Hi!
When I bought my Bullet last fall, it just had a piece of hose running over to the chain. I left puddles of oil everywhere I parked and the chrome wheel was almost black with oil, wheel, tire, fender covered. I got that kit to recirculate the oil back into the crankcase and it works great. Now I can keep everything clean and the oil where it belongs.
Of course, right now its 26 degrees F and I'm indoors. yuck.
