Hey all. Boy, am I glad to have stumbled upon this forum! I picked up my 81 CB750F in April and have been struggling to keep it going all summer! Redid the front breaks (including replacing a piston), new battery, oil change and had the carbs cleaned professionally. Now, I still have an electrical problem (the worst kind for me, I tend to be extremely dumb when it comes to circuitry).
Let me explain...
So with the new, fully charged battery, the bike will start and run just fine...for a few days. But then, the bike will die on me, sometimes even when I'm driving it. As I'm going down the road, it'll start chugging like it's out of gas. I'll pull over as it dies on me and when I try to restart, I'll get the obvious lights dimming and maybe a turn or two before it just stops turning over for me. Or, other times, I'll go out to my bike, after it worked the last time, turn it on and everything lights up, and then when I hit the starter button, I get nothing...maybe a click if I'm lucky.
I took it to my mechanic and they told me it was because I didn't tighten the positive terminal to the battery tight enough. Okay, maybe I didn't...it could happen. But then a week later, the bike died on me again. I found a wire coming from the catelytic converter had come loose. The end was all messed up so I got out my wire cutters, cut a new end and put a brand new terminal on the end of it and plugged it back in. I spoke to my mechanic over the phone who told me that having that wire unplugged could cause the same symptoms as the loose positive terminal. He also told me that this shouldn't drain the battery. Well, the bike still didn't start and I checked the voltage on my 12v battery...it was at 11.2. So I bought a charger and that's where I sit now, charging the battery AGAIN and hoping that I can at least get my bike home so I stop racking up parking tickets.
I have a feeling that the bike will start fine tomorrow but that the same problem will arise in a few days. Anyone have any idea what this could be and where I should start looking? I'm pretty new to motorcycle maintenance, but I'm eager and want to learn! Teach me, oh wise ones!
Oh, and just for kicks, here's a pic of my bike:
