As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

Carbs are running extremely rich at around 20MPG, makes my jacket stink like straight fuel.
Just finished top end rebuild now onto the carbs.
Currently in the middle of rebuilding the carbs with the help of a document pulled off this forum.
I also just ordered the Sync gauges off Amazon so should be here in two weeks.
Got the first carb disassembled with the main jet showing 1025

Will cleaning them and syncing them help that much with the mileage?
 
Yes, and tuning them properly. Make sure you read up that as well. Good to read you're doing your own mechanical work. You should be getting around 40mpg with that bike.

Closer to 50 if you're not racing it everywhere you go.

Yeah i should do some reading on that cause i am quite new to this lol
When you say tuning, the only things that i could see that were adjustable were the "pilot air screw", "pilot fuel screw"... also have another on the outside i am assuming if for the sync gauges.

Any recommendation on sources/procedures to help with this tuning
 
Tuning VM carbs is all described on Cliffs site, http://gsarchive.bwringer.com/ look under the VM rebuild which you probably already have and under 'plug chop idle mixture adjustments' and somewhere in there it describes how to adjust things with the highest rpm method.

A lot of that may be ignition related if you are still running points ignition and if you haven't maintained them lately.

Thanks,im gonna see about the carb tuning procedure after i get them cleaned and go from there....
 
Do the ignition too. They need routine adjustments every year or so, and it probably hasn't been done in 30 years.
