Hello!
My stock (except for K&N airfilter) 82 has always ran like a champ. Pulls clean to redline, idles smooth, and is all around great to ride. She has always done a bit of pinging when lugging (2500 k rpm) and really hot out (both engine and air temps)(easily controlled by a simple downshift), but lately it seems to be more than before. Even when using Sunoco 93 the pinging seems to be more than before.
I have checked the timing (static) over the years, and it has always been spot on. I am contemplating retarding the timing a "smidge". Just move the plate a "tad" (like those technical terms?) clockwise.
Any input would be appreciated!
Thanks, Steve

Re: Ignition Timing
Hello!
Still looking for some input on if retarding the timing a little will help reduce pinging, or should I be looking at other options?
Thanks!

Re: Ignition Timing
Between the oldham couplers wearing, oldham coupler slots in the cams being off center and the cam chain stretch, don't be afraid to retard the timing a bit.
Where does the ignition get it's drive from?
Where do the pistons get their drive from?
The cams are getting their drive from a stretched long assed chain connected to a sloppy two piece cam.
So the vales are lagging behind while the rest of the engine is basically staying the same.
