slow start on modded 80

hey guys need some help. I have a 2005 with a cgr motor and clutch work. Front and rear clutch just done about a month ago.It has a 20mm carb and a new trinity pipe also a kn air filter. It has a slow takeoff but than it runs like a jack rabbit once it gets going. Do you think its in the jetting or the rear clutch. I'm not sure if the clutch is supposed to be set up like this. I live in louisiana and my jets are a 115 main and 50 pilot. Any help would be appreciated.

I'd chime in but I'd much rather you ask Chris first.

Chris is a great guy and I am sure he'd be happy to help. :)
