Posted October 9, 200816 yr hello , i am new to this form and first post I just picked up a 1973 dt 250. It was a little loud with the tuned pipe, so I installed the stock exhaust it came with as well. It is running quite rich. The main jet is #210 and pilot is #80. Would someone know if these are stock or bumped up because of the pipe. Any help would be appreciated.

Hello Glenn, I would expect that the jets (at least the main jet) were indeed "bumped up" for the tuned pipe, the info will no doubt be found in a workshop manual.
