I have an 02 1200 sporty. Installed a thunderslide kit, put carb back on bike. Now when I try to start the bike it just pours fuel out of the little ports on the inside of the butterfly. Any ideas ?

 

Take off the carb again and reset the float adjustment you whacked putting in the kit. It's letting in too much gas and over filling the bowl. Check for a pinched over flow tube also since it's coming out the idle circuit but may be just high enough to not emulsify with air and just sucks gas out the port without hitting full over flow level and coming out the over flow tube. Set your fuel mixture about 1 1/4 out to start.

 

As said, float level is more than likely buggered.
