Carb needle question '83 GS1100ED

Joe, you have any back popping when closing the throttle at around 5K as its winding down??

Josh,

Very little. Certainly nothing loud like a backfire. You are probably more likely to have popping because you run more discs. The more free-flowing the exhaust is the more likely you are to have popping on decel.

Thanks,
Joe

I dunno how some of these guys do it then. I know that Bill runs wide open i think and doesnt pop. I dont want to bump the pilot, makes the bike idle and off idle slogged. Maybe i just live with it...

I use that extra DJ washer as a half notch tuning tool... in my experience it makes no difference to anything whether it is in there or not from a physical standpoint, just how it affects the mixture.

If you measure it you'll see it is a half not a whole notch (at least on my kits) because you're failing to take into account the thickness of the E clip (on mine it lines up with the bottom of the next notch not the top).

Run a 47.5 pilot jet with a 170 pilot air jet and that should cure all popping and low end woes and also lean that needle one half notch with an extra washer over the e-clip.
I bet that'll do ya!
