I was having a little pinging on my 99' R1100R...had to replace my hall sensor as it had given up the ghost... decided to retard the timing slightly to see if it made a difference...sure enough, pinging stopped, but the bike had less snap and felt like it had a giant flat spot...so a few weeks ago, I decided to advance the timing slightly to get that snap/response back. I'm running 93 octane, an Axfied unit and larger R1200R injectors...f.y.i...
With a little advanced timing the bike has come back to life...I noticed the pinging is back, but not as bad as previously. Only hear it in 4 or 5'th gear when I roll on the throttle hard at speed. Out of frustration, pulled the plugs(autolite 9223)and put a camera down the plug holes to take a look...carbon on both piston crowns... doesn't look bad, but both are covered.
In looking at the plugs, right side was a bit ashy/white while the left side was clean and had a slight tan ring around the insulator...
The gap was set to .031, upon doing some digging, I've read opening up the gap might help the situation with pinging...opened the gap to .035 and sure enough, pinging stopped...I've also read that opening the gap up to .040 can be beneficial to the way the bike runs...any thoughts or experience with larger gaps?
Now I have to figure out how to remove the carbon...
