New Hyway Cylinder Kit MS461

[Mastermind]

Here's the Hyway kit for the MS461. Another fine looking item.

The plating is sweet, as it the squish band and combustion chamber. The days of crappy aftermarket kits appears to be over.



Very good job on the bevels.

 

[Mastermind]

No funky square exhaust ports in these kits.



Nice arch to the roof.



Clean finish in the intake.

 

[Mastermind]

Piston seems to be of very good quality. Yeah, I am surprised that it's so good.







Two different types of clips. No excuse for bending a clip out of shape.



The rings seem to be top shelf.

 

[Mastermind]

Now, who has a 461 that needs a top end?

Me thinks I have a stock Oem jug if needed for comparison.

That's clean looking.

Band plated?

I'll be doing a 461 before long. I do a bunch of em.

That's clean looking.

Band plated?

Yes sir. Plated across the combustion chamber.

Yuk

You don't like em like that cause they are hard to cut with a mandrel. You gotta start using your lathe.

It seems you might be coming around to where I was, a year ago. The hyway kits are pretty nice. Some of the squish bands are a little loose even after base gasket delete. Also I have used several of the 200t Stihl kits about 9-10 months ago and the rings seem to loose compression after 50-60hrs of use. I literally did 3 of these in a row and identical builds. The all went from 150# to 120 after 3-4 weeks of use. Swapped the rings for cabers and the problem was solved on all three. Since then I just stick to ordering cabers with all hyways top ends. I have a giant box of hyway rings I won't ever use.

Randy, squish and timing numbers? Determination on numbers and if they are good to run out of the box?

I hate plating on the band. Takes about 3 minutes longer to cut them. I still don't like chucking them up in a lathe. I may play around with it more after I get the 2 last saws done. Just out of cylinders to play with now. I hate to try it on a good 66 jug.

Did the rings look like these?

I don't have a 461 here to check it on right now. I shipped two out last week. There will be another thru before long, I do a lot of those saws.

I've been wanting to do a video on setting up, and cutting squish. It would be a 15 minute long video though. Who's gonna watch a video that is that long?

 

[mdavlee]

You need to. It would be like Scott's video cutting it with a mandrel.

 

[Mastermind]

I need some video editing software.....and I need to know how to use it. lol

 

[Elim]

You get all the cool toys, Randy. Thanks for sharing them with us (again).

 

[Mastermind]

If someone has a 461 that needs a top end......they can get this cool toy.

I just did an ms 460 and used a new Hyway kit. I agree that the quality is much improved right down to the bevels and casting flash.
Piston and rings looked like good quality also. Removed base gasket and squish is right at .023 , Ported muffler and saw runs great. Also I have seen a few Hyway kits recently with meteor pistons on Ebay .
