064 I ported today and the 661 with a little different transfers.

Nice Jason. What chain and pin are you running?
How does the mtronic respond to the different rim pins?

Square filed Oregon 3/8 8pin
Mtronic don't mind what sprocket it's running.

Cool.

That 661 is bad ass! Sounds good too.

 

[jmssaws]

The husky's looked lonely in the corner so I had a 395 394 piss rev battle.
Here you go husky lovers,Shaun's 395 and trooney's 394 I ported.

Whatcha think about between cuts? Is it, Damn she's badass!
Does the M-Tronic seem to have plenty of fuel flow for all the added fuel need?
Also have you hooked it up to the STIHL MDG to see how far up the fuel table it's at. Air should it be where a stock saw sits? Timing is also changing depending on rpm.

only the piss revs? I have one of your mean stihls and it is great. You build a great saw Jason. Why are you singling these out? Do they preform better with less work?

Ok I reread my post and I hope you don't take it as offensive. I wasn't meaning it that way.

Definitely not less work,I have 8 to 10 hours in the cylinder on the 394.
I'm sure Shaun has some time in the 395 also. As I've said before, I've had several 394 and 395's and like them a lot.
Like how they run and feel.

It's probably because the 394 is a dual like a 066 but I absolutely can make a 394 stronger than a 395,not the 395 in the video,Shaun ported it and there very close,I haven't got a 395 to run that good.

There's videos of both these saws in this thread.

I'm listening for lean or fat,yes I know it's mtronic but old habits die hard.

In 2 weeks I've changed the cylinder 5 or 6 times,changed the muffler at least that many and have had bars from 16" to 50"
On it and not once has it acted up,runs great and is tuned good enough all the time.

I've had a standard carb on it 3 times and the mtronic is stronger by a good bit.
I really enjoy not having to chase a tune all over.

I'm sorry Jason I didn't mean it the way it sounded. I have watched all the videos before you have even posted them and you are making great gains of all of them. I didn't mean it to sound like that at all. I'm going to shut up now and reread everything in the morning before I post again.

I didn't take it that way,never even thought it.
I would like to port more big husky's but I seem to stay busy just porting 064 and 066's. I keep thinking there can't possibly be anymore 064 left but they keep coming. A saw is a saw for the most part, if you can make one strong you can make another.
I love porting a 394,they turn very nasty and that's something a quad lacks.

Jason goes above and beyond for testing and to make sure he gets everything he can out of the saws that he builds. He is a great guy and a great builder.

Do you do a reset on the
M tronic after you do a change?

 

[jmssaws]

No.
I'm a believer that the reset is a lot of the problems people have with the mtronic saws. Idles funny? Do a reset. Took 1 extra pull to start? Do a reset. How can a saw learn it's operator and elevation and the other 100 things it can help to make your saw run better if it's constantly wiped clean.

How many times have you heard,boy after 15 or 20 tanks my 661 really came to life,really takes a while to break one in.

It's not breaking in its learning and adjusting to how you run a saw,I say a reset is a last resort.

 

[RI Chevy]

He may mean the calibration process not a factory reset.

What's the difference?

Never hooked a ported one up but did hook up a 201tcm after opening the muffler and advancing the timing...the fuel values didn't change at all. Still like to hook up a before and after ported saw.

What's the difference?

Nothing.
