Guys im getting the 02 ktm 250 excf

Aaaaand I have a few questions, what oil should use, I have some 10w 40 genuine kawasaki oil for my kx250f, will that work? Also I would like to restyle it eventually and it doesn't look like there is any restless kits for them, is there some plastics that would work on it or not. Thank-you in advance
