I just bought a '00 426 with a locked up motor. I put a new top and bottom end, new head, valves, valve seals, cams and timing chain. Everything is new. Now the bike starts and runs great, but oil will not register on the dipstick. I measure with my ratio rite cup exactly 1.75 quarts with a new filter and there is no oil on the dipstick. I even put 3 quarts of oil in the bike just to see if it would register and nothing. FYI...The bike will not start with 3 quarts of oil. I can run the bike arround the yard for 10 min and shut it off...let it sit for 5 min and there is nothing on the dipstick. I am stuck. Has anyone ever heard of this?
