I have a 2005 100 inch and the book that came with the motor says "20w50 motorcycle oil" and to use non-synthetic for the first 2000 miles to ensure that everything seats properly. Change every 3500 miles after break-in. I have been thinking of going synthetic now that I have over 5000 miles and live where it gets way hot.
The revtec engines are closnes of Harley Evo engines and use the same filter as the Evo's

how much transmission fluid does a revtech transmission take
If it is a 4 stroke then use SAE 10w-30 100% synthetic. If it is a 2 stroke use a 2 stroke 100% synthetic oil.
I believe you are supposed to use olive oil, but im not 100%!
100% synthetic.
SAE 10w30 100% Synthetic oil.
10w30
Change the oil/filter every 5,000 miles is you use conventional oil and every 8,000 miles if you use 100% synthetic oil.
100 to 1 100 mls of oil to 5 litres of fuel, use premuim fuel and good quality 2 stroke oil
