High idle.

[Sruiz67]

So I just did a new top end. Used a wiseco piston. Replaced reeds with oem. Rebuilt and cleaned carb. Put everything back together and the darn thing is idling really high. How do I get it adjusted correct? When I did the carb rebuild I put new needle in at middle slot on the clip. It's all stock and it's an 03

First check that your carb slide is in correct and not backwards. Do a leak down test.

Let me also explain that before I did the rebuild. It wouldn't run right unless the air box was off. So I thought it was too much fuel so when I rebuilt the carb I pulled the old needle and it was on the bottom setting of the needle clip. To me it made sense that it was letting too much fuel in and that was the reason for the bogging when the air box was on. So I read on this forum that stock should be the middle setting on the needle. So I did that and replaced the air box. Now it is idling way to high. I need some help? Also the piston is 66.5mm if that matters. I'm stuck
