How to set the timing on a maxim x? - 1985 Yamaha XJ 700 X Maxim

If you're looking for the service manual for an XJ700X, you should know that the factory manual a) has errors and b) doesn't distinguish between the 85 XJ700X and the 86 XJ700X... and there ARE differences. In any case, you're much better off visiting www.xjcd.org to order what's known as "The XJCD set". That set of CDs contains a lot of updates, clarifications and corrections that were unknown at the time of printing 28+ years ago.

I'm going to guess that "pit ####" meant petcock :-) and yes they do "go bad" in a number of ways. There is a diaphragm inside which can crack over time. There is also a diaphragm return spring which may break (I've seen only one like that though). But most often, the use of fuel with ethanol in it will cause the breakdown of the plunger seal. When that happens, the petcock "leaks".... not externally but internally. The Maxim-X has a vacuum operated petcock which is supposed to only provide fuel to the carbs when set to PRI (prime) or when set to ON while the engine is running. When the engine is off, there should be no flow of fuel. But the damaged plunger seal allows fuel to flow from the gas tank to the carbs at all times, even when the engine isn't running. When you combine that leak with a leaky float valve, the result is usually a crankcase full of gasoline - clearly not good.

Hope that helps.

i have got a maxim alarm clock and i don't know how to use it.I think i threw the instructions away would you be able to tell me how to set the time please.

Click Start
Click Control Panel
Click Classic View
Click Power

You can adjust your computer to run more slowly, and use less power per minute, to maximize the amount of time that the battery will last, before it needs to be recharged.

Check the timing,If it is set right,your carb is running lean.
