No. I gave up on the Wiseco piston. Even after multiple cleanups, it kept scuffing. This saw has a Meteor piston. I pulled the muffler cover last night and it still looked brand new.

Wiseco pistons HAVE to be brought up to operating temps before putting a load on them. Could that have been the problem?

They had a rep for cold seizing back when 2 strokes ruled the MX world.

It's April 2nd now;)

Here's a 066 I just ported. It has a freshly honed cylinder, new piston, and new crank bearings, so there's a lot of break-in yet to happen. Still seems to be quite strong. It's pulling an 8-pin rim a 28" Stihl RSC chain.

You might notice there's no chip guard on the saw. You can really see how much they direct the chips downward. I just slapped this spare cover on there to keep the one for this saw clean. It's going to a new owner soon.

:jawdrop:

Wow. I obviously haven't run it, but that is one strong saw. :clap:

That'll make one hell of a milling saw. :greenchainsaw:


Nice work (again) Brad! :) :cheers:

Wow, when I had my 7900 ported I was told by someone that it was going to overheat and cause problems, becasue the stock cooling wasn't going to be able to keep up, I would have to say this would be true for a ported saw missing a couple decent sized fins farthest away from the flywhwheel side. Hmmmm maybe my 7900 will be able to run cool, this gives me confidence and hope now...LOL:cheers:

I cut timber for two years with a 288 that was missing all of the cooling fins on the PTO side and I never had a problem with that saw. It had about 1400 hours on that cylinder and still ran strong when I gave it a firewood cutter.

Brad don't worry about overheat, two corners missing aint no thing. If I posted a pic of a 371 cylinder I have here, that has been in service for a year in a landscape company, it would put all the nay sayers to rest! This time around its getting ported more and pop up time.

My grandma had more run time behind a saw that most of the guys that make knee-jerk comments about factors relating to saw performance and longevity. And grandma was tougher than most of them too.

Ha ha ha. tough ol Granny EH!!! That's awesome.

Yeah, she was one-half of a mom & pop logging operation here from 1939 to 1966, only taking breaks for WW2 and Korea. One of her earliest jobs was rigging oxen and horses for skidding logs by hand. Later, she set chokers behind a TD-18 when they could finally afford one. Of course they used the real chokers back then, 5/8" and 1".

Wow man, that's amazing. I bet those chokers were heavy!

The rigging and wood were heavy, and the people were light and tough back then. :)

I've got a real good story about those same grandparents. They bought a cafe/saloon after they retired from logging and one day a member of the local chapter of the Hell's Angels tried to ride his bike in through the front door. My grandpa chased him out there and off the property with a tire iron and a 30-06.
