Mastermind Meets The MS500i

[MG porting]

If you ask me I think it wouldn't make sense to cut fuel off to limit the saw just seeing that being a really bad idea considering that's what lobs the bottom end.

I am not saying this is the case, but drowning it in fuel is still also an option for rev limiting.

Spark cut could be why it sounds fast/rich when limiting, but EFI spark cuts don’t always create such well repeating/consistent sound when in action.

Anyone got an oscilloscope? could answer these questions fairly easily.

If they cut fuel to limit the rpms would it not scream lean???
If they cut the ignition it would go rich thus causing the hard 4 stroking sound we hear???

What do you fellas think?

Maybe it’s way past my bedtime and my thinker ain’t quite clear. Idk.

Has the MDG been hooked up after more running.

Wondering what the maximum rpm achieved was after a good and proper piss rev?

How many BTUs?

Saws are with their new owners.

 

[Sawrain]

How many BTUs?

20500 would be great.

I think that could be a really good idea! Looking at my 562, I could easily drill a hole (maybe 3/8") angled out in that area.
Is that the flywheel rim I see through the vent? Or is it the coil?

Thinking of stihling the notion!

It is the edge of the flywheel.
