I have to safety wire the oil drain plug to race this bike in WERA/AHRMA. I am new to the model, but after reviewing the shop manual, it looks like there is: 1. An Oil Tank Plug. 2. An Oil filler plug/cap. 3. Oil Filter Drain plug. 4. A Drain bolt below the Oil Filler plug. 5. Crankcase drain plug. These will all have to be safety wired apparently. Having not changed the oil on this bike yet, do you open up plugs 3,4,& 5 to drain separate areas? Another issue, in racing this bike with no air filter, just screen. What's the jetting change needed at the carb? We are talking roadrace, not motocross. The bike is outfitted with 17" wheels, and Yamaha R1 front end, and revised rear shock. http://www.home.insightbb.com/~arctec/450.jpg Thanks in advance.
