This movie is about a desert motorcycle racer who somehow travels in time on his dirt bike during a baja race to the old west and is being pursued by thieves who want the "machine". He is helped by a woman in a small village. This is all I saw on TV and now want to see the rest of it. Any ideas on the title?
