Alright, so that '77 XS750 that I bought... I was tinkering with it this weekend and all said and done, I got the old girl to fire up. I traced my prior electrical issues to a faulty ground wire... specifically the one running from the battery to the ground on the engine. I'm thinking the connection at the battery is to blame, but as there isn't much slack in the wire unless I re-route it, I think I should just replace it.. so my first question: What guage wire should I use to replace the ground? And is that something that would generally be easy to get?
Next question: Whoever owned this bike before me... I have no clue what this guy was thinking when he worked on it... but the airbox was in pieces, parts of it were missing... and there was no air filter. So I opted to remove the air box completely and go with the clamp on style pod filters. This left me with my new problem... the bike has a hose that ran from the back of the engine into the airbox... The shop manual states that this hose routes carbon emissions back through the carburators to be reburned. the original air box had a spot where this connected, but with the pod filters I'm stuck with leaving that hose hang loose. When I had it running, I was getting some nice smokey exhaust coming up out of this hose. Anyone got any ideas on what I can do with this? Should I just plug it or should I try to fabricate something to cycle it back into the carbs?
Final question: once again, no clue what the previous owner was thinking, but the wires to all the lights (brakelight, headlight, turn signals) have the grounds all spliced together into one ground. And the guy evidently didn't know what to do with it, so he wrapped it in electrical tape and left it hanging loose. I jury-rigged a wire to it and connected it to ground and amazingly enough, all my lights that I thought were dead came to life! so now for the question: Do I just ground this to my battery or should I run a new wire down to the engine ground or just ground it to the frame?
Thanks in advance for ya'lls help. I really appreciate it!
