Need some advise please

I just got me a new 2012 rs and I've got 125 miles on it I ordered a two brothers slip on when I picked it up today I installed it and took it for a test run and it runs but misses on take off. I don't know if it is related to the install but I figured it was because I didn't notice it with the stock pipe. What do I do

Your bike is running too lean. You will need an O2 sensor that enriches the fuel mixture. Juice box, or modified O2 sensor will do the trick. I have the modified O2 with dual exhaust and it works fine.

Try disconnecting the battery (negative post preferably) for about 15 minutes, and when you start it, let it idle for 5 or 10 minutes. This helped with the Hindles.

Ok I'm going to give it a try I've unhooked the battery for ten then hook back up and let idle for 15 I'll give an update after I get done thanks for the advise

Well I unhooked the battery positive post didn't see that they said negative anyway let it set for 15 mins then let idle for 15 mins it ran a lot better but still is not right it sometimes doesn't take off good and pops out the pipe sometimes and ideas on what to do now

You need one of the fuel controllers that are out there .

Power commander 5 is auto adjusting -- air/fuel -- but you have to install a sensor into the exhaust.

The two brothers juice box ( their are 2 ) regular or pro -- you use their maps to control the air/fuel mixtures or you can take it to a shop the dyno tunes just for your set up .

I'm thinking about putting the stock pipe back on I'm getting to old or the two brothers pipe was a little loud on a lone cruse I like it around town the other thing is I can't really here my wife very good with our new head sets on?

I put the stock pipe back on for now. I think the new pipe opened it up to much and didn't have enough back pressure for the computer to compensate they do make a optional tip that is said to make the pipe quieter so I figured if it was quiter it must have more back pressure after I reset the computer it ran alot better but not perfect so maybe the tip is all it needs
