Pull the number 1 spark plug out, Turn the engine until you feel pressure on the cylinder with your finger over the hole in the head. Then get the timing mark on the crank pulley to line up with the split in the case. Pull your distributor cap off and look which way the rotor button is pointing, that will be the number one spark plug wire location. The dis. turns clockwise and run the wires 1 - 3 - 4 - 2. around the cap from that contact location.

You need 3 things for it to start: Compression, fuel and spark.

1. First and easiest thing to check for is spark. Pull one plug and connect the lead to the top. Rest the plug against the head to ground it. In your garage (or somewhere where it is somewhat dark) turn on the ignition and crank it for a few seconds while looking at the plug. You should see a bright blue spark.

2. If that checks out, and you can get a hold of a compression tester check that. We can probably assume you have sufficient compression in at least a couple of cylinders.

3. Next is gas. If it has been sitting for some time, (A) the carb passages could be gummed up. Or (B) the petcock screen could be plugged, not allowing fuel to reach the carbs. This happens to my bike about once a year. Or the floats could be out of adjustment, unlikely. With the petcock in the on position, open one of the drain screws on one of the carbs to be sure fuel is reaching them.

One last possibility is that your rectifier has gone bad. when was the last time you rode the bike?

Number one on a V6 is on the end that drives the alternator. One bank is closer to that end. So passengers side, front of car.

YOU HAVE TO REMOVE THE SEAT, TANK AND AIR BOX, THE PLUGS ARE LOCATED IN THE CYLINDER HEAD THE PLUG CAPS COMPLETELY COVER THE HOLE IN THE HEAD THE PLUG SITS IN, (TIP) DO 1 PLUG AT A TIME MAKING SURE YOU REPLACE THE CAP BEFORE YOU DO THE NEXT 1, THIS WAY YOU WONT MIX UP THE LEADS, REMEMBER THE PLUGS SIT IN A DEEP HOLE AND ARE QUITE EASILY CROSS THREADED, REFIT USING CORRECT SPANNER BY HAND, TO START WITH WHEN YOU ARE SURE THE PLUG IS IN CORRECT THEN FINNISH OFF TO THE CORRECT TIGHTNESS WITH A WRENCH

1342 or 1243

Did you have the head machined or checked for warpage?

try changing fuel

Nope
