Chris300 Posted June 12, 2009 Share Posted June 12, 2009 These are rookie questions I know, but I just purchased a sweet low mile 1981 DT 175 and the previous Owner is still looking for the original manual. Can anyone tell me the viscosity and amont for the transmission oil, the spark plug gap, and the spec for chain adjustment? Thanks - Chris Link to comment Share on other sites More sharing options...
