Do you know what my compression numbers SHOULD be?

Here is a link to the thread he created if you want to comment directly onto his: http://www.xs400.com/threads/rh-cylinder-is-too-rich.19904/

A message from my Dad who has been doing the work in Michigan while I am in Tennessee: "Hi All, I'm new to the "forum world". Forgive me is as I learn the process. So I'm working on a 79 XS 400. The LH cylinder had a real bad plug cross headed. I removed cover and inserted helicoils in both...

I don't know what other details I can give. I clearly don't know what is going on.....

Or NOTHING changed. It is still acting the same way. It will run, but not well. The original post is still exactly what it is doing.

Everything is reassembled and timing and points have been set. Carbs are on a synched..... Still not running. I don't know what else to do. I'm at a loss. Any way this could be electrical in anyway? PLEASE HELP

UPDATE: My dad and I were able to tap both plugs on the head with a tapered tap. The tapered tap made the hole for the plugs larger, but came with adapters that had biting threads so the plugs fit great! exactly as they should. Next we lapped the valve seats because they had been leaking...

Finally had a chance to get into the engine. I found that the threads where my spark plug goes into the head was really stripped which didn't allow my plug to go all the way into the head. Because of this, I found that I was only running one cylinder consistently. Does anyone know what size the...

All the parts in my carbs are stock. Again, I have changed the carbs out with all new stuff and have the same problem, so I really don't think this is a carb problem. Needles aren't broken. I think they are set to somewhere around 2 turns out right now. That's what they had always been on even...

Your butterfly position changed once your bike was warm? Even by adjusting the idle screw while the bike is running (which adjusts the butterflies without taking the carbs apart) I can't fix the problem.

Yes as far as I can tell. I even recently trimmed up a gasket on the bowl because there was a chance that it could rub on it.

The crank case hose is attached. This is a pic of when I bought the bike and was doing some work so it may have been off at the time. I know they aren't the stock pipes. They were what were on when I purchased the bike. They are the factory plug caps and the spark plugs are whatever the manual...

What kind of pics are you looking for?
