Blocking the ais will help. But what will cure it completely is a pc5. When I got mine flashed from Ivan and a pc5 no more Backfires or burps and I also gutted the cat
Looks cool. I've never had a problem with my mirrors I can see behind me at all times but it would be nice to have it right in front of you. But I already have a 1200 helmet and I need racing helmet and gear for the track. So I don't lose my license.
I was lucky and have ohlins front shocks and 6 piston brakes and ohlins rear. No complaints with those but I think it's close to 4k for the setup. I got the Ivan flash and every thing else except yosh headers. Dyno at 137 hp it gos pretty quick and 83 in first with -1 in the front.
