Inside the MS500i - Snellerized Style

Nice job.
I must admit. Not sure what kind of wood your cutting, but it looks like chain was dull. All I saw was dust flying. Might be better with a different test log. Just mentioning it. But saw sounded great.

Raise the exhaust and see how it likes it, leave the rest be for the moment

The cylinder is already off and the exhaust port laid out Another .030"-.035" is coming off the roof of the exhaust.

It feels amazing! I was shocked when I timed the cuts that it wasn't showing what I felt.

Was the chain good and sharp???..Or the wood just petrified? Looked like Aussie hardwood.

Is there room for more than 60 percent of the bore?

Will you be adding an "Almost" to the title of the 2nd vid?

Not unless you drop the bottom ring end locating pin into the exhaust port.

It was a brand new Stihl RS chain just a few cuts ago, but after closer inspection, I can see that it could use a little attention. This is dry Ash, so it's going to be dusty no matter what.

Ahh. Dry Ash. I cut some using Stihl square box chain. Chain was shot in no time. That explains it. Some hard wood for sure.

It seriously liked raising the exhaust. It's now at 102°-102.5°. I didn't touch anything else. This thing seriously came alive. It gained a lot of RPMs and didn't loose a hint of torque! I am very pleased with it at this point. Now to get it out and run it with the two 462s I still have here, along with my 440/460 hybrid, and maybe @LowVolt 's ported 461. Might as well throw the 390XP in there.

As you can see, I'm into a knot as well

Nobody likes a dry ash!

 

[RI Chevy]

Nice sir!!!
Very nice gains there.

I'm not inclined to raise the transfers. I'm afraid I would loose some torque and it's not worth it. I'm happy with it at this point.

It's amazing what only 2°-3° of port timing can do!

That's a bummer, but it is what it is.

 

[mettee]

It sounds pretty pissed off the way you got it.

 

[MG porting]

Here's some of the final port work.

OK, I'm probably going to catch some flack for this ugly grinding, but oh well. It's the inside of the muffler and I'm not sure how you'd make it pretty anyway. I suppose bead blasting would help, but I don't have a sand blaster. Fire away! Lol

I pitch my tent in the "Just let it flow" camp. I am not of the opinion that there is any performance tuning to these muffler. I believe it's all for sound and decibel control. I simply want it to exit the saw as fast and easily as possible. I could be wrong, but that's how I do it.

​

Looks good enough hope it runs stronger.

It's just spooky how you guys can have a saw torn, very highly modded, and back together 3 times in the same amount of time it would take me to pull off the top cover and maybe, possibly, get the air filter off and the spark plug out...
