Fuelling issue and backfirel.

  1. Hey guys, I've had my 04 R6 for a few months now and if I rev it up to around 8K or so it will backfire quite loud, is this normal for a bike with a slip on exhaust, I was told it was by the bike shop. I always thought a backfire was excess fuel that hadn't been burnt. Also every now and then my bike will go flat between 4k and 6k, sounding like it's blocked and doesn't fix itself until I give it a few good revs past 8K. Any suggestions wouldbe greatly appreciated.

  2. what fuel are you running?

    are you getting any lights or errors on the dash?
  3. Fuel

    I run it on 95, I think. Caltex Vortex. Nothing appears on the dash at all, but on the 04 model I only get very little info on my dash any way.
  4. Lean or rich can cause backfiring, the slip on has possibly leaned it out slightly... Have a play if you're up for it, or get it dynoed & tuned.
  5. That is fkn awesome! I wish my bike would do that. :grin:
