Hey all,
So I'm having a rather confusing issue at the moment that only arose after installing my Pamco, mind you this was about a year ago, when I first installed it the bike would idle great, the timing was perfect, it idles way better than ever before but was a bit difficult to start, I tried to take it out on the first ride and it wouldn't rev past about 1500 RPM before it'd start to break up, badly, shuddering along with a very rich smelling exhaust (Which I could smell riding the bike) basically not firing. Did some research and we decided it must be battery related, this was further proved when I ran a hot wire directly to my ignition positive and went for a ride with zero issues and the headlight on the entire way.
Since then, I sort of solved the issue by running a wire via a relay directly to my ignition coil with two noise soak capacitors either side of the relay, every now and then, usually after short trips and lots of idling the problem would come up again but after struggling up to 100km/h the problem would be completely gone, no issues, I also haven't used the electric start for the year I've been riding it which helped greatly.
Fast forward to now, I've just got done running thicker wires through my loom as there was 2 volts of drop between the battery and the brown after the ignition, I've replaced the three white wires from the alternator to the regulator (Original regulator, still works within spec, always provided 14.4 volts at 2000 RPM even before replacing the wires, now provides it at about 1500 RPM), the green power wire from the regulator to the alternator rotor winding, the entire earth has been replaced with way overkill 25 amp wire as well as the main positive and the brown wire, I've connected the headlight up through a relay directly to the battery which has resulted in it being white instead of deep orange like it used to be.
After all that, it still spluttered on me today, this morning very mildly and as expected it went away after I hit 100km/h, but this afternoon I couldn't shake it, I checked my charging and it's good, but the battery's sitting at 12.1v's, that's according to a cheap multi metre, the strangest thing was that the indicator dash light would flicker everytime the bike spluttered and surged. I don't have my indicators wired up stock, I have a 3 wire flasher can with power, output and dash out (Rewired to suit it).
The only thing I can think of is that the earth for that wire is dropping below 0v somehow. Is there any need for the noise capacitors around the relay? Could they be the cause?
Sorry for the novel, just wanted to lay EVERYTHING out.
