    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

Now for the problem no power on top end pulled the plugs #1 is wet 2,3,4, are ok I can pull plug wire from 1 no change in engine sound 2,3,4, and the engine dies what can I do next. There is spark on #1 maybe not hot enough spark has a orange color I jumped spark from wire to plug no change. It acts like #1 is not firing Everyone has been very helpful Thank You

you can swap the leads 1-4 and see if the "wet" plug follows
if it does = spark prob
if it does not = carb prob

if indeed #1 isnt firing the header would be cold / luke warm only and the lack of power would be noticeable across the range, not just at top end
 
You need to check you plug cap on number 1.

Had the same problem on my GS1000E. Stripped the carbs off three times thinking it was a blocked jet. Then realised that the cap was not working so changed it, now no problems.

Switch the plug cap and see if the problem follows.
Is the #1 plug new and gapped?
