-Troubleshooting can be very difficult sometimes to the person that has to physically do it. You're there. You hear it or see it and sometimes the hardest thing to do is to tell it to someone else. Another hard thing to do is to detach yourself from what you (think or believe so strongly in) to strictly what you can prove. It all boils down to your specific belief system. ​//You filled it full of oil last week so it couldn'​t have been too low//, so you didn't check that. So, a day later after filling it with oil, your friend on the back burnt their leg or foot on the exhaust, went berserk and not knowingly kicked the oil line damaging or kinking it on a long trip. When you believe that anything could have happened to it, you stand a better chance of diagnosing the problem. Below are some easy fixes and some very difficult ones as well as cheap and expensive ones. Keep in mind an unhealthy bike doesn'​t care if you can't afford it or know anything about it.

 Engine oil is like blood in the veins. Running a bike too low or without will ultimately lead to engine seizure. Engine oil is like blood in the veins. Running a bike too low or without will ultimately lead to engine seizure.

     * Wet sumping occurs when the crankcase fills up with oil. The crank has to turn in an oil bath when it's really designed to run in open air. The crank running thru the oil heats it up and adds lots of bubbles. It also really cuts down on the available power. The scavenge pump picks up the oil and sends it to the oil tank. The hotter the oil, and the more air bubbles in the oil, the harder it is for the scavenge pump to move the oil. So, the oil collects in the crankcase even more.  ((blacksmith_wills of the XLFORUM http://​xlforum.net/​forums/​showthread.php?​t=73243&​highlight=sumping&​page=2))     * Wet sumping occurs when the crankcase fills up with oil.

 The tables below have 2 separate but equally important columns; Possible causes and Possible affects. It is just as is important to know what happened as it is to know why it happened. I.E., a broken piston ring can be fixed but if the cause was low oil pressure and that was not addressed, it'll happen again or worse. ​ The tables below have 2 separate but equally important columns; Possible causes and Possible affects.

 Transmission noises are usually not what you want to hear but there is a natural symphony that happens sometimes when changing gears. The harder the push is on gear shifter, the harder the shift forks smack the gears around and the noise is more audible than if shifting easier with a quick smooth motion which sometimes sounds like a light hollow clinking as in two plastic parts shaken in a sandwich bag.  ​ Transmission noises are usually not what you want to hear but there is a natural symphony that happens sometimes when changing gears.
