    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Spark Plug problem - please help!

I have a 1983 GS550E and when I changed the spark plugs, I didn't take notice to what order the plug wires go back on.


There's no information on the wires themselves, nor any helpful information in my Clymer manual.


I know the firing order is 1-2-4-3, and there are two plug wires coming out of the left coil, going to cylinders 1 & 2, and two plug wires coming out of the right coil going to cyl 3 & 4.


I tried best I could to kinda guess, but I had some popping at first attempt. Then on the second try, it had a hard time starting, so I put the choke on very high to try to get it to start. It wouldn't turn over at first, then BOOOOOMM a super loud backfire.

Now it won't even turn over. It will crank all day, but not start.



Anyone know what order it should go back on? Like a wiring diagram or something?


Thanks for the help ](*,)
 
There should be numbered stickers on the wires under the tank, but there is a chance they're gone, so I sugges that you guess.

whatever works?

Also, look how the wires are shaped. See which shape fits each particular hole best. Hopefully you at least have the right 2 wires on each side.....
 
I don't have any of my manuals, etc. available to me now, but I do know that if you're correct about your firing order, then you're wrong about which coils fire which cylinders. Each coil fires cylinders 180 degrees apart in the firing order, which means for the firing order 1-2-4-3, one coil fires cylinders 1 and 4; the other coil fires cylinders 2 and 3.
