Hey could I ask you some things, Please?!

1) When you got the Big Gun Rev Limiter did you feel a diference and by how much?

2) Where did you get the Big Gun and how Much?

3) W/ the air box vents where did you get them?

4) where did you get the vents?

5) Did you feel a diference?

6) Did you have to rejet the carb?


<u> THANK YOU SOOO MUCH! AND IM SORRY I DONT HAVE AN ANSWER TO YOUR QUESTION</u>



PS You know once you get the 16T sproket you'll loose a ton of torque.. but gain some top end.. I got a 12T and Gained tons of torque but lost the top end so now I have to get it back w/ cheep ways like the big gun rev box and the vents maybe..

THANKS AGAIN!

the rev box will not give you more power. it will raise your rev limiter.
