First of all, your bike looks rad Stratmanx.
I've been suffering the after-market blues myself. And I've been fighting modern advances like electronic ignition and LED lights, because I figure if I wanted modern advances, I'd buy a newer bike.
Having said that, my bike isn't bone-stock anyway. I have modern paint, and modern tires, and soon I'll be buying a pair of car horns, because CB750 horns are far too quiet to be useful.
I've already paid for new points and condensers, and I don't throw away money if I can help it. But next time I'll likely move to E.I. It's not going to ruin the old look of the bike, and it would be nice if my bike ran a little better.
EDIT: cb750supply.com has a set of points / condensers for $25 on sale. It's in the US, so shipping will be a tad cheaper.
