There's an abudance of information out there and especially on this forum. A little research will yield all the results that you need. First pick up the pods. Most perfer K&N item 2340 I think. Emgo makes a cheaper pod which I've also used for a number of years. The diameter of the pod you need to by is 54mm. I've used 52mm as well, but they're pretty tight and tend to come off when tightening. You'll also need to rejet your carbs. Most people who make the change from stock to pod filter go with 90/120 jets. Both of these will be MAIN jets. Install them and tune your carbs according to performance and check your spark plugs to find out if you're running too rich or too lean. Thats pretty much the whole of it. Are you still using H-Box with stock mufflers?
