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 Always ran 91 in it.
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..
i don't no how mutch alcohol there is !!
i do only traill riding and forestery road we make around 120 up to 200 miles on a week end so it is imposible for me to bring enough gas with me i have to run on pump gas !!!!!!!!!!
and yes it is wen it's in low rpm and i gun it the engin ping !
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.
