DT1 Frame ID Help #11
It does appear that there are some faint remains of a number on the left side pic.. ( hard to tell via a pic) but a gentle clean up of rust and a magnifying glass could prove worthwhile.

On a 1970 DT1 the number is stamped on left side, reading upwards. Your last picture shows the location with some obvious grinding marks obscuring the number. Still visible are what appears to be a 2 in the last VIN position, as well as a 1 in the third or fourth position from the end. All other numbers are illegible.

Experienced auto theft detectives have a technique whereby they will put an acid on the area that has been ground off and frequently an outline of the missing numbers can be made to appear again, faintly. That technique may very well work here, but in California at least, they will not attempt it unless they have good cause to believe they are looking at a stolen item and seek to identify it as such. I know of no official police agency that would do this procedure simply to help you restore or register your frame.

Do you have a title for the bike? Do the VIN numbers on either the engine or the title match the placement of the two numbers that can indeed be seen still? That could be a starting point to have your frame restamped with the original number, but again, it may well be easier and more cost effective for you to begin with a different motorcycle that has all of it's numbers/paperwork in order and simply use the questionable bike for donor parts.

It does appear like some malfeasance may have occurred on this bike.

Thanks for the response. And no I don't have any title with it.
