Well I just got back into riding after having to sell my 2003 KX250 for truck tires and shocks. Found a pretty well setup 1999 KX-250. Got a couple questions though. Is the 99 motor much different then the 2003 motor? IE will my shop manual for the 2003 motor work for me or is everything gonna be different? Im mainly interested in the torque values for nuts and bolts. Also (since the 99 came with a busted clutch cable) does the 99 ride much different then the 2003? I ride trails and tight single track. Its geared 13/50 right now is the gear spacing in the transmission different then the 2003? I may have a few more questions later but thanks for the info!
