Might be a stupid question, but oh well... I know that if you make you main jets to rich that you get a stumble at full throttle, but how do you know if you make the needle position to rich. I have it at the next to the last clip position, but was going to raise it to the last position.
Oh and this is on a Banshee, the problem I'm having is it runs hot when I'm really working it in the dunes. Going to go up one more size on jets also... from 300 to 320...
Any thoughts would be appreciated.
Thanks

I personally don't mess with the needle positions, I keep in the middle and leave it there. If you ride between 1/4 to 2/3 throttle then you are on the needle. anything over that is on the mains...

sounds like you a tad lean on the jets

next to last from the bottom right? I would say go to the middle position then work from there. Read this link it might help!
