Hi guys great forum.I'm only just getting into dirt bikes and know very little bout them. I purchased a TM 250MX 4 stroke a few weeks ago. The guy I bought it of said it was an 06 model but when I sent the V.I.N to my local dealer they said it was an 04 model.So that leads me to my first question. Is there much differnce between the two?Either way it's a great bike and has been really easy to get comfortable with.I've put about 5 to 6 hours on it and want to give it a service and that leads me to my second question. Do these bikes have seperate geabox oil? If so what oil should I use and how much? Below is a photo of my bike.Thanks in advance for any help.
