Now ime confused .sent yambits my frame and vin number came back as a ft2 1972.looking at dating info on here its listed as a ct3 being completion green .only listing for dt2  is gold .it a enduro.any help thanks 

Post your numbers here on this site. Everything I see in your one picture indicates 1973 DT3 250cc bike.

The best ID info is available in the Tech Library here.  Sure looks like a 73 DT3 but you really need to check the VIN as parts can be swapped and repainted.

Tiger, where are you getting "CT3" from? That's twice you've used it now. The CT bikes are 175cc.

As Pedalcrazy and MarkT said, that paintwork is for the 1973 DT3, but it could be that a previous owner applied this colour to a 1972 model DT2, and so comparing your frame/engine numbers to those in the VIN tables here is the only sure fire way of finding out.

Bike  recent import from use .thanks for info   

Yes, 1973 model DT3 (see extract of VIN range from the Tech Library below). You might want to get the engine number corrected (to show the "F") on your V5 logbook.

The year of manufacture shown on the tag on the frame (if it's still there) might be 1972, but this is because Yamaha often manufactured their frames a year or so in advance of sale to the public. This means that, here in the UK, we'll often get an age related plate from DVLA that relates to the year before a model was actually sold here!
