The_Atheling Posted February 4, 2017 Share Posted February 4, 2017 Hi All Apologies for the following strange request: I have just recovered a 1980 DT from a barn - I bought it off a mate who was emigrating more than 30 years ago and it has sat there since. Remarkably, I think it could be resurrected. My 17 yo lad is keen to do this. Problem 1 (there will be more, I'm sure), I can't remember if it is a 125 or a 175 (The V5 disappeared years ago and there are no capacity decals on it). Is there anyway I can tell from the frame number or do I need the engine number? I assume it is the frame number on the headstock - it's a bit ropey but I think it is 02168?X?. I believe that 125 and 175 parts are pretty interchangeable, but clearly as a learner at 17, its important for my lad to know. Any initial thoughts? Many thanks Link to comment Share on other sites More sharing options...
Moderator Airhead Posted February 4, 2017 Moderator Share Posted February 4, 2017 175 has a 6 stud cylinder head, 125 has 4 stud...and for that matter it will have the capacity on a casting mark at the bottom of the cylinder, for example 171cc Link to comment Share on other sites More sharing options...
