Clacking sound ? was created by pete greek1
Is it just my carbs, or does anyone else get a clacking sound from their Mikuni R S 34 Flatslides at low speed ?

I have not installed my 34s yet, but I've heard them being called rattle slides before.

I have RS36's on my ELR clone and they do rattle, I like the sound. I guess the RS stands for "rattle slides."

Doing a vacuum sync may help with the noise, but not remove it. I also have the Rattle Slides, and at Idle it is way different than the stock carbs for noise. but they do run great, very tunable, parts pretty easy to get, Jets reasonable, etc. JetsRus has most everything and decent prices.

A really good carb synch will eliminate the majority of the rattle. The adjusters on those carbs are very touchy.

Thanks Larry, carbs were recently synched,, it's not loud or anything, ...it's just a sound I never heard with other carbs & wanted to know if it was normal, by the comments, I guess I've got nothing to worry about :) :) Pete
