    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.

Considering eliminating the battery

I've got a '77 GS750 cafe project. The battery is dead enough I can only kick start it. Given my current financial state I can't afford a new AGM, and so I was looking at cheaper alternatives. I also want to clean up the battery box area too to give the bike a cleaner look. I've done some googling about battery eliminators but I know that some bikes accept them easier than others. Does anyone here have one installed or have some input on the subject?
 
Best to leave the dead battery in till you can get a replacement- the charging system will be happier assuming it's not already fried. Even a power wheels 12 volt battery will work, since you are kickstarting. Or a 12 volt alarm system rechargeable battery
 
I wouldn't eliminate the battery. I can't cite specifics, other than to say it was designed with a battery, and that's the way it will work best.

Yes the typical motorcycle charging system relies on the battery to moderate output power pulses so that the electrical systems does not see voltage spikes that would exist without a battery. Even if you eliminate the battery, the capacitor that would be involved will have a similar effect on smoothing the output that a battery would have.

Almost anything you do to redesign the charging system will cost more unless you have some large capacitor laying around that you can get for free. So in effect a lead acid battery is the cheapest alternative especially if you do down to 10 amp v.s. the more typical 14 amp-hr.

As Tom stated, don't run without something, else you will likely blow all your lights.
