit I received:
Transfers - the lowers match the chassis fairly well. The rear upper transfers towards the exhaust side are a touch higher than the front pair; whether purposefully or not. The overall timing for most of these ports are a bit more aggressive than stock.

Looks pretty good, other than the flat exhaust port roof. That's been my #1 complaint all along.
And how long do they run? Anyone out there run these on a daily basis at work? How long have they been working for you what results? I am wondering if the metals inside the bore are up to par and if the bore measurements are proper.

We can't stop here, this is bat country.
It's probably not that flat... just the camera angle making it look that way.
My concern is the dark ring on the top of the bore. Can we get a better view of that ring of death?

Looks bad, I wouldn't want a piston ring anywhere near that.

I agree. The bevel looks pretty good too.
It just looks like the bore isn't as polished at the very top. I have a 372 big bore here that I'll do a unbiased review of........
I've taken .090 out of the squish band of a Meteor 372 jug to see if there would be any problems.......I ran a tank thru it and it's now going on another member's saw for more testing. He has agreed to give us feedback on it whether it's good or bad.
The one I posted is an aftermarket Chinese manufacture 52mm BB kit. It is not sold as a Meteor. I had it imported and dropped ship to Ireland last week direct from China. There are a couple of other threads on it here on AS posted by Aussie1.
The exhaust on it is fine. The upper part of the cylinder feels fine. It's just a tad discolored. These kits have a lot of miles on them so far without any issues. They are monsters once ported. I'll just be cleaning it up some and maybe opening up the ports a tad and adding some timing. But it will be very mild. I don't need it to eat too much of our $8/gallon and $16 quart (non synth) fuel and oil.

I run them on Concrete saws. My language barrier employees can't figure out to leave the air filter sealed and just bring it in when it won't run... it's in the Stihl manual that way. I put a Flyway brand plated cylinder on a TS420 this week. I installed it on the tail gate of my truck in just under 2 hours.. yes I've done more than I care to on these saws. They pull a 14" diamond wheel about 10 hrs of run time a week. I used ALL of the parts in the box including rings, wrist pin, etc. When it goes south.. I'll let you know but it starts, runs, pulls good so far. I even went for a gasket kit made in Taiwan.
The last one went until it was straight gassed. In my case, $100 top ends are much cheaper than OEM that may not make it a week with lousy operators. The other main killer is hung open compression release. They run that way.. for a few minutes. I really should remove them all and install plugs but then they'd whine about hurting there shoulder or something.
FWIW... I've run Ching Chong top ends on Makita and Stihl saws.

Not polished would mean that it didn't get honed? So it's going to be a little tight then. I'm interested in your review, I'll be getting another BB kit soon and I wasn't all too impressed with the NWP kit. It runs well but I had issues with the material and plating.
0.090" wow... I accidentally got the exhaust port of a 288 a little high so I'm taking 0.070" out instead of the 0.040" that I wanted, 167 ex duration was going to be too much. I feel sorry for anyone who pulls that rope without hitting the blue button first.
