I'm not sure about where you can buy the boots. I got mine from the dealer. Are you over tightening the clamps? I've almost cut mine in half by tightening the clamp too much. (also with K&N pod filters.) You can support the weight of the carb with some high density foam rubber between the float bowl and the engine case. You can also hang the weight of the carb with tie wraps run up to the upper frame tubes.
