OK, GREAT news. After plugging the hot start, it's almost where it needs to be. It still needs choke to run, but it runs pretty damn smooth on it and I can even rev it up. Actually with the idle turned down a tad and choke on, it pretty much sounds normal. Super throaty, nice throttle response, etc. However, again, with choke off and even with idle turned up, the bike won't idle. It sounds like it really wants to, though, when I plop the choke off after it's going. It'll run for a second or two, then die. I have more findings, too. The TPS L-B test is good (4.25 kOhm), but I can't get the Y-B test where it needs to be, which is 4.25 * 0.13 - 0.15 kOhm = 553 - 638 ohm. The lowest I can get the resistance by rotating the TPS is to 930 ohm. Would this couple hundred ohm TPS at fully closed throttle make a difference? Thanks so much, guys, you're helping me get through this. This baby is soooo close to coming back.
