How to change spark plug on a V star 2002 - 2002 Yamaha V Star 1100 Classic

I believe the spark plug wires are made INTO the coils..don't try

I have 2002 road star midnight. I lost completely spark on all 4 spark plugs. Before bike was running OK but sometimes on low RPM while idling would skip a firing on a at least one cylinder making spufff like sound. I put new spark plugs, and wiggled a little coil wires. Bike with new spurk plugs would not fire up at all. Checked for spark on all 4 spark plugs - no spark., not even an electrical I lost completely spark on all 4 spark plugs.

Bike with new spark plugs would not fire up at all. Checked for spark on all 4 spark plugs - no spark., not even an electrical charge going to spark plug. Went back to coils. Each coil (there 2 of them) has 2 spark plug wires and 2 ignition timing signal wires connected to them. I realized that these ignition timing wires contacts are corroded to the point they would not conduct a charge from the distributor to coil. CLEAN ALL THE TIMING WIRES Contacts on the coils. I did that and bike fired up right away and started running much better without sputtering or skipping a cylinder firing. SO DISCONNECT ALL THE COIL WIRES AND BRUSH THE CONTACTS WITH A SMALL METAL WIRE BRUSH.

Usually you know when you need sparkplugs when it starts to miss. That is it runs smooth then kinda skips, runs smooth, then skips. Spark plugs will not cause your engine to cut off completly. Could be a coil problem or a fuel system problem. I would check fuel filter or fuel pump.

just completed a plug removal and install on my '02 awd v6. if you have the time and patience it's straight forward; common sense was most helpful. to gain access to the plugs, both fore and aft, you must remove, in short, everything near to, associated with, the air intake system. common tools plus a 1/4 socket, with 8 inch extension to hold a #10 star bit. these star bolts are under the rectangular plastic plate atop the intake. once you have those out, disconnect all the wiring, carefully. lift the intake out, look for plug covers, fore and aft, ignition assembly lays atop each row of three plugs. with the hands of a surgeon, remove the ignition assembly, and by golly ye shall see your reward. easy from then on.
replaced my plugs with the iridium 'honeys'; marked improvement in starting, acceleration, smoothnes, noise, and gas mileage to the value of + 3.0%. changed out the oil with mobile1 extended performance, changed transmission fluid. took a shower. time involved, 7.0 hrs. dealer be damned,,priceless!
