SPRING CLEANING ,1977 Yamaha RD400 FITTED WITH  TZ350 WATEROOLED ENGINE BACK IN 1979 One owner from new ,owner was a Tz250-350 Ama camel racer back in the 1970-early 80's The engine was professional fitted during the off season at Yamaha race team as a favor. It was barely ridden for 2years then mothballed in a garage from the early 80's till today .This is not for the faint hearted or some hipster or I need to ask the wife first or do i need to mix the OIL? The bike will need to be recommissioned since its been 40yrs .I have  15-17 Grand prix bikes myself so I am sure this would be a weapon of a bike and very unique as just the engine alone is worth the asking price amd a good Rd400 nowadays is easy 6-10k .Fox shocks Krober full ignition system (extremely rare )Tank is perfect clean but has dents from something falling on it Rare Charging circuit (lights) The top end was swapped out for a Reed induction (tz750) common thing if you had the cash back in the day. Cons:No kickstand or side stand (mount still intact ) ,push start only ,dent in the tank and side cover (per photo) I have never seen this done over all my years as a Grand Prix engineer r the years building bikes for wealthy clients  ,mainly due to the cost in doing it and how rare tz350 motor is nowadays.
