Hi all,
Working on a 01 SV650S with 35k miles, backfires at idle but runs like a gem above 2k rpm. Stock headers with a yoshimura Tri Oval dual exit pipe, stock intake, tank lifted, 17.5 pilots and 136 mains. Pilots are fresh, mains were pulled and cleaned, and stuck some fresh CR9-E plugs in.
I'm open to ideas, air getting into the exhaust somewhere? needs valve job?
Thoughts?
Thanks

Problem solved:
Checked the valves, exhaust valves were a little tight. Adjusted the valves back into spec and synced the carbs. Fixed the popping issue at idle.
