Well it runs. Still about the same. The left side is not running as hot as the right (when sitting on the bike)

Re: carb problems
No............the left just runs colder than the right....and the jet needles have to be handled differently...as I well know..........after all these years of preaching .........and a 142.5 will just wash the whole thing out fast with those log needles provided by the epa......lots of fuel on the high end (142.5) and about none where you are at most of the time.............

Don't know how much truth there is in this statement. Seems like any engine shouldn't run hotter on one side than the other period. But I am new to these engines. Far different than all my Honda CB builds.
It looks as though I have the BS34 Mikuni carbs.
When the engine revs to about 3K in runs smooth, when it goes back down to 1200 rpms it shakes like crazy. Thought it may be a sync issue. I got the vacuum gauges out and was going to do it but i don't see a screw to adjust it. I know the tubes on the intakes is where to place the vacuum gauge bit can someone direct me in how to sync them? I read about a spark plug cap being removed allowing the engine to only work off one cylinder and doing it that way but it seems bizarre. Wanted to double check before I dove in.
Thanks again for all the help.
