yea those instructions are very helpfull, i almost jetted it for the first time but the only reason why i didnt jett it right was because i made a slit in a plastic part of the carb cuz of those damn screws are so tight. but besides going out and buying another piece, its REALLY easy
Next time I rejet my carb ill make a how-to on it. Yet it is very simple to do and it only takes me a couple minutes to rejet after getting the carb off.
Hell im even more lazy then that, i don't even take the carb off, i loosen the clamps and twist it to one side. Theres your 5 minute main jet chainge, the needle is a diffrent story, you have to pull plastics and the tank off on the rappys, so thats like a whole 15 minutes.
