Carb Slide Question
Hey everyone,
After a carb cleaning i started hearing my carb slides chatter at idle when the engine is at operating temp. If i give it a little gas it goes away for a minute then starts again. Is this something i should be worried about? Does it indicate something in there is failing i.e. the diaphragms? im going to tear into the carbs this weekend to tune them and just need to know if i should order some new slides. Thanks All |
It's pretty common, so nothing to worry about. ;)

thanks hawk

Is this a loud tapping that comes and goes at idle, that i tbought was loose cam chain from worn cct's.
Can carbs rattle/tap pretty loud? Sounds like a lifter tap noise from old v8. |
I get the carb chatters now too but it's not louder than any of the other usual noises. If it doesn't hurt anything then I'm not going to worry.

The slide noise sounds more like plastic on metal ( i guess cuz it is )
After following 8541HAWK's carb set up i dont get the noise anymore and it feels like a new bike. Im a little rich on the bottom end so im gona mess with them again this weekend. Carb set up |

Carb slides
Did you pull the carburetor slides off the throttle cables on this lastcleaning / rebuild? If so you may have accidentally mixed up the slides placing slide #1 into carburetor#2 and slide #2 into carburetor #1. Carburetors due wear down over time from the violent amounts of air gettingpulled through them and the two carbs will wear differently and develop theirown patterns of wear to the point that one of the slides is loose in theunmatched set. If you can live with the rattle the only hazard I can see from a situationlike this would be one of the slides sticking open when you back off thethrottle. JMO / SIRR1 |

One reason is by plugging a lift hole, you have slowed the slide down so it is not slamming shut as hard.....at least on the front ;)

JMO / SIRR1 I only do one carb at a time so not to mix things up;) |

JMO / SIRR1 Throttle cables just go to the butterflies. It causes no issues and happens even on new carbs and\or slides. It is just a SH noise....;) |
