looks like it. 

You can make it a 350 by swapping top end over to R5 or RD parts.  But great as 250.

Thanks Mark!
I think I am gonna keep it a 250 because I am going for originality. I stripped completely down every nut bolt. Lucked out crank, bores and pistons Look great.  Clutch disintegrated.  i am cleaning and trying to restore everything.  I think I can recondition cables and I am past broken carb body.  Already onto 2 nd gallon of evaporust.  Rattle can repaint, some re chromed fenders.  Rims too rusty to save and seat dust.  I think I might try my hand at re lacing  and found a dude on eBay who makes seats.

I might have a seat core.  I have a pile of DS/R5/RD parts.
