i am having trouble with plugs fouling at low to mid range despite fanging the crap out of it on full noise. Top end no problem. Have dropped the needle as far as it will go and am running a 175 main jet. Main jet has to be 175 or bike will and has seized. Any suggestions appreciated. I ride mostly at sea level but sometimes up to 1000m above sea level so air density shouldn´t be an issue.
