In this video The Keihin carbs that were rebuilt for this bike are now reinstalled following a specific order. The tank is prepped beforehand as it needed to be cleaned out for a few days with kerosene.
Starting with the cleaning of the needles for the enrichner circuit. Im not very fond of this design by any means as compared to the Yamaha VSTAR setup. There are several quirks with this system on that note. After removing the paper towels the carb is reinserted in a rolling fashion as demonstrated and seated in the rubber manifolds. Remoil is used for all of these rubber seatings throughout the video. Attention should be noticed to the keys that hold the seals into position.
Now the enrichner needled are screwed back in carefully. They are cheap plastic so they require care in doing this , without tools.
My standard technique with the spare tank is used to purge the fuel lines using a drill bit to plug one line. The fuel that came out of the system running the electric pump was nasty. Two sessions were done 5 minutes apart until I was sure it was completely purged. At that point the fuel lines could be reconnected, the left one required special attention to ensure it didn't kink. The air hose is connected to the center of the carb.
A new filter is added into the top filter unit of the carb after all of the plastic and piping is cleaned out. Apparently this is done every 12,000 miles, I bet there are a lot of bikes with the original system, long since turned to dust, still in place.
This is followed by the linkages which are added along with the bracket. This was followed by the top manifold and then the coolant tank.
With that the bike was turned on and tested, though without an exhaust system, it can not be set up or balanced. That will have to wait for the next video.
