Carbs
Hey,
I dont know much about carbs but I hear of people tuning them when they setup their machine for the first time. All I have done is adjust the side screw which adjusts how many rpm it idles at. Is there more adjustments that I dont know about? It seems to run good but maybe it could be even better. |

unless you add a intake and exhaust you dont need to mess with the main or pilot jet..
when its at idle give it a quick revv if it hesitates or bogs as soon as you hit the gas.. you need to play with the air/fuel screw.. which is that little screw on the front bottem of the carb right next to the bowl |

You can move the clip on the big needle to aid in cold starting. If you bike is stock there is not much that needs to be done.

These carbs are rich as hell from the factory, sometimes lean as hell, really depends on what brand you buy. They can always use tuning of the pilot and main and needle clip position for better performance. If you want some basic carb information, search google for "spankys jetting guide" and you'll get some understanding of the tuning process. Start with your pilot jet and find out what size you need by observing the number of turns of the fuel screw. When that's said and done, check your main by doing a plug chop test. Adjust by a size at a time until you achieve a decent plug reading. When that's said and done, the needle clip position can be adjusted for best performance, you will have to play with all the positions and see which one you like best. |

Your right, and I honestly apologize.
I must have taken my a$$hole pills that morning. Sorry bud. You are right as well in some respects, most people aren't going to want to mess with all of that or don't know how to when they first get their bike. These bikes will run well with the stock jetting, you don't have to go in there and play with jets. Brent |

Or.....just jet the thing for cooler weather, and live with it a bit rich when warm.
