Not Again, Dude...

I wish you'd talk to me first. I've worked on a bunch of Vstar 650s and I currently own one. Those stators and pickups are crap usually. Do it once or do again. The best are from https://ricksmotorsportelectrics.com/ and give a bit more output. The OE stuff could barely run the bike.

If you have to go into the carbs, there are two little O-rings in there under the jet standoff tubes. Remove them if they haven't turned into a tar-like substance and don't replace them. They cause all kinds of running issues by restricting the fuel flow.

Thanks for the advice, Ben. I ordered a Caltric kit from Amazon. Here's the link: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Thanks for the advice on the carb o-rings, too. I'm going to pull the carbs back out when the parts come in later today and do the valves while I have the rest of the bike apart. I thought it might be carbs to start with, so I cleaned them up first thing. When I didn't get any improvement, I consulted the interwebs and discovered the issue with the pickup coil. Apparently that's a really big failure point on these bikes. I think I may just order an extra side cover gasket and pickup coil to toss in the saddlebags, just in case I ever get stranded out on the road somewhere. Really looking the bike over carefully, it seems that this has been an ongoing problem for a while. The exhaust pipe for the rear cylinder is really heavily blued about 2/3'rds of the way back. That indicates a lot of heat, which means the cylinder wasn't firing properly, and the combustion was happening out in the pipe and not in the chamber. It was ridden like that for a while to do that kind of, not really damage, but to leave those kinds of marks on the pipe. In any event, I hope to have the bike up and running by the weekend.

Check the valves while you're at it. They can tighten up and cause bluing on the pipes. Also, the jetting could be off. If you need a shop manual, I have one in PDF format I could send you. PM me your email.
