Yes, but the plug was very sooty. I do think this may have more to do with the age of the plug and how eroded it is. I will recheck it when I have turned up the coil retainers and fit them.

IOW I don't know how you will "turn" such a cap seal ... on something like a lathe.
Perhaps if you cut it to a rectangular profile, drilled the center and then mounted and turned down the lower section, that might work?
Very interested in what you end up with and you you got it there.
Same for what your process it to machine or turn Urethane

i am interested to do this mod as my caps and plugs must be quite old now
only thing
how do you wire it ?
there are 3 wires going to the oem coil and 3 from the new stickcoil offcourse with the white plug on, so i am geussing just cut and solder but wich color go to what ?
also with this you can modify a quickshift from another bike.... must be a standalone unit with only ignition cut off but still quite a easy job...

If you have a look at the head design and how the OEM plugs fit in the hole.. I think you'll see, its not a round rubber retainer that is bets suited for the task. But a retainer that is round at the lower point to seal and steady the cap on plug, oblong rectangular shape at the top to fully seal the spark plug well off from debris and weather.

My partner has just had surgery and is high need at the moment so she take priority. But for the last week its has been very wet here. Everyday to and from work has been heavy rain. Bicycle tubes work as the bike has not missed a beat.

My plan is to make a tapered tube to slip over the top. It shouldnt need to rectangular piece if it fits right. Will detail it when I make it.

That other thread linked is the best collection of info on the subject.
I think reusing the OEM boot is the best way to seal out water/debris
One of my pics in that thread shows the detailed carving I did to get a really good seal on the stick coil. I also used some silicone as shows in Pic #2 of mine

You won't get any more power if you don't increase gap with a stronger spark. Coil on reduces the resistance in the line. That's the advantage. V=IR. When your V is 50,000 Volts, your I goes up quite quickly even when you only dropped resistance by 0.01 Ohms. If you are doing the coil on mod, increase plug gap slightly. Maybe 5-10%.

Yes, there was someone (I believe it was Tweety on the UK vtr1000.org site. A search will confirm) who dyno'd thier stock coils and then tested the more modern Coil On Plug (COP mod) a.k.a. Stick Coils, back to back to back. There was actually a 2hp difference. Why? I am 99% positive it was because his stock coils were the originals from 1998 with a crap load of miles/use on them.
A lot of people, myself included, do this mod, because thier stock coils are old and instead of buying new stock coils, why not upgrade? Less weight (however little), less parts, less wires. And if you do it right, you buy a set of four coils with harness off eBay, sell the other two coils on here and the mod will be almost free.
