Question about 1993 Yamaha XV 535 Virago DX
Any ideas of what could be the problem, when there is no spark in the rear cylinder. We've replaced the gas, plugs and the rear ignition coil. Would you recommend that we a) sell the piece of ***, b) take the bike to a repair shop and pay up, c) try to replace something else, like the whole ignition module or something else we've not yet come to think of?

It sounds to me like the repair shop has connected the ignition wire ( the wire going to the + side of the coil ) to the wrong switch terminal. Take a volt ohm meter and connect the ground wire to the negitive ( - ) side of the battery and expose the ignition switch terminals. With the switch in the OFF position check for volatge on all the terminals. Make note of any terminals showing a 12 volt reading. That is probably the feed line from your battery. Turn the switch to the ON or RUN position and check for a terminal other than the one which gave you a reading before. note and mark this terminal. Locate the coil. There are 2 thin ( 18 guage ) wires attached to the coil. One goes to the distributer and the other goes to the ignition switch. Isolate that wire and reattach it to the connection on the ignition switch you marked earlier...

how old is the gas it may have a lot of water or junk in it.drain the bowl on the carb and drain the fuel out of the tank, check the petcock screen inside the gas tank. also i would not spray start fluid into the plug hole, it could blow a hole in the top of your piston,spray a little right into your air cleaner or carb.good luck

First you'll need to get a jet kit from West coast star. Then you'll need to jet the carbs to run equally. This may take some trial and error. Another thing that worked on my bike was the upgraded coil kit they sell. It's almost double the voltage of the stock coils and comes with better insulated wires for a more uniform resistance. I haven't had this problem since. It'll make the cylinders fire evenly and save you from those pestiferous fouled plugs. I hope this helps.

it's not that your not gettin gas it's that the gas is not getting thru the carbs to the engine. your bike will probably start w/choke on and then die, your jets are clogged and happens to most bikes that are stored w/gas in the carbs.,,,clean them if you know how or take it to a trusted mech...good luck to you...Tim
