no one mentioned re jetting, least not in this thread. Why did you say that? re-jetting is done for good reason not for just something to try to fix 'spluttering'

Having said that and to answer your question, there are several jets in your carb, the one lowest down into the float bowl is the 'Main Jet', this will have a number on it and that number gives the size of the hole drilled through it. To fit another with a different number, say a bigger number means that it will have a bigger hole through it, this means it will allow more fuel to pass through it given the same pressure differences and the more fuel it allows through the 'Richer' the mixture will be. Dont mess with the jetting sizes unless you have modified your bikes filtration, exhaust etc.
