When I first started to dive into the carbs on my 1985 Honda VF500F Interceptor, there were a few things I was nervous about. I didn't expect them to be super gunky inside, because although I had an intermittent stalling issue, the bike did truthfully run pretty smoothly when it was actually running.
Like, very smoothly. Not stumbling, not unpleasant in any way. Very nice.
It's just that I wanted it to stay running that nicely all the time, you know? And I didn't know when the carbs had last been tended to. The previous owner said they'd cleaned them, but some other questionable decisions they'd evidently made became clearer as we dove deeper into the bike. And they also made me realize I'd feel a lot better if I knew for sure.
