hey srh
main sounds pretty good, pilot will prolly need to be a 48, but 45 might work if it's pretty warm. everything else looks pretty close too
i think upping the pilot is supposed to help the bog
and did you get the header and pipe at the same time, or did you have the stock header on for a while. i was wondering how much that header you have helps. i am really impressed with the dr.d so far tho.

I'd run a bit higher main jet ... Sparks recommends a 175 I believe . Also bump that pilot up to atleast a 45 . The fuel screw is underneath the carb and is ressed in ... you'll need a long skinny flat head screw driver to get at it . 2 1/2 turns is what is recommended with Sparks .Originally posted by tgyolai
