Just an update!! I changed the oil with amsoil 60w synthetic and made a big run wed night, bike runs great, also the oil filter on the X-wedge, use the Twin-cam filter not the evo filter, told by s &s. You can use evo filter but they prefer the twin-cam filter. I think they said they used a twin-cam oil pump in this motor but don't quote me on that. Ride Hard!!!!!
