Hey what’s good gixxer fam. So I did the clean air mod to my bike last winter for stunting , Blocked off all hoses to airbox except for crank case, put a small filter on that one. Started up fine took it down the rd and red fi light came on. When the light came on the bike started slowing down a A LOT quicker than normal. I could gain mad speed but right when I let off the throttle , the bikes engine braking would slow me down tremendously. Threw an idle adjuster on and fixed the problem with the deceleration all summer. Now this past weekend no matter what I can’t get it to run without misfiring. I ran it at 3k rpm’s but now it just misfires if I run it over 2k. Just started happening over the weekend. I can get a video if that helps and only other thing down to the bike is a m4 slip on
