Tearing down my JMSSAWS, one by one...

This pic isn't as clear, but it's another one of Jason's

 

[huskihl]

it has been posted that he can't cut them true on a lath either, best to have it checked.

I agree.
What do you think about the vertical lines at the intake side of the upper transfers? There's normally a wear line at the edge of the skirt, but a 7900 piston skirt isn't that wide

 

[wcorey]

this is not normal

Looks like it was sanded with a drum or mandrel/flapper.
Why do this on an almost new cylinder?
Hmm...

 

[MustangMike]

I'd flush the case real well, make sure all the bearings seem OK, have someone check that the cylinder is true & OK, then just put it back together. I hope you got lucky, with no major damage.

Also Sondre, no need to feel foolish, some of the best & brightest on this site have stuff done by Jason. He pretty much had everyone fooled for a while.

Why wouldn't you trust a guy who sent his saws to the GTG for everyone to run???

Hope you got lucky with all of them.

it's a 7910, I haven't been into one so I can't comment on skirt width

There is something goin on with the cylinder wall, as Tree Monkey said... it's not normal

Both intake and exhaust side have this pattern.
Here's a pic from the intake:

Thanks Mike. I do feel like a schmuck, though. Lol

7910 had a slab sided piston. 7900 has windows. Same skirt width. I don't think they're much more than 60% of the width of the bore

Don't

Don't

Thanks Deets! He had me fooled for too long.

Here's a new oem 7910 piston and jug for comparison

The thing is... he can make a saw run pretty good.

He certainly can. Nothing wrong there.
The obvious shortcuts and blatant dishonesty is what has made me start taking them apart. If he's done shoddy work to many others' saws, there is no reason to believe he hasn't done it to mine.
Like I stated in my first post, I'll share everything. The good and the bad. I'm not out to make anything look better or worse than it really is.

Hopefully you don't run into many issues.

timesert it's done and ready to go

The best thing about the whole deal I've had with him, is that I've been so damn busy I've barely been able to run them at all. If most of them are salvageable, like this one probably is, I'll be fine. The saws definitely run. They may not be the fastest or strongest, but I'm ok with that as long as I enjoy them.

They don't have to be the fastest or strongest as long as they hold up
