Thanks. Found some information on the internet that showed me the DT was a 250 only so yes, sure it it not the original motor. I am still trying to determine the exact dates they were made but that is proving difficult. Guess that is not so important but will keep looking. The bike is silver in color. As far as value goes, I would suspect that mis matching motors won't do much good for sure, and finding another probably not worth the effort. Guess it will be a fun toy to rise around for a while though.
