    Billy, did you ever get the jetting specs?

    Can someone just post the jetting specs for GP800R carbs w/ accel pump removed and aftermarket flame arrestors added. I PM's OsideBill but he said he has never re-jetted 800R carbs and couldn't help me, I've emailed Carl at IR but haven't heard back. I realize the 800 engine isn't the most popular but some has to have re-jetted 800r carbs for f/a. I've spend hours searching this site for the answer and have yet to find the answer.

    Thanks,

    Jeremiah
