So many #s easy 2 get confused, with the 272 being a 52mm and the popular 372 big bore 52mm, IMO easy 2 think that the 365 is a 50mm. Just my 2 cents, he would be looking 4 a 262xp piston 2 stay with 48mm windowed option.
@@JandSChainsaw What's your thoughts on windowed vs solid piston, when it comes 2 the bottom/base feed transfers? I think velocity would be lost with the windowed piston, trading loss of velocity 4 piston weight
Doc is right. Hard to keep all the numbers straight. It is a Jonsered 630 piston. I was also saying degrees when I should have been saying thousandths.
@@cajun3197 windowed vs solid piston question, with the transfers being on the base and not the side of the cylinder, (example 372xp vs 268xp). In my head, seems you would loose a little velocity with a windowed piston with the 372 style transfers. Does this factor in at all? I know success is being created with the windowed pistons in the 372, 🦎 using the 272 and 266 with great results. His recently built 50mm 372 with the 266 piston is nice!
I believe that is a 268 piston, same 50mm, the 266 piston has windows but the skirt goes all the way @ at the bottom of the piston, the 365 is 48mm like the 61and 262xp, 262xp would be your windowed piston option.
With the transfers being open at the bottom/base of the cylinder verses inside the cylinder, where do you decide or choose solid piston or windowed? Wouldn't a loss of velocity happen with the windowed piston being all open verses the solid? Solid piston would seem 2 me create higher velocity but add weight. Would like 2 see same saw run back 2 back with just a piston swap/comparison, solid vs windowed.
@@Doc-Cole_Trickle-of-Chainsaws on the Echo 550 i built i went with a much heavier piston, has no negative effect on the saw as far as I can tell. If you are going all out then go for the weight savings but on a strong running saw the difference is probably minimal
Dang that was about like physics class in college.....all I remember is short skirt 😂😂
Sounds like a solid plan! Love it when you go deep from time to time👍🏻
That's what she said.
@@novicelumberjack 😂
I like the plan, looking forward to how it turns out.
When and where is saw fest this year? I can’t find any info on it
266 is 50mm 365 is 48 are you using a 372 topend
Wondered that myself, thought he was staying with the stock 48..

How are you using a 50mm 266 piston in a 48mm 365S cylinder?
Misspoke. It's a Jonsered 630 piston.
I’m sure you will build a nice one.
Thanks for the vote of confidence!

I cant wait till I can afford to play with a 3 series saw. One day. Cheers
It will happen. Seemed like it took me forever to get a 372xp. I remember thinking they were FAR too expensive. Now I've had several
@@novicelumberjack I guess they hols their value well though. Cheers
Perhaps performance gain from windowed piston is from lower weight? (I don't know much about 2-stroke...just guessing)🤔
Thats what im wondering too.
Sure, it could rev a bit freer, but that skirt is letting a LOT more fuel and air into the cylinder.
@@novicelumberjack Okay,that makes sense.
Comment from me today 😊

Hello, you should try a 262 piston, is 48 mm y belive
Wrong wrist pin. It would need the 625/630 jonsered. 61 husky etc
It's a 630 piston. I misspoke. Hard to keep the numbers straight with all the clutter in my brain!
@@novicelumberjack you know all the tricks by now. I figured you just had a brain fart like we all do 😁
👍
Could you just cut the skirt
