I just added the clutch, pipe, jet and filter to my 2001 Scram 500. During my test drive I noticed that it backfires and pops after high revs...I tried adjusting the carb from the recommended 3 turns out...and then 1-5 turns out. It has the same results in any of the adjustments. Any ideas?? If you have made this mod with success and no troubles as mine...please let me know. I will speak with RCR on Monday, but would like to ride ASAP...you understand!!!
