I've already got several sets of jugs that won't work with standard pistons and rings and any of them can easily be bored out oversize, it's just funds and the odd hexagonal shape of the 'tuits that've come galumphing my way lately that keep that from happening.

I don't necessarily need the rods but this way I'll have something handy to throw at the cats if they sit on the bike and start to ventilate the new B and H Specialties seat cover like they did to the last one.

I'm almost done with the upstairs bathroom so I'll try to get some work done on the '79F head. I still think that'll be a hoot to run so it'll have to be ready pretty soon because there's a set of pistons, rods, rings and jugs on the way from andreashweiss that'll drop right in.

Wow, Scott! I knew that motor was a heavy smoker when you blew past us that time on the ride up to Bishop's Castle 'cause I could not only see some smoke, but I could really smell it.
But I can't believe those pistons! Oh man! Talk about raising your compression!

Bob, the really, truly bright side out of it all is that I finally found and eliminated that weird intermittent knocking rap that's been in the engine since I bought the bike, even after the rebuild five years ago: piston slap.
Except for the smoke and oil consumption, with the new(er) pistons and cylinders the engine's never run so quiet since I've owned it.It was just starting to make unhappy noises again when the spark plug went walkabout and I futzed the repair so I put the poor thing on a truck before it really hurt itself.

well if the piston and jugs were going to go for scrap
i will pay to have them shipped here and a nominal amount
that way when i have a bit of time i can play around and see
how much time it takes to sleeve and finish the 4 holes79 SFComment

Murray,
I think I may have misunderstood what you were saying! If you want the XJ11's 10M/3H5 assembly they're yours for shipping or even better I can send the '80G's 2H7/3H5 assembly from Columbo that already had a pretty good case of piston slap going on.
Oh, do you want/need the pistons and rings too, just the jugs or do you have something else in mind? If you've got the time and the technology and you're going to re-sleeve anyway you can clean up the pistons to a few hairs undersize, then bore and hone the sleeves to fit the pistons instead of praying the parts will be close enough to spec. that they won't just pretend to be happy while they aimlessly rattle around in their bores and hatching escape plans with their cohorts.

i would want the pistons and jugs together

He's Gone
I got a set of decent 2H7 jugs, pistons, rings, rods and bearings from Andreas Weiss. I've started cleaning stuff so I can put the engine back together and I've decided that I am not going to use 3H5 pistons with the 2H7 head. I don't trust the Intake valve-to-piston clearance.
When the engine's finished I'll have a 1980 Yamaha XS1100EFGL:
'78E jugs and pistons
'79F cylinder head
'80G engine case and transmission
'80LG crankshaft and connecting rods.
I'm going to pull the oil pan and rummage around for goodies and treats, then check the rod bearings so the engine may get the 'new' set of matched '78E rods along with the pistons and jugs.
This is the #1 3H5 piston. There is seriously thick and heavy carbon built up after less than two-thousand miles.
The carbon was sliced with a razor blade, then half of the piston was scraped clean and the depth of the remaining carbon was measured with a digital caliper.
The greatest depth of the carbon was in the Intake valve relief cut-out: 0.048 mm (0.019 in)
The least depth of the carbon across the piston crown was: 0.029 mm (0.001 in)
The rings didn't seat and the engine was slurping two quarts of oil every sixty to one-hundred miles but oddly enough, the gas mileage was excellent and ranged between thirty-five and forty-two miles per gallon.

You betcha!
Since the 'new' 2H7 jugs and rings are already broken in to each other I could put the 2H7 rings on the 3H5 pistons but that's a little too hokey and I see another teardown in the not-too-distant future if I try to get away with something like that.
Oh, well, it would have been fun.
