RPM's Bottomed out on Freeway
I'm new to the forum, and looked all night for a similar issue but couldn't find one, so I'm hoping someone can help.
'98 VN750, CA Model. Carbs rebuilt about a year and 1500 miles ago (previous owner, I have the receipt though)
At about 70mph last night the bike randomly Bottomed out on RPM's. It did this twice within about 2 minutes, and I had initially thought I had throttled off a bit and not realized it, so I opened the throttle more, and a second later rpm's and everything was back to normal. About 2-3 miles later, rpm's bottomed out again, and the bike stalled out on the freeway. Thankfully I was able to get on the shoulder quickly without any traffic issues, and the bike started right back up without an issue. I let it idle for a few minutes, no issues. I proceeded the last few miles home without any other issues. I started it up again about 20 minutes later, just to let it idle, and a couple of minutes in, it bottomed out, recovered, then the engine quit 15 seconds later.
I have a little less than a quarter tank of fuel, and my first thought was maybe just bad fuel/dirt in the tank. Regardless, having stalled on the freeway I'm parking it until I can figure out what is going on. If anyone has any experience with this, links, ideas, or other questions about the bikes behavior (lights did stay on when it stalled, thankfully seeing as how it was about 9PM). Please let me know.
Much appreciated in advance.
