Ok guys, this may be a questioned asked often but a need some advice. I have on 05 TRX450R with a 178 main and a 50 pilot. I'm running an HMF slip-on with the queit core insert. A while back when I put the quiet core in (the hmf) I was having issues with throttle response. So after posting on here and getting some good responses I changed the pilot to from 48 to a 50, the main from 185 to 178, and played with my air/fuel screw.
All has been fine for some time now but it seems to backfire a lot on deceleration. Noticeably more so then usual. I need advice on whether I need to re-adjust the air/fuel screw or possible some other adjustment?
Thanks in advance!
