you may need to get your bike set up by an experienced mechanic , im not saying you cant do it but if you never did any carburetor work heres why

whether you do a jet kit or not , if you do a slip on or a full system , you will need to adjust your idle mixture screws . the idle mixture screws on cars and motorcycles today are capped with a brass plug by the manufacturer , they cap them so you cant ( in theory ) change their setting , ( it has to do with pollution requirements ) . but to get the motor to run correctly after you change the exhaust , you need to adjust these screws .so you gotta drill out those brass plugs . unfortunatly those brass plugs are on the bottom of your carburetors . so you need to remove the carburetors from the motor to get to the plugs and then the screws . the screws are right under the brass plugs if you drill too fast or deep you will destoy the screws . i took this picture to show my brother what im showing you , heres a photo of me drilling the plugs .

So what are you adjusting for? My guess would be that adding the exhaust opens up the air flow so you need to open up the fuel mix to match it, right?

exactly;

and if you dont mind taking a bit of time,make sure not to touch the screw in there,and once the plugs are out,screw each in till they lightly seat;please make sure to count the number of rotations in 1/4 turns,take notes for every carbs...you"ll probably find out that every carbs are setted differently!

we had a theory about this 3 years ago talking about the matter;most came to the conclusion that the factory guys setting the carbs did them all on a friday afternoon with a few shots of sake...lol

but i brought my theory,being that different carbs with different specs and machining tolerances would need carefull tuning according to its flow properties(and the flow from the inlets tracts,etc)thus the importance of taking notes on each and everything you modify.

could be of help if you decide to go back to stock exhaust one day being to sell the aftermarket stuff separately or else.

after all,why was i bringing up that theory of mine?

ask yourself this question:"was my bike running flawlessly off the dealer showroom floor?"

answer: yes it was...then again got to take into consideration the new full system properties or even the one from a slipon...

oh man.
