Finally Heard It Run

Only changes between "79 and "80 are cosmetic.

Good to know my service manual is good for my bike.
I plan to check compression and clean the carbs tomorrow. Hopefully i won't have to pull the valve covers off. There's snow on the ground here and i have to work on the bike in it. So the easier the fix the better. Im tired of the cold lol.

First off you said it has pods on it, so yes it most likely IS running lean...too lean to idle.
Second you are having to run it choked to get it to idle, which richens it up and is then causeing it to run too rich.

Cure both problems the easy way by puting a stock airbox back on it or....
the hard way by getting a dyno jet kit and spending LOTS of time playing with the jetting and tuning till you get it to resemble a normal running bike.

I just got the carb to box boots today in the mail. Actually got them from a member here.
Im a little busy rebuilding the front end on my truck right now but ill get the airbox back in asap. Thanks for all the advice. Ill update when i get it back right.

So i got the airbox in and its still poppin out carb 1&2. Do you guys think it might be the valves?

What's your valve clearence.?

I haven't had a chance to pull the covers but that's not a very hard job to do is it?

Perhaps insufficient clearance.

Good Fortune!

Well i took my carbs apart in the break room at work (don't tell the boss lol) and who woulda thought my pilot jets on 1&2 were completely clogged. I guess when i cleaned them the first time i had too many cold ones in my system and completely over looked that little part.
I still need to get the tank cleaned out and check valve clearance but hopefully the carbs are good now. Im hoping that ill have some new intake boots in the mail when i get off work too. That would be nice.

I must have really had too many cold ones last time i messed with the bike. I was sitting on it checking the drag bars for fit and noticed i had 1&2 wires mixed up. No wonder it was running on one side and not the other.
With clogged pilots and wires mixed up its amazing it even ran lol.

I've got the bike running pretty good now just a couple more problems.
The problem is that now i have fuel blowing out the exhaust on the right side. Im assuming that its coming from number 3 because i left the petcock on prime and it was the only one that leaked. I checked spark on it and i have good spark on all cylinders.
How does the fuel go all the way to the exhaust without being burnt with good spark? Could it just be that the float levels are too high?

Would suspect at least one carb is flooding -- perhaps due to a leaking float valve -- and furnishing excessive fuel mixture or raw gasoline into a combustion chamber which excessive fuel is exiting through the exhaust.

At least some, if not all, of the excessive fuel isn't being combusted.

In my experience, partial combustion may result in black exhaust smoke and gasoline odor from the exhaust. However, raw fuel blowing from the exhaust may more likely result from no combustion in one of the cylinders.

Could spray water mist onto the exhaust headers shortly after starting a cold engine, and see which cylinders are combusting (water spray instantly vaporizes and sizzles off an exhaust header from a combusting cylinder).

Good Fortune!
