Carb pro needed

Post by Swamp donkey » Mon Sep 23, 2013 3:45 pm

I just rebuilt the carbs on a 83 gl1100 interstate. After reading some info about the carbs I realized that I didn't keep the vacuum chambers with each carb they came out of...big mix up. There is no vacuum on carb 3 either, also when the engine is rev 'ed up it falls back to slow if anyone can help I would sure appreciate it. Also this site is the bomb.. Never seen so much info

Mixing the vacuum slides can cause problems...One might be hanging up...Even if it's back in the same place
I usually test each one before I put them back on the bike(shop vac test).
It just might be quicker to remove the carbs and test each one then set the throttle plates than to try to fix it on the bike...
You can try each slide in a cap in turn to find which one fits best then polish them till they slide smooth.
Those slides absolutely must move butter smooth from bottom to top with no scraping or binding..Even rotating the top cap can affect it....been there seen that.
Also the rpm drop....My 1100 didn't die off super fast either.

Slow RPM drop can be caused by tight valves, or unsync'd carbies. Have a look.
