Ok, so I fixed the turn signal wire by vulturing a good wire from the parts bike, so I can check that off my to-do list.

I'll be buying the helicoil kit to fix the stripped bolt hole in the signal generator cover. No biggie.

But the main problem is that the bike still won't turn over. I've got 13 volts on my battery, the headlight turns on, the signals work, and the starter works, but I can't get ignition. I filled the tank with new gas and set the petcock to reserve. I bought new spark plugs as the spark was really small when I pulled the plugs and tested them. But the spark on the new plugs are just as small as the original plugs. I just get a very small spark within the plug gap. Not sure how normal that is though as I never tested the spark plugs out before.

I haven't done anything to the carbs since I purchased the bike. I've been trying to handle one issue at a time and reduce the amount of variables as I proceed. I suppose pulling them apart for a good inspection and cleaning would be a good thing to check, but I wanted to get the bike running first. The carbs never had an obvious problem before so even though they may need a cleaning, I don't think they are the cause of my non start situation.

60ratrod, you suggested using starter fluid. I'll buy some today and try that out next before I move on to any carbureter work.
 
Starter fluid!! And if it starts what are you going to do? Save yourself time and money pull the carbs, I would not use the starting fluid.
 
I tried starter fluid and she started up just fine, and then she keeps running. After using starter fluid a couple of times I tried without fluid and she starts up every time without fail. WAHOO! A bunch of crap blew out of the mufflers (new from the donor bike) so perhaps there was too much crap in there that kept the whole bike from running. I don't have time to do any work on her tonight. Actually my whole week is booked, so I won't be able to do any more work until after this weekend. But I am at least happy to hear her running again. She's idling high, but I probably need to adjust the idle screw as it got knocked around a bit during this whole process. Thanks for all the help and I'll keep you all up to speed once I get time to get back in there. Thanks for all the help so far.
 
The "choke" circuit is a seperate passage from other carb circuits. There is a small hole in each fuel bowl that feeds a passage up to carb throat- this system might be restricted/plugged on one or more of your carbs causing hard cold start . Starter fluid bypasses this , but use it sparingly.
 
Will, what color was the spark? It should be a nice purplish-blue spark. I would also consider doing a full strip and dip as per the tutorial if she doesn't cold start without the starting fluid. Glad to hear you got the ole franken-girl going. If she doesn't run right the i would definitely do a strip and dip after a test ride or two.
 
60ratrod, the spark is blue, but small.

And what do you mean by a full strip and dip? Strip and dip the carbs?

While this thing is running sorta OK, do a Quick Test on charging system- see this link...

Your electrical system and connections might need attention causing a "small" spark. But I recall my bike's spark ain't what I would call big, but system starts fine.
 
Basically a full tear down and cleaning on the carbs by dipping them in everyone's favorite barryman's and usually replacing all of the o-rings.

Blue is a good color, do you get an audible pop every time a plug fires off? A nice audible pop is a good indication you have good spark. Good spark is key to a great running bike
 
Bike is running. It starts up every time without fail and without the need for starter fluid. Seems like the bike just needed to be shocked out of its comatose state, but now she's fully awake. I've taken it out a few times just around the block. When I posted earlier that I needed to adjust the idle screw I meant the throttle cable connection to the carbs. It got loosened up a bit and I haven't found the sweet spot yet.

After riding around for a bit I noticed a light tapping sound coming from the head on the front right. I'll check my valve clearances again this week and do any necessary shim replacement. Hopefully that will be it, and I can call this job finished.
