Since putting an FMF Powercore muffler on the bike, it has become hard to start and backfires slightly. Is this normal or do I need to change the powertune to correct it? If so, what is recommended to change it to?

Couple of questions:
1.) Did you remove the air intake snorkle yet?
2.) Did you install the race ECU module?

1) No we didn't remove the snorkel
2) Are they parts of the off road kit for the WRs?
Thank you heaps, I'll keep you's posted thank you to you both

Remove the snorkle. Then if you have the programmable ECU, have it programmed or buyt the power tuner to program it. It's going to be extremely lean otherwise.

It will still be lean at idle unless you get your hands on a FI diagnostic Tool and change the A/F mix.
