Mastermind Meets The MS660

[Mastermind]

I had a stock 064 and 650 the 064 ran stronger. Ported??

I'm gonna say the 064 would carry a long bar better.....even after port work on both.

The exhaust and the intake both have a shorter duration....

Does the shorter duration help keep the torque in the proper range?

I've got a yamadog wr426 that I'm too chickenshit to drive anymore. I can picture one of them scooters widened with some atv tires on it.....at about 60hp

Are the numbers on the 064 jugs consistent throughout production?

Too much duration raises the powerband higher than is realistic. In other words, loading the saw pulls it down and out of it. With a shorter bar.......not so much.

Better than the 066......but not completely.

I am learning the art of porting and see this slot cut bypassing the factory transfers on a lot of Pro jobs.

For educational purpose, why bypass the transfers like that?

I see it points to the intake side so I assume it is to help push more burnt charge out and give a better clean fresh charge for the next bang?

I like to think it adds direction to the flow. And maybe a little extra volume.

The saws I've ported seem to like em, so I'll keep grindin them in

Someone got a MS650 off the FedEx truck.........

Oh hell yeah. Complete with Christmas wrapping.

Although the bore scope was missing out of its package. Lol
Took me a while to remember where I put the dogs.

Strapped on a 28 inch bar

I fired it up in the shop. Man it sounds good
Gonna piss the neighbors off tomorrow. I'll get a video in a dry 22 inch red fir

 

[Mastermind]

We saved Christmas wrapping stuff just for you. lol

Hey randy I'm putting an 064 back together with new bearing do you put anything on the case gasket like motoseal

 

[Ladrhog]

I figured, that was a great Christmas gift thanks again.

 

[jmssaws]

The last few cases I did I used derco with no gasket.

518 with gasket works great

I don't have 518. I have motoseal. It's what I use on a base gasket delete

 

[Glock37]

Its a *b-word if you have to split case again
