I have noticed that long track 250 single owners have been ending up on the side of the track too often due to engine failure here in Northern California.  It seems we have been running too lean.  Is there anyone that could go over the basics as to how to establish a baseline for jetting, a good starting point, and what preparation should be done at home so that when you get to the track you are not overwhelmed.  Also, I have noticed that a common sticking point (pun intended) is mid throttle jetting point.  Anyone care to give advice?

I realize this is too broad but it is off-season and I could use some help.  If we don’t help each other so that we can at least start fininshing some races there won’t be anyone left to race with :)
