As I only have gaskets and no new pistons (yet), I may have to go back to a 2-valve engine that has already been machined and ready to put together.

After cleaning with heavy duty penetrating oil and brake cleaner.
Cylinder with the rusty exhaust port...
No way this would have just ran itself out. Honing, is NOT even an option. It will have to be bored.
The other 2...
So much for just installing it and hoping for the best.
The exhaust was hooked up when I found this bike. Don't assume that it is good to go.

You done good, pilgrim.
Many's the child that would've run it if it started...then bitched about oil consumption and low power. You're going about it the right way. So it takes a little longer...?

The engine turned over real well by hand with compression.
I just didn't like the looks of that port.
At the very least, I was going to port and polish it, replace valve stem seals, etc.
It has been sitting with solvent in my parts washer and has been holding solvent for about 4 hours so far...
The worst cylinder, #4 on the left, is not in the worst shape.
#1, on the right, is empty!
After a little light scrubbing with a scotch brite pad, they don't look too terrible.
What I find most curious is the markings. This is an '83 cylinder head and obviously, this must be from a machine shop!

Thanks for any and all opinions.

The other two just don't look right imo.
Awesome progress. That's a years worth for me

Nah, it's no machine shop markings. Suzuki was making 16 valve heads way back in 1907. They just hid them in a storage room for 75 odd years.
Sorry about your less than happy discovery. I'm not super familiar with the parts search for these engines yet, but possibly a good block and stock sized pistons could show up on ebay. That plus a little service to the head would get you back in business. I know that this happens a lot on the Kaw motors when someone decides to go with a big block motor. They will sell off their jugs and pistons together in usable condition. Often times they can be had for less than $200. Just an idea.

Got to do a little work today.
Pulled one of my '79 1000L engines out of hiding and it was time to see what condition this one might be in.
When I bought this bike, it was showing 68,657 miles.
Before I cleaned it up a few times...
When I started to disassemble it, I was met with a very pleasant surprise as the PO had replaced the factory points ignition with a Dyna-S electronic conversion.
Which costs about what I paid for the bike! :thumbsup:
The top end was in pretty good condition.
The pistons only showed normal condition for an engine with only 20,000 miles on it.
Another pleasant surprise! It has .5 mm over-bored pistons. Showing that it had been rebuilt at some point.
The piston with the worst scoring, was minimal.
Combustion chambers were in pretty good shape as well except for a bit of rust.
At least I will be able to use the pistons, cylinder and cylinder head on another engine in the future. As well as the carburetors. (Way too small for my build.)
That's all for today.

Getting the 1276cc 11.5:1 pistons/sleeves/cylinder ready to replace the 997's in the '79 2 valve block...
If I can't have the 1100 4 valve engine running right away,
might as well make a killer 2 valve engine!

So what octane fuel do you plan on running? Do they still make "Turbo Blue"?

As long as he stays close to home (5000 ft) or above in the mountains nearby, he'll do fine on the 100 octain available at the VP station. The 1 and only VP station within 150 mi. He'll just be doing loop rides out of Reno. I can't see him riding that Beastie very far anyway.

Or, stop by any Airport, Summit Racing, Etc.
Actually, I will be milling the pistons to about 11.2:1 Compression ratio so that it will run happily on about 95 octane.
My 10.70:1 runs fine on 92 octane.

Alot can be done with timing to help as well, just wanted to make sure you thought about the needs for that high of a compression ratio. Around here, since they closed the Dragway, I would have to buy something like 104 Booster.

Sorry for the delay.
Change in plans or back to the original plan really.
Got the cylinder head close to ready...
28.5 intakes and 24 exhaust...

After being side tracked with the 1200G, '63 Pan head, '79 GS1000E from junk and the CB 750F projects, it was time to spend a little time on this one!
Apparently, the '82 GK triple tree lowers don't like the '79 frame!
I had to remove that section from the steering head.
Perhaps tomorrow I will find some more time for it.

I dunno if the '82 did or not, but I'm pretty sure the later GKs used a 40mm fork leg. Which would probably change the trees up a bit. Nothing you can't overcome though.
