Ok...I get right to the point. I need your help. This is my first four stroke and until this year I have had no interest in a four stroke. What tools do I need? What Parts do I need? How often should I change the oil? What should I look out for? How different will this thing handle than my yz252 stroke. What are the things I can expect to be different when I ride this baby. I ride with a lot of fast and smart riders. Many of them switched years ago from their 250 smokes to 450s. Nearly everyone got hurt and went to a 250F instead. They all think I won't do well on the 450 either. Please help me prove them wrong! Thanks for your patience with me. I am compulsive about doing things the right way. Why figure it all out the hard way when there are so many experienced guys around willing to help?
