Tell your friend too ask the dealer that shot it down to write out a legal guarantee that the doohickey and spring in his bike will never fail, and that all resulting damage will be paid by the dealer, in full.
When the dealer refuses, spend the $40 and address the issue before it causes catostrophic failure of your engine..
$40 is pretty cheap Peace of Mind, if you ask me.. I've seen 4 broken Doos or springs removed from KLR 650 motorcycles. 4 were broken out of 10... 40% failure.. $40 fix.. Seems simple to me, but I did mine 3 years ago and haven't had to worry about it since. $40 well spent..
