And when one of those spraybars vibrate loose at wot....
do u have any pics of where u have the tank an setup ?
I have the Gixx1300 spray bar on my 08 its a nice piece but I would say get your bike to a dyno I put a 28 jet in mine could hardly feel it so I upped it to a 32 then took it to the dyno I also added fuel via my lcd display 4% mid range 10%on high and the air fuel ratio was 14 to 1 which is way lean you can get away with it for short burst such as the drag strip but not reccomended for top end runs. The solution is 2 power commanders one for primary injectors one for secondary injectors on a switch when you arm or activate the N20, or you could buy the Bazzaz box and Zfi tuner as it runs both sets of injectors.
Why would you need two power commander III USB? There should be no reason at all for that when you adjust the Power commander it is setting the bottom injectors and they lay off a bit at 8000rpm I believe so when you increase them it richens the whole range. They dont shut off they just decrease so the power commander can increase your intire range. Correct me if I am wrong but this is what I have found. As for the bazaaz I have herd alot of good thing about it nothing bad just a little different but I have herd nothing bad of the power commander III USB either.
