In for the service at Moto Rapido on Tuesday. Have run it in by the book with the Akro's fitted. It still backfires big time from 3 to 4 to 5 and I find it a little annoying now. its not just a pop its a proper BANG. Anyone else suffer this.
Mine does on the same changes as yours. Had it's first service last Saturday, I'll find out tomorrow if it still pops and bangs.
Service complete. Still pops and bangs but a little less now that I am changing at 7 - 9k range, a smoother change if anything. Its nice to have all of those 1200 cc + to call on at last. Now to book a track day.
