About two weeks ago I installed the power commander V, Rinehart slip ons and a new Air Cleaner on my 09 ultra. All parts ordered from Fuel Moto. My results were outstanding so a friend with an 08 ultra ordered the same pacakge. Yesterday evening we installed everything and then did the service and put in the mobil 1 v-twin in the engine, Spectro GL-5 in the trans and primary + in the primary. My friend took it out for a ride and was tickled with the new pipes, power and noted good difference in the shifting. Fuel Moto seems to put out a quality product. High recommend Fuel Moto !!!! The oil info was learned from reading this site. GREAT SITE !!!!!!!
