    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...

    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.

If any wants to know if this is something that should be done or not, um, yeah, do it.

This should be the second mod all GS riders do after direct grounding the R/R.

I didnt take a vid of it starting before, but it was NEVER this quick.

Best mod I've done to it yet, and it was a 4 dollar 10 minute job.

Do it. Do it now.

I'm lost. What was done exactly? I guess I need a diagram.

yay to Groundshock! I did this coil mod before I tore into my carbs last time. BTW, although the carbs were relatively clean, they were seriously unbalanced, and my petcock had taken a dump. Even with all that, the first time I tried to start the bike after doing this mod was just like the video. Half a crank and it fired up smooth! As was remarked in one of the threads several months ago, there have probably been countless carb tinkerings done because of the weak spark, not the carbs or their air/fuel delivery.
 
Other possible contributing items were that the carbs were cleaned up over winter, redneck style (carb cleaner sprayed in float bowls and blown clean with air, thats all), R/R direct ground, and all bullet connectors are replaced with spade connectors.

It still has a tick of a stumble and vibrates the bars at 50ish mph, but I beleive that's due to jetting/still dirty/unsynched carb issues.

Regardless of that, I picked 1.5V at the coils and it made a noticeable difference, especially starting and warming up.
 
Mine starts like that w/out the mod. I might do it anyway because I get bored easily and am running out of things to do.
 
Hey, Cliff, I sent ya an e-mail on this. :-s



For Scottsgs, here is a corrected diagram (the clutch switch is not part of the ignition circuit, it's in the starter circuit).

Hey fellas - the post titles on a search for "Coil Relay Mod" were too all over the map for me to find what I was looking for.

Can any of you guys tell me or point me to a thread that gives instructions on how to get baseline readings so I can check all these voltages before and after?

Perhaps it will start even faster. Like, before you push the button.

That's right. Better keep it neutral when you park it. Once you do the mod just entering the garage should fire it up.
