DG Perf. still makes them. I had a '82 250r about 11 years ago and I got one from DG and was very happy. I remember not doing anything with the jets back then. The plug was always nice and tan after the pipe went on (before it was a little on the black side). This time is the same, the plug is on the rich side. 1/2 tan and 1/2 very light black. I had to reduce the primary jet by one number and left the main jet alone , If I said that right. Its been a year since I did it. I just remember, the one I replaced was a "idle" jet. Anyways, I hope, its the same again, and I can leave those alone like before. I did get the tires and rims too 20x11x10 they are about 1/2" shorter and 1/2 wider than the stock ones (I think). Just thought I would share that. I will post some pics when I get some, since she is old and stilll in great shape.
