I am new here, first time Venture owner. An '84 XVZ12L. The guy I bought the bike from told me he bought it three years ago and rode it home, ran well but the fork seals were leaking badly so he removed the forks and replaced the seals. After he put it back together it would not start. He worked on it on and off for these three years and no one could make it go so he bought a different bike and sold it to me to get it out of his way. The fuse block was in the usual condition for these things so I replaced it with an ATC type but it still won't go.
When you turn the key on the warning light flashes and the display shows the oil level, fuel level, battery, and headlight warnings. Also the kickstand warning if it is down. Neutral light also on when in neutral. All of the lights also come on, including the headlight. Also the fuel pump comes on and pumps to pressure. Pushing the start button may or may not get it to crank over, once in a while it does but for the most part nothing. If it does crank there is no spark. After going through it and checking and cleaning every connection I could find there was no difference.
Yesterday while I was looking it over again I noticed that the only warning on the display was the battery one (this is most likely because the battery is an AGM and the sensor has been removed), all others were off. I hit the button and she cranked over and fired! I let it run for several minutes to warm up and then shut it off to check coolant levels etc. All looked good so I tried to start it up again,,,,,,,,,,no luck. It is back to all the above warning symbols and won't crank.
One other point which may or may not mean anything is the fuel gauge shows no fuel even though the tank is about half full which may explain the fuel warning indicator.
I am highly mechanically inclined, an electrical/mechanical tech by trade and have been riding motorcycles for over 40 years but this thing has me stumped, for the minute anyway. The biggest thing is that it never seems to be the same problem, the combination of the warning icons changes, sometimes the headlight is on and sometimes it is not, ditto with the oil warning.
Before this thing drives me to AA can someone tell me if there is a common link to all of this or do I have a whole nest of gremlins hiding in there somewhere?
