Hi all, im Richard, ive just bought an 08 WR450 and ive come accross this site while searching for info. I must say it looks a great site and full of info! Anyway, ive seen the FAQ and that answers most of what i needed to know. But i cant seem to find much about reccommended oil. What grade and make of oil would be good for my bike? Its a 2008 model and it had 14 miles on it when i bought it im the second owner, it now has 50 miles on it I know oil changes cannot have a set time limit or mileage put on them, but how often do you guys change yours and how do you ride the bike? I dont ride it that hard really, and wont be racing this one, just using for a bit of fun at the moment as i cant really afford to race again for a while. Ive always had 2 strokes before and know them inside out but 4 strokes are new to me. What i assume is a catch tank for coolant overflow behind the left side panal, its more or less at the bottom and i can just see the green coolant at the top of the pipe. Is this how it should be or should the level be higher? Ive also noticed in the spares, some different jets and needle. These are unopened so i assume it still has stock jets? Its had the baffle and restrictor removed from the exhaust and the throttle stop screw taken off, but the grey wire is still connected. It seems ok as it is, but would i actually benefit from removing it as it runs fine as it is now on what i assume are stock jets. Any other general info and advice welcome because as i said this is my first 4 stroke and i dont know a great deal at the moment. Thanks in advance, Rich.
