In this video I identify the issue with the Vstar, or Star 650 cruiser and the known issue with ethanol that causes the engine to stutter and die directly off idle. Even if the Mikuni carbs are perfectly clean, it doesn't cause much sitting to produce this problem. We evaluate, and then remove the tank to prepare for the task. The fact is, there is little to be done to prevent this. I have tested these jets out of the bike, and with 10E gas, over time the specific jets in question will slowly continue to shrink and worsen. Experiments were done with up to 50/50 sea foam and gas mixtures but this is not really effective. Of course you can use something more reactive, say, Carb or brake cleaner, but that brings us to this video.
Now, i'm one of those folks who says, if the carb is dirty, you take it out, strip it, clean it, inspect it and reassemble it. The right way, no shortcuts!!! But I make a rare exception here. Too often Ive seen this particular setup where the carbs were superb! You could eat of of them, simply this single point of failure causing the issue time and again. As luck would have it, the bike is set up, if by design to mitigate this problem to an extent. Without having to tear up the whole bike. Just raising the tank a bit for room.
Truly, one should surmise that if after the first video and into the second removing the bowl covers reveals a horror show, then , well, this series may not be for you. This might require comprehensive work. Thats not what this series is about. It is the quickest way to resolve a known issue in the 650 carbs due to ethanol gas.
Furthermore, take notice that in this video you will see a cable rip out of the carb solenoid. A wonderful 200$ item broken 2 months after I got the bike that throws an error code to the dash. Before you go out and spend that kind of money on one of these, look at the 25c repair that I did to fix it. Also, a viewer points out that, I did not mention my penchant for hex screws. I get them at Ace hardware and often use them to replace the crappy pot metal Phillips screws you find in the Mikuni carbs. I do so at the first opportunity.
In this video I start with the rear carb Mikuni of the vstar / star 650 cruiser, carefully disassembling and then conducting an inspection. In removing the specific components we can see where the clog is, easily removed with carb cleaner and compressed air. The rubber components are re-dressed and the carb is re-assembled. For the record I shall further state, canned air is not compressed air. So please don't. And, when using the compressor, hold that part well, or it is gone.... forever....

The bike is then tested with an auxiliary gas can, and once approved, with no leaks, the bike is completely re-assembled. I wish I could tell you that I had more specific 650 videos, but I cant seem to get the thing to break.... ever...
