I hear you Saul , I have no idea what's up with that , they were both raised in the same manner, one is completely self reliant and does all of his maintenance work on his bikes and the other relies on the other one , don’t know if it's complete lack of confidence or its my fault, has basically no interest in turning wrenches...30 years-old old now and Im still changing the oil in his corolla....I honestly beleive it's something your born with...some have it...and some don't....
