O.K. so Ive decided to adjust my main jet, but in the service manual it does not show how to access it. It shows how to pull it out of it little vaccum boot and how to adjust the clip but not how to get to it. I have not removed the carbs, just have the airbox off, but im not really sure what to start removing. I dont see the boot, is it right in front of me and Im stupid, or is it under the carbs and they have to come off?
