Very nice Joe, always nice to see HONESTY about building power saws. I'm put off by some other TH-cam saw builders who BS about how many saws they built and how great they are. Cool thing is you show exactly what you do and provide proof of the results. It's very easy to see that you have built countless saws and know how to use a lathe and grind ports to perform the way you want. A breath of fresh air with no smell if you catch my drift. Charlie Briscoe is another honest man that builds a hell of an Echo amongst other models. You have a loyal subscriber in me, thank you for being true to your craft.. Cheers
Thank you, I appreciate it.
Another fine video Joe! I have a old ported 562xpg and it’s been a great saw for me. When I bought it it needed crank bearings. Put new bearings and seals in and it’s been going strong for 2 years. Biggest thing with keeping them alive is a sharp chain imo.
Wow. This guy is a chainsaw genius.
I love your work.
Solid gains thanks for the Monday morning vid.
Going to Try my best to stick with a monday/Thursday schedule. May throw in some short clips, or an extra weekend video
Great stuff Joe. Such a great working saw.
Thank you.
Wow over 6 horse on a 562! Dang. I wish
I could send you mine
Saw looks rlly clean from a broken saw
Nice job Joe!!!!
Thank you
On my 562xp. I just literally cut the muffler all around the seam and gutted it. Weld back together
That muffler has sooooo much metal inside it
Yes, lots of baffles and tubes.
Nice save sir big performance gains to really. Good job man!
Can't wait to see the new 562 mark II run on the dyno and ported.. thats out apparently in some countries
Great job buddy! 👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🙏🙏🙏🙏
Thank you
Great video as always!!
Awesome work sir 👍 love the channel
Absolute beast!
Iove your videos
Thank you.
Looks like the modified 562 is approximately equal to a stock ms400.
These 562s are crazy. 105 of exhaust and power peak at 10k rpm. Man what are we talkin about🤷♂️
It would be absolutely the best thing u could do with that dyno of u could show how a different way of porting may or may not lead to different kinds of power development and curves and also how torque is affected.
Like doing a comparison between super high compression and super high exhaust roof/ max rpm so many way of thought and so many myths about these things
Great build Joe !! That’s great gains TQ and HP!! Your understanding of what it takes to make power is very impressive!!
What saw in all the 100’s of builds you’ve done holds the record for power to weight ratio?
Thank for another great video!!
Thank you!
I'm not sure what the absolute top is. But I would guess the 4910 is right close to the topm
Nice job Joe.
Have you done the field reset for the low and high? It really speeds up that re-learn process.
I just did a new short block on one a couple of weeks ago. Husky has made some changes to the seal/bearing by adding a nylon washer in there now.
The 90 seconds at medium load? I did notice some slight differences from the old case to the new. Hopefully the new one holds up better.
@@dynojoemods2764 yes that's for the high setting. Idle for 30 seconds when you start it for the Low. You will likely hear it cough and sputter when idling, then clean up.
How does it compare to a stock 572xp? I would like a 562xp with 572xp power
It is a bit less than a stock 572 from the 572s I've had on the dyno. But being such a light chassis it will feel great with the added power.
👍👍👍
Nice build Joe 👍🏻 Was that Hylomar Blue you’re using for the base seal? I’ve recently acquired some Hylomar aerograde but have yet to try it on a build - still working through a heap of Yamabond 4 that I bulk bought. I’m guessing you find it gives a decent seal otherwise you wouldn’t be using it, but do you find it significantly easier to clean off? That’s my biggest gripe with Yamabond - it’s a real pig to remove. Also I had to re listen to your numbers as I thought I’d calculated the blowdown incorrectly - 13 degrees is real short but that 562 clearly rips. I rarely go below 20 on a build. Why do you think they’ve gone so short on these newer gen saws?
Yes hylomar blue. I have been using it for a couple years now. Really like it. Cleans up pretty easy. The shorter bd is an emissions thing. Since these allow fresh air in it can help purge the muffler with air before the mix starts to enter the muffler.
It’s a cunning design for sure. I’ve yet to get my mitts on a 5 series saw - they’re not common here in Singapore, what with no EPA people tend to err towards older and cheaper designs like the 3 series Husqvarnas. Thanks for getting back to me, have a great day man 👍🏻
Short blowdown doesn’t just work on these saws. I’ve gone as low as 13 on a 365 throwaway cylinder with 105 exhaust and 76 intake and it runs strong. I’ve tried many different blowdown numbers and I much prefer under 20. It’s important to have 40 degrees from when the intake closes to when the uppers open.
How did the bottom end wear out?! Is it just hard use or neglect?!
Think it was a bit of both. Use and a failure.
I have about 5 years on mine and I would love to get it ported but should I start with a new one ?
Hey Joe, 620 vs 562? 😊
What do you charge for this work? PM me.

Im surprised that you would work on these. A problem waiting to happen.
It is a tough one, most new/modern saws are going to this style. The later model ones seem to hold up a bit better than the early run models. Not pushing crazy hard and a bit extra oil, they should hold up well.

Is this something to where We can send in the cylinder and the muffler and have done?
