I just did this mod and guess how many times I had to open up my carbs?
5 times due to my ignorance and impatience. Read ahead to learn from my downfalls and it should save you some time/troubleshoot if you run into same problems I did.
First of all, GET THIS TOOL!!!

First time I did it, none of my screwdrivers or wrenches would fit into the back screws so I ghetto rigged a phillips to a socket to another one to a metal spoon handle (Yes you read that right). It worked fine but was a pain in the ass to find what out what fit and what didn't fit due to the frame being in the way. I then added two #4 washers because I have a two bros exhaust, fired her up and the engine would die instantly.
Second time I took off the carb caps was to revert back to stock. Nope, same problem.
Now I know I definitely hooked up something wrong so I looked at the carb diagram pics and found out I hooked up one of the hoses into the carb vent hose, silly me...
Third time's the charm right? So I rehooked the hoses correctly and added two washers again, fired her up and she was great! I took her for a ride down the street and BAM, nothing above 6k rpm. I was WOT and the rpm would stay at 6k so something was definitely wrong.
I thought my bike was running too rich so I reverted back to stock ONCE AGAIN. Did that fix it? NOPE...
I googled around and found out that this occurs when there is no vacuum (air leak) in one of the carbs. I started to worry thinking that I had ripped one of the rubber diaphragms then I realized I screwed on the choke cable holder in between the carb plate and the carb. So finally I put everything back together and now she runs PERFECTLY with two washers with a two bros exhaust and the snorkel delete!!
I was very impatient and rushed so I wasn't paying attention on where everything went and didn't have the right tools.
tl:dr: Get that right angle screwdriver before attempting this, have the diagrams/pictures out of what hose goes where and what screws go where as many people have connected them wrong. It'll save you hours of troubleshooting!
