    The two carbs have been rebuilt and cleaned, been rejetted slightly, and the needle slightly shimed. Per a previous post recommendation. I checked float needles.

    Project Logs
    I recently bought a 1976 Honda cb360 that seemed to be in decent shape. It does not run but has good compression. The wiring seems to be a little messy and may need to be checked out. The first thing I am going to do is rebuild the carbs and see if that gets her running. The previous owner had...

    Fuel Supply and Carburation
    New here, bought a 1979 Honda CM400T in April. It ran, although a little rough. I've done a few things to get it running better so far. I bought Amsoil Powerfoam to spray through the carbs to clean them out. You are supposed to run the bike while spraying and then let it sit for 15 mins. While...

    Hey guys, I just recently got my 1978 CB400 on the road. I'm having issues with power at highway speeds. I have trouble accelerating past 100 kph, and have only gotten it to about 120.
