You’re on a whole different level brother.. seriously this is incredible stuff.

Nice bit of exhaust back pressure on that muffler I'd expect. Nice clean design.

Joe great work as usual, I like the incremental changes that are now observable because of all the work you've done. Bravo! my friend Bravo.

Dyno Joe, what you do to these saws is impressive. Always very very interesting. And your work is nice and clean too. Great stuff

[CharlesBrisco]

Cool build great vid I hope you can get a plater all lined up

[kalybnielsen]

This is awesome. Good plan with the sleeve, can't say anything negative about it, I use Stihl rings when I rebuild TriZingers with big bore kits, never had an issue

The future of ported saws, get your sleeve on!

May take a bit longer for that chrome ring to seat in as well. But boy when it does, that thing is gonna really wake up! Excellent work.

Your sleeve work is looking real nice! It is a real bummer about the plating. Looking forward to feedback on this build. Hopefully you can come up with a plater to work with. I suspect you will be able to do a fair amount of these big bores. Thanks for sharing!

Makes me want to do a porting job……. I love my stock 500i, but what does a porting job involve. Those are HUGE gains.
