I should probably clarify the origin of the 25 pounds claim and explain what it comprises, for those interested in this as well as for those who are in it simply because they enjoy getting into arguments on the internet
The guys at Moto Studio are the ones who told me that that the stock wiring weighs in at around 25 pounds. They have built eight full ground up custom Guzzi V11 bikes of their own, not counting customer bikes. They know what the @#!#$# they are talking about. That said, in my comment above, I am sorry if I implied that the EFI system alone weighs 25 pounds. This thread is about improving and/or replacing the -entire- wiring harness. The 25 pounds number is for the whole stock wiring system, and I imagine they also included the handlebar switch gear in that number. Maybe even turn signals and tail light? So anyway, at least the relay blocks, fuses, many many yards of wire and plastic harness tubing, weatherpack connectors, sensors, switchgear, ignition switch, the ECU , throttle bodies, injectors, throttle body rail and linkage with the TPS and fast idle warts, fuel pump etc...
I imagine all of that does indeed add up to 25 pounds pretty quickly. That isn't what the net weight loss would be of course, since after removing all that you'd have to add back a set of carbs, an electronic ignition, an M-Unit, new switchgear. All of that stuff would be significantly less though. Both in weight and in clutter. Is it something that everyone with a V11 should do? Absolutely not! No one ever said so. But then, go through the forum and count how many posts there are on electrical problems with these bikes. Chuck just went through an ordeal with his. Then come back to me and tell me it wouldn't be worth it to rewire the bike from scratch. Hell, keep the EFI. The point is to make a simpler, more reliable electrical system.
So again, my apologies for not being clear in my previous comments, I hope this makes sense. And for those who are in it just for the joys of getting into internet pissing matches, well, I can't help there. That's between them and their therapists and/or liquor cabinets.
