I’ve had a custom for 6 years now that I got brand new. It’s been a very solid, reliable bike. For $4k it’s a chance I’d be willing to take. Obviously drain the all the old fuel and maybe be prepared to clean the injectors also. Mechanically the 1400s seem stout, the only things that I hear about are electrical gremlins. Most sound like minor issues that can be resolved if you know what to look for and how to troubleshoot. Throttle position sensor seems to be common. Knock on wood I’ve been lucky in that I haven’t had any issues. The 1400s are kinda polarizing bikes even among the guzzi crowd, you either love them or hate them. I’m a lover. Out of all the bikes I’ve owned in 40+ years of riding this bike is in my top 5, maybe top 2.
