What Are the Symptoms of Carb Inbalance?

rmak · Oct 6, 2007

I've done the usual engine upgrades, mufflers, pods, re-jet and while the bike runs a lot better, it has developed some quirks: uneven idle to the point of almost dying occasionally and, when hot, takes a little more time to start. I've never balanced the carbs and I'm wondering if this is what I need to do next.

Are there any other improvement I could expect from balancing?

Thanks,
Rich

It will mainly improve the conditions you stated. It will smooth out the idle, but not 100% sure that it will totally fix the hard start deal. Would give it a quick balance and see the effects, its well worth the 15-20 minutes.

Recheck your jetting.. sounds rich. Try the mix screw first. If no go between 1 - 3 turns, change the pilots. Sync issues will sound like one cylinder running longer than the other if you slightly open the throttle, as a base point.

you'll know if your carbs are out of balance by the time it takes the motor to wind down to idle either with the clutch in or just sitting in your driveway in neutral.

If the motor wants to "hang" instead of coming right back to idle odd's are good your out of balance.
