| Remember, you are the one onsite - You must be the eyes, ears & hands - But you must accurately, thoroughly, communicate the facts to the remote helpers - If you have some ideas or comments, post those in a separate paragraph from the actual tests & results so as not to confuse assumptions or theories with the known facts. | Remember, you are the one onsite - You must be the eyes, ears & hands - But you must accurately, thoroughly, communicate the facts to the remote helpers - If you have some ideas or comments, post those in a separate paragraph from the actual tests & results so as not to confuse assumptions or theories with the known facts. | ||
| + | Video (or pics in other cases) is very helpful, especially once a 'problem' is seen by the forum as unusual - We diagnose problems based on what we know, what we are told and what theory says should happen. | ||

| + | We generally suggest doing certain tests because we have found the results to be important indicators of where to look for the source of the problems. Often times, the original poster (with the problem) doesn't understand why we're asking a certain question or when given a list, simply overlooks EACH and EVERY test check suggested. But, in most cases, EACH and EVERY test was intended to produce usable information toward a solution. | ||
| + | |||
| + | Long-distance diagnostics requires lots of accurate and specific information so that 'WE SEE' what you see. and maybe see what you don't see. And that is where having a video (or pics) of 'the problem' can be evaluated & assessed for help from afar. The perception may be the same as you had, but it might also be perceived quite differently because of other's experiences and knowledge, even though they are remotely located, trying to assess what is actually happening and why. | ||

| - | If the bike will not start, find out if the problem is fuel or spark related. The quickest way to tell if the 'No Start' problem is fuel, is to give it a quick shot of 'Starting Fluid'. If it tries to start and runs a second or two, then the problem is likely the fuel supply (somewhere - tank, petcock, carb, etc.). If it doesn't try to start with this short shot of fluid, then it is likely missing the spark. You can test for spark by pulling a plug or using a spare. Put the plug in a plug wire, ground the plug to the engine fins, and crank the engine. Doing this for each spark plug wire should show a good spark across the gap. | + | If the bike will not start, find out if the problem is fuel or spark related. |

If it tries to start and runs a second or two, then the problem is likely the fuel supply (somewhere - tank, petcock, carb, etc.). **DO NOT continue to use starting fluid to run the engine.** It will quickly wash the cylinders of oil. One shot should indicate whether the issue is fuel - then track down the exact source of the problem. | ||
