This is a topic that has been on my mind for a long time, I have used the analogy with my son of an old tired dirt bike. Some times you have to push it to get it started but at some point it has to give you some indication it will take off under it's own power other wise you just look like an idiot out there pushing around a piece of junk. For the olde crowd here we are talking about beating a dead horse. Part of the problem is when the motor cycle looks fantastic but won't quite run. We as parents want to know what part needs to be adjusted or replaced to take full advantage of what you've invested in recognizing all the benefits that could be gained given the best/right effort. There have been a number of times over the years where I have had to all but bodily put my son in the car and endure an angry silent trip to the ball field and then on the way home he thanks me for making him go.
