The green unit delays the spark for a revolution or two to help protect the sprag clutch. I suppose that in theory it could make a KS more difficult
I thought the spark delay was a separate small black box that was plugged INTO the TCI unit. Isn't that why the third plug was added to the original black TCI box, which originally had only two plugs, to plug the delay box into?
I didn't think the delay was internal to the TCI box. On my '08 it was a small black box in the left side case that I unplugged from the TCI unit & removed from the bike very early on. Removing it made no difference at all to the kick starting or electric starting in the early days of my life with this bike. And the Green box still retains the third plug for the delay box. If the delay was internal to the TCI unit, why does the green unit still have the third plug (for the delay box to plug into)?
I believe most of my kick start problems now are carb & timing related & maybe a little also from the Ace head mods which have kicked my comp ratio up to 9.8:1 & changed the way the bike sucks & flows air.
It just might be that my kick stroke is just not powerful enough now (I'm very much weaker now than even 5 years ago & I only weigh 140 pounds) to fire this sucker off when cold. When warm it's a one or two kick starter.
Yesterday (as I've said) I kicked it to life 6 or 7 times after various cooling times (up to 3 hours) with no problem after changing back to the old black box. It "seemed" to start more easily with just one smooth kick than before, but that might all be in my head. It was VERY hard to avoid kickback with the green box. Not so with the black.
I know it's because of all the mods that I'm having this kick start problem (& I accept this all, it's what I wanted) because previously with the CV carb, stock head, stock intake, black OR green TCI, it kick started any time, anywhere, hot or cold without a moment's hesitation or drama.
I just need more time to work it out. We'll see later this morning how the black box works out when the bike is cold. I have NOT been able to kick start it cold with ANY combination of tuning since the mods so if it kick starts today cold with the black TCI what are we to think?
