Yes Monte,this forum is really helpfull!can't beat it!by the way,when i took off the twistgrip to lube it,i saw the lineup mark on the cable connector/chain,but none on the twistgrip itself?i only mention this as the Haynes manual shows how to line them up?i guess some bikes didn't have this then?Julian.

In the how to section there is an article about carb sync and it recommends to unplug one sparkplug to set the max idle speed with the airmix screw of the oposite cylinder then switch. this doesnt apply to electronic ignition does it?.

Rather than unplugging a spark plug [which can be fatal to the ICU] you can fashion an extension using a length or proper sized screw [sorry I forgot what I used] and a spare plug top lug then employing a nice long, well insulated screw driver ground each plug briefly to determine the running speed of the opposing cylinder. Probably safest to touch the blade of the screw driver to ground before moving the shank up against the exposed extension on the plug. I carry two in my roll.
Like so:

I synced the carbs Saturday rode for a while Sunday came back and with the bike still hot I hooked the manometer back up and re-tweaked here and there rode to work Monday went for a long ride got back to the house hooked it up again fine tuned again rode to work today and then a nice ride home today and it is feeling very very good it idles smoothly and I dont feel the need to tweak any longer "on the carbs". acceleration is super smooth all thru the band and I feel like I understand the ins and outs of this machine more and more everyday.

I did think of doing this also,but i;m afraid a shyed away from it!one slip and your ignition is cooked!!!iv'e learned to listen to what the bike is saying to me,and found it works a treat,J.

I was able to adjust each side for the highest by ear with both running.
It's pretty evident as you turn it with you ear fairly close to corresponding cylinder.

I dont think there is any fear of damage with the above sparkplug configuration....it's loaded no matter if you ground it or not.
As long as the spark plug stays connected to the extension it is either sparking or grounded but at no point would it be un loaded which is what would cause damage ...looks like a good setup to me...

It's a great idea,but if you wanted to adjust your mixture on one pot at a time then you would need to find a more permanent way to short out the plug on the opposite side,maybe crock clips?

I've always wondered where the 'myth' that you will damage the ICU, if you have the spark plug lead disconnected, and either turn the engine over with the starter, or run the engine in this configuration ?

The ICU is connected to the primary circuit of the coil, and there is an 'air gap' between the primary and secondary circuits in the coil, so there is no direct electrical connection between the ICU and the spark plug lead .
