Ok well im new to this forum but it looks like it will be helpfull! I just picked up a 1993 Honda 300EX for 700 bucks today and it came with a Big Gun exhaust, Rear studded tires and the non studded ones, and nerf bars. It runs pretty good but needs a carb cleaning since its been sitting for a while. It also definately needs an oil change, its pretty low on oil and its black. My friend had a 2000 400EX and while doing the oil change, he broke one of the bolts for the oil filter cap, is this common? Also, what oil should i use? Just a 5w-30 or 10w-30? Im looking forward to riding this over spring break and want to tune it up just so its good to go! Thanks!
