I'm having a problem with the rear friction shifting on my road bike. It's easy to shift into a smaller cog, but the problem occurs when I shift into a larger cog. No matter how slowly I pull the right shifter down, I need to let cable out after I hear the shift occur in order to silence the chain.
I have a Suntour ARX derailleur, Suntour Symmetric shifters, a new SRAM PC48 chain and a new Suntour 14-28 six-speed freewheel. Any ideas or help would be appreciated.

Pre-index Suntour shifters work this way, this is well documented. I believe it was by design.
In fact, index Suntour shifters work this way - the indexing lever is designed to require a bit of overshift before the lever clicks - then as you let go, the lever moves back a bit. I have a bunch of suntour indexed stuff.
Back in the day, one developed the overshift/back-off technique; it's not hard to do.
