You can use stockers, several builds have been done with stock carbs and good results. You will here that you "need" 33-35mm carbs. But you don't. For a trail motor stockers will be fine.

Agreed, you will also want new pipes and cool head... My serval runs very very well, I have a full list of my mods on my profile...
