I purchased a 2010 KLR last September which I have been very pleased with, but when sourcing out some vibration at certain RPM noticed the stock engine guard was cracked at both lower mounts. I purchased a new stock one as my off road experiences will most likely just be forestry roads so not overly concerned with a heavier aftermarket guard. I immediately noticed after installing the new guard that I was getting a "reverberation sound" coming up from under the gas tank. It is a very annoying sound not there previously and I verified it by taking the guard off again which eliminated the sound. I remounted it using rubber washers but the sound soon came back and taking it off again found the heat fried the washers. Anyone here have a similar problem and found a solution? I am thinking of drilling holes in the guard but strange that the original did not do this unless it was because that it already had cracks to diffuse the sound.
