Unbalanced Carbs

Discussion in 'Technical and Troubleshooting Torque' started by aimre, Feb 5, 2008.

  1. How do i tell if they are? Without using a mnonomononmeter?

    Like are there any tell tale signs?

  2. funny idle, but that can be caused by a number of things.
    also comparing sparkplugs....but again, they are influenced by a number of things.
    the best way is to use the vacuum guage thingy's :)
  3. Fnuuy idle is a good way to tell, anotehr good way is an engine that farts and grumbles transitioning from idle to cruise revs under load. It'll surge and generaly not run nicely.
    I have had what I thought were well sorted carbs on a bike beofre, balanced them and been amazed at the difference.
    I think a good tune and carb balance should be number one priority for any used bike (and some new! :shock: ) that anyne buys. It makes teh bike so much nicer to ride.

  4. I think you meant a manometer. ;-)

    Uneven pressure from the pipes (won't work if a 2 or 3 or 4 into 1 is fitted).

    Uneven sound - it's hard to describe.

    Out-of-sync carbs are not a really big issue on a twin, can be more annoying on a four. Dirty fuel or wrong valve clearances leading to burnt valves are much more serious. Carb sync is a "finesse" thing about bike tune, more like dotting your "t"s and crossing your "i"s when you write.

    What is the problem you are experiencing?

    All the best
