Yo mon Julien, bienvenue sur le forum :) (Jul is an old RL friend of mine, almost family!)

Mine has been pinging ever since I went with my first HC piston... Never bothered with it and still running strong. Danny told me it didn't ping when he ran it on the dyno though but whenever I shortshift 4th or 5th and lug it makes a pretty loud ping... I just shift higher to compensate :p Always ran 91 in it.

When "pinking" just rub till moist then ride it hard! Install a longer stroke if needed.

What kind of octane booster?
There's pump 94 in some stations in our area so no booster in play, just higher-than-normal-octane pump gas.

How about gearing? Do you lug the motor down low and it pings or is it at WOT.. Im thinking that you are lugging it down to low in the RPM's..

Not alcohol compatible.. So how much alcohol is in the 94 that you are using.. most fuel has 15/20% now and I use 93 to lean out my shell 110 ie 2gls of 110 and 3gls of 93 with 15% alcohol.. This is what works for me..

Quit lugging it and go plug DL told you about, they can be found at the kawi dealers. Just raise your shift points a bit and you'll be good i almost bt the farm on it.
