I rode like 20 hours in the past 3 days, and the bike is wonderful. I do crave a louder exhaust (mine kind of sounds like a pair of farting ducks), but I ran into a few more electrical issues that I'll need to address first...
I've been having an uneven idle situation since I got the bike running. Sometimes it would idle high, sometimes the rpms would keep dropping until it died. My mechanic friend fiddled with the carbs for like two weeks, baffled by this. But sometimes I guess the problem gets answered after a few hours of test ride, when it can't be answered idling in the shop. I was riding the bike with extra care at stops, making sure to keep the engine running, and I eventually noticed that while in neutral, the bike idled okay, and when I'd shift into 1st the bike would sometimes lurch forward a bit, and the idle would suffer. So I thought maybe all of this was the clutch cable needing adjustment, like even when I fully depressed the lever, I was still in the friction zone. So I adjusts it. Works better, but I still have intermittent idle issues.
We had replaced the regulator last week, and a multimeter showed that the thing was putting out a strong 6 amps, so I was riding all weekend under the assumption that the electrical was solid. But about 3 hours into day three, after getting food, the starter wouldn't turn over. The battery died in the midst of all my fun. After push starting, I kept the revs a little higher, hoping to charge the battery (by now I was thinking the battery was bad). Next few times I stopped, gas, pee, food, etc, it started okay, but I was killing the headlight switch before each start, so I could reserve as much power for the starter as I could. In doing all of that, I noticed that the idle was PERFECT when the headlight was switched off, and the instant I'd turn the lamp back on, the idle would drop and die without throttle manipulation.
So there is still an issue with the charging system. I headed straight home upon this realization, and on the way my headlight fuse blew! So crappy. I was only about a mile away rom home, but it was dark out and I was wearing all black. Most humbling ride ever. I was absolutely invisible.
On tuesday my mechanic is going to do something with the stator (replace it?). When I told him what had happened, he said he knew exactly what the problem is. I've been reading up on the GS forum, and relaying information to him, but he finally got on there himself. What a good friend, he is, helping me so much....
Here's a few pics from my weekend. My buddy has a 1978 GS550, and we ended up meeting a random guy with this little bobber thing.
