MMWS/CROSS PERFORMANCE MS661 TOP END

[RI Chevy]

Computer carbed though.

I am really surprised that these chainsaw companies haven't produced a "high performance" model that is factory ported to skip the after market port jobs. They have all missed the boat.

Could be down to the emissions regulations.....along with the noise Db count.

Automobile companies don't have any problems producing high performance versions. Corvette, Camaro, Mustang, Viper, etc

 

[mdavlee]

Just have to have enough EPA credits and pay the gas guzzler tax on those big HP cars.

There not a 2 stroke ..inherently bad for emissions .

The computer is how they are doing it as stated above. Take a ride in an evinrude e tec nasty sum *b-wordes. Two stroke with an attitude. Light weight throw you in the floor torque. No old two stroke can touch that.

 

[jakethesnake]

That be a boat motor for folk that don't play in the water

 

[RI Chevy]

I wonder when we will see 4 stroke chain saws. Be better for EPA Regilations. Outboard motors made the switch.

Tree service guys will be all over this, I'll definitely buy them, but I never have sent a saw to mastermind simply because I never know what job will come up and the thought of a saw leaving my side would cause me to loose sleep... I know stihl and husqvarna will be watching thisome!

That's why you buy 2 of them:

Yours is nice: but I won't own one.

All the screws would fall out as soon as I would take it out of the box, or the oiler would start pissing, or the cylinder would score on 32:1.

I hope you checked the fasteners after I touched yours: you know I'm snakebit.

It's all good so far. 2 bottles of loctite have got it together.

Maybe that's what I keep forgetting, and I certainly Knows.

This is the Cross jug Keith.

Timing numbers for the gearheads.

Ex 100
Tr 120
In 82

And the OEM jug.

Actually....no.

You know me J. I'm trying new numbers again.

The other one is at 102 on the exhaust, 126 on the secondaries, 122 on the mains, and 85 on the intake.

 

[Keith Gandy]

OK......you didn't read the thread. LOL

Lol! Actually I did! Short memory. So 120 ( flat ?) on Cross and 122 to 126 progressive on factory?

 

[beaglebriar]

Both saws run real good Randy. That's very impressive for an aftermarket cylinder.

Sitting at .030 squish there's still a small/easy gain to be had!
