I just purchased a full yoshi comp system, I am currently running with a K&N airbox lid off and a hrc end cap...not hrc kit though. My questions is will I have to change the needle and pilot jet with the new system. and if so do I have to take the carb off the bike to change the needle and pilot. Also when you talk about needle clip position which is richer and which is leaner. sorry about the newbie questions. going to try and jet the bike myself, any instructions would be appreciated.

Just swap the main jet for now and it shoud be fine, you might have to adjust the air/fuel screw on the bottom of the carb also.

luke is right, you only have to replace the Main jet. I would replace the needle also. On the needle, if you move the clip up, it leans it out. If you move the clip down, it richens it up. No you dont have to take the carb off. For the main jet spin the carb sideways a little by simply loosening it up on both ends. Juts a phelips screwdriver. Then take a wrench and take the 1 hex bolt off the bottom of the bowl, and there is your main jet. Get a socket and take it off, and replace with the new one. The needle jet is a little harder. You have to take your gas tank off, take the 4 screws off the top of the carb. take top of carb off, look inside at the very bottom, you will see 2 more little screws...Use a magnitized screw driver and take those screws out. pull the throttle out of the way, and reach down there with a pair of needle nose pliers and grab the needle and pull it out. take the clip off that one and put it on the new jet. and put it back together....If you are running open air box start with the needle on the 3rd clip, and you can adjust from there....if you are at sea level you can probably get away with the 4th position witch will make it a little richer...hope this helps.
