I purchased a set of Cobra Pipes and Dyna Jet Kit for this bike. After installing the mufflers myself the dealer said drive it over and they would install the jet kit, this took (3) days! After receiving the bike, I drove it home only to find out the spark plugs were black as coal, the dealer has tried to say I did something when I drove it home. It's back in the shop, only thru pleading with their head mechanic to fix the problem. Has anyone else had this kind of crap go on?
