infamous RAK mod - thoughts?

Hi guys,

I got this awesome roadburner street pros exhaust installed with dynojet s1 kit (3rd groove on needle n the cj090 jet) Bike ran n sound like a dream

Then I did this RAK mod n it all went to hell lol Apparently, stage 3 jet dynojet kit don't exist.

The bike would bog down when I try full throttling. Around 1/2 throttle. It Idles great n runs great until nearly 1/2 throttle.

I cover up the hole I had made on the RAK mod n it goes pass 1/2 throttle like butter.

Can anyone help? Do I need to move my e clip to the 4th or 5th groove for the RAK to work? Anyone had this issue? Any input would be appreciated.
