A guy that tuned my friends bike with a power commander, told him that if you use a fuel pak with the new engines that shut down to one cylinder, they are bad for the bike and can burn up the cylinder. Have anybody on here heard of such a thing? His bike is a 2009 Street Glide SE big air sucker, true dual rineharts and he had cam work done. The reason why I ask is because I just bought a 2009 Street Glide with a fuel pak, Vance & Hines true duals and SE big air sucker. My friend is now telling me to disconnect the fuel pak or I am going to burn up my motor. Thanks in advance.
