Hi all,
Quiet weekend with damp cool weather so pulled plugs on my 15 RGS w/ Stage 1 103HO. K&N AC vented to atmosphere, V&H True Duals w/ Rineharts. 19 k on these plugs, 37k on the bike. Running good with mileage 42mpg most of the time. Dynoed at 84hp /104 tq tuned with Harley Race tuner at Yellowstone HD.
Thoughts?.... thanks.... goldie

19k on plugs, 37k on motor

 

Color looks great, electrode warn. I'd replace them.

 

curious as to what's the gap on them now.

 

I did replace plugs and checked gap on used at .42 now. They were set to .40 when I installed end of Oct 17.....goldie
