I finally got it stardet it ran fine but still had trouble firing up. the next day we took a weekend ride out of town. the bike ran fine on the trip until that evening I had a very hard time getting it started. it sounded like a timing problrm it would crank fast and then slow but would not fire up. we traliered it home wehre I tried to find the problem. the bike did start one more time and that was it I have curent at the coils both sides but no spark at the plugs.   I don't have a repair manual for this 2002 bike yet.

Dielectric Grease Therapy

Here's a fairly quick and inexpensive way of preventing electrical problems and other miscellaneous diagnostic codes on your motorcycle.

Water is a great electricity conductor. Sometimes, water can find its way into a connector producing a temporary short circuit which will then give an error code to your computers. Dielectric grease prevents water shorting at connectors. Also prevents corrosion formation on connectors.

A loose connector doesn't make a good conductor and may produce heat which can melt plugs and connectors. This is the main cause of regulator/rectifier failure.

Buy a tube of silicone dielectric grease and go through the entire wiring on your motorcycle. Work dielectric grease into each connector. All wire connectors should be serviced for best protection. Removing the tank and bodywork may be necessary in some cases, but its well worth it. Dielectric grease will get rid of the problems, or at least help prevent them.

Afterwards, you shouldn't get false error diagnostic codes just because you simply washed your pride and joy.
You may discover loose connectors that could have been troublesome if left unattended.
