    Hi, I am new to this site and also kind of new to 'bike mechanics'. Just bought a project bike - 1989 Honda CB400t/hawk. In the videos it ran great but the prev owner informed me that the Kickstart wasn't returning. So I opened the Kickstart case cover and with it open the Kickstart returns...

    Last September I bought a 'barn find' Hawk with low miles and a lot of rust and neglect. I go the bike running by the end of October and got a few short rides in before winter set in here in western MA. Due to a combination of rust in the fuel tank and carburetor issues, it wasn't running...

    Hello, I've been having trouble removing the cylinder. I've done as the manual says and have removed what needs to be removed. The cylinder moves freely by about 4mm until it stops. It feels as though as though it's coming into contact with another piece of metal, but looking at diagrams and...

    So, this is a update to my previous thread since I guess no one knew what was going on. After cleaning the carbs a million times, putting a carb kit in, new air cut off valves, new floats, it looks like I'm done with the carbs, kind of. Right now, I tested it out by letting it idle, idled...

    Oy, this old Hawk is my first bike. She has some faded clear coat and just over 15k miles on the odo but seems to be quite peppy. If there are any "obvious" crash course threads to look into on typical things to be aware of or fix please do! Thank you! John N

    Hello everyone, I was hoping you all might be able to give me some help. I'm trying to replace the rear sprocket on my '78 Hawk TII. However, I've noticed that all of the replacement sprockets are all just a sprocket unto themselves. The stock sprocket has a back plate of sorts that is riveted...

Once I do that I plan on modifying it into a cafe racer...
