Well it runs..... but. After getting the oil pump to finally prime I turned my attention elsewhere. I noticed the left cylinder was sputtering and mostly not firing. Checked the timing, dried out the plug and ran it with the plug out. Good white spark. Put it in and tried it out. Seems to foul up under 2k RPM. At first I ran on 50:1. Once the pump was primed I threw another 4 liters of unmixed in.
So one would think perhaps I just need to get that carb sorted out. Here is the scary part. The oil ozzing out of right and center is black. Left is coming out silver. Just piston material from all the extra gas? Crank bearing spinning in there?.....
I did not use loctite on the bearings because I read some people believe it can cause more problems than it solves. What do you all think?

I'll see about a pic tomorrow. Its a lot of silver though. I did my best to get the rings in the right spots. Not sure, if a ring were up on a pin it would be pretty awkward to get it into the bore wouldn't it? Short of using force? I took a quick look into the exhaust port at the time and things looked ok. I'll take another look from both sides tomorrow I guess. Or pull the jug.

Compression is 130. Not great but.... I remember the last jug I put on I was tired and the center jug was getting in my way. But pretty sure that was the right side jug.

mahhh...when i'm not sure, i pull it off and do it again...yes, if wrong, a bit of force...not as much as you thing though... silver goo can also be the big end bearing going, sorry to say but ...did you did check end play?
or, if you are lucky...just a ton of shit sitting in your pipe.
get pics up when you can...don't run it again until we/I see it.

Crank was a rebuild by Don Pezzuto. I put NOS small end bearings in. But re-used the rings, c clips. We will have a look with fresh eyes tomorrow.

If the rings weren't lined up on the locating dowels, I doubt you'd get the cylinder on without breaking a ring. If it's "making metal" then it needs to come apart.
Just as a side note, it's good practice to NEVER re-use C Clips. Not suggesting that's the issue here. But those little buggers can cause such damage.
It's sickening to have troubles after a rebuild, but I'm looking forward to seeing what the issue is!

I actually took apart an h2 years ago where the c clip had either fallen out or never have been installed. It had so many miles on the that the pin actually left a pin sized groove in the cylinder wall. Maybe 1/16 inch deep!!!

After sleeping on it, yup at least that one jug has to come off. Its not going to clear up on its own is it. Hopefully I just messed up something at the top. If its down in the case this bike might just get drained of its bodily fluids and put on display in the living room. I have some audio recordings of it in healthier times. I can just sit and sip whine and listen to those sweet sounds and admire it fine Asian looks. Kinda like a message parlour with out the help with the happy ending.

Well the silver goo was hard to find this morning. I wiped most of it of yesterday. I have a couple of pics but, looks like I have to go find my photobucket account. I have not been there in years...

Well.  This cylinder is running rich obviously. I have the floats set to spec but thats about it so far. Other than that you can still see a little metalic on there. |

Found some oil in the pipe.  Looks pretty black today, but yesterday very silver.  |

That cylinder is barely running at all. Seems to be two issues.
1. That cylinder is not firing.
2. Metal particles in the spooge.
Is the reason it's not firing related to the metal particles? Get that pot off!
This may sound obvious, but is the ignition system, plug, coil etc beyond suspicion?
