"I think I have all the components to make this modification at home, even with the pickup plate already modified for the CB750. Let me know if you are interested, as I have bought a Ignitech inition instead...

Ciao!
Riccardo"

Smart move in my opinion.
I'm only old on the outside.

where did you end up with this,

I only just read your problems with dyna,  and find it really strange,

I ran dyna s with 3 ohm dyna coils with no generator and a tiny battery on my championship winning cr honda,   we stuck with this for 3 years running, and its still on the bike now.

use dyna on all my race bikes now

Ended up getting another new dyna unit and have not had any other issues. I sent my ignition and coils to dyna and they said they were are testing fine. I am running a resister from Hondaman and so far no issues.

i am afraid that it's the 20-25 minutes long races in hot weather that cook them to death :)

Any additional thoughts on keeping the longevity up? I already have the resistor pack from Hondaman to keep the 3ohm coils from doing any damage. I thought about cooling, like a vented cover might help?

could be a good idea, just tape the holes up in wet races :)

That said, i'm on my third road race bike using used GSXR box/pick up/coil combos, 10 seasons, about 60 races, 0 DNFs.... I bring an extra combo set to the races just in case, never needed it. I use the same stuff on my kz750 daily rider too. without vented covers ;)
