Because it is cold, and accentuates all of my past injuries. Besides, so many people here seem to suffer from seasonal amnesia, and can't drive worth a fugg in snow.
Same here on the drivers. Then they drive slow after the roads are clear. Now whats really funny is the tweakers ride their bikes in the snow lol.

And yes they are tweakers cause who else rides a bike while smoking a cig lol.

Which cylinder are you guys using for your builds; the Hyway or the Cross? Does anyone sell the cylinder by itself or do you buy the kit and just use the non-pop up piston as a spare?

I’ve got a 290 and 2 029 supers from a buddy that we want to turn into 390 sleepers. We don’t have OEM 390 cylinders so we are looking at AM.

BTW - I put the 262 into some wood the other day; runs nice! Thx again!

Awesome, Glad you are happy with it.
I’d be interested in the AM 390 jugs’ specs.
If you go that route, how about a build thread?

I could do that; going to try to get everything together and do one of them over the holidays when I’m off work.
I've had good results with the farmer tec 390 cylinders.
I built two a couple year's ago good runners they've cut a lot of wood and still do.
And i used 2 390 drop in motors 79.00 ebay jobbies don't know who made them.
Still running good.

I got mine running last night. I used a cross cylinder. The cross cylinder is very nice. The saw does not have a muffler mod yet and it feel very strong. I made a couple of cuts with it in the dark on my snow covered wood pile and it seems like it is going to be a runner.

I built one with an eBay cylinder a while back and it runs very good but the cylinder is no where near the quality of a cross. The plating is very thin on it. The cross look like an Oem cylinder. The cross piston may not work with an eBay cylinder.

My cross pop-up was 10 grams lighter than the flat top that came with the cylinder. I don't see where @Fruecrue weighed the flat top, I thought you did. I'm curious what yours weighed.

10 grams is huge.
My pop up weighed 68.775 grams
Standard cross weighed 70.92 grams

1 gram = 15.432 grains
Are you using a reloading scale?

Snap on refrigerant scale.

Mine was 60 grams IIRC.

No worries here, bruh! After selling OPE for the last year and some change, I'm pretty well desensitized to the "blade" reference. Unless of course it's the customer wanting a new "blade" for his (model) 20" Stihl......



I'll run a 28" and full comp on mine this week, and report back. That's the same set up I run on my 461.

Long bars are even better when you're older, and very busted up.

It’s been a Week My HeBro.
