    Dear Honda Twins Community, Chris Saxby who many of you may already know from this Forum has been providing valuable guidance over the lockdown period on my restoration of a 1966 Black Bomber. During this time I have also acquired a 1968 'Red' Ken Ives Bomber with its original Leicester Plate...
  3. Tires, Wheels, and Brakes
    Greetings, New to the world of vintage Hondas and I'm looking to pick some of your guys' brains about refurbishing and repair. To start, I've got a CB450 K6 that had a rear drum brake that was completely seized. I was trying to be careful with removing it, but the inner rim of the cover that...
  4. Bikes For Sale
    Hey everyone, I'm looking to sell my CB450. Just too many toys in the garage and she really needs a new home with someone who'll actually take her out for some rides around town. Currently listed on Facebook Marketplace. I'm in the Twin Cities if you'd like to meetup and see her in person. I'm...
  5. Fuel Supply and Carburation
    So I bought a 1982 CB450SC that ran like absolute garbage. One plug fouled out and the other insanely lean after a ride around the block. A little bit of inspection found gummed-up vacuum pistons and a plugged idle jet on the left carb. I tore everything apart and cleaned off the molasses and...

    Hi all! I have my dad's 1986 Honda CB450SC I am attempting to get going again for him. Replaced the battery and now working on it not wanting to start. I think I found some answers already searching around. I am going to try disassembling the push start housing and cleaning the contacts and...
  8. Tires, Wheels, and Brakes
    Hello, I have a '73 CB450, currently trying to rebuild the front disc brake caliper. The issue is the piston–for the life of me I can't get it back in there. I've tried (per other posts) • obsessively cleaning the channel that the seal sits in, to ensure there's no debris • lubing the...

  10. Engine Discussion
    Two years ago my friend and I rebuilt my 70’ CB450 engine with the bottom end of 68’ CL450. It was riding pretty well for about a year (for the exception of some power loss). But about a year ago I went for a ride and while riding in 5th on the highway, the whole bike jerked like the clutch...
  11. Parts For Sale
    I have a bunch of parts leftover from a 1974 CB450 build, started off with 3 bikes so lots of leftovers. Would be great to help someone local who needs bits and pieces to complete something they are working on. Some parts have a value but others I’d be willing to unload for next to nothing...
  12. Tires, Wheels, and Brakes
    Just replaced the shoes for my rear brake and got the wheel installed back on the bike. After taking the bike off the jack, I noticed that the rear brake pedal had way too much range (~3 inches), so I just turned the adjustment bolt clockwise (in), which solved this problem. The range is now...

    Hi everyone. I'm from Santa Cruz CA and have been working on vintage Honda bikes for friends for a few years but I am a vintage Volkswagen mechanic for a living. I have finally got an old Honda of my own, an '82 CM450E. I'm joining this forum because on my bike I have some custom things that...
  14. Tires, Wheels, and Brakes
    Hi, '67 CB450K0 here, replacing my rear brake shoes and rear wheel bearings. Figured they're due for some work. Just have two questions about this. 1) I noticed there seems to be some grease that you can see leaking out of the bearing in one picture and onto the removed brake housing in the...

    Hi Everyone, I'm a 30M and have been around motorcycles since I was a kid. I grew up riding dirt bikes on our farm and got my first street motorcycle when I was 20 (1986 Yamaha Radian). My current primary motorcycle is a 2013 Triumph Street Triple R , which I absolutely love, but it is not...
  16. Engine Discussion
    Several months ago, I sent the top and bottom case for my '73 CB450 off to be vapor blasted (shout out to RestoCycle). The results are great and all my other parts have now arrived. However, while inspecting everything before beginning assembly I noticed something. I'm sure that the blaster...

    Hi all, My bomber needs a new crankshaft, and it seems to be a huge pita to find! I posted on the looking for parts sub already, but I was wondering if anyone here might know where i could try to look for one, as ebay seems to be fairly thin right now. If only the later crankshaft could fit my...

    Hi all, I am in need of a 1966 cb450 k0 (black bomber) crankshaft assembly, which seems to be a pita to find:eek: only one I found so far was running $1,375 on ebay. A bit too much for me! Hoping someone here might have one or know someone or even where I could be looking for one! Many thanks, B

    Have a 1969 K1 (blue, looks same as 1968), a 1972 K5 in red, both restored (latter has very low mileage and mainly needed cosmetic, electrical and carb work ) and a 1976 CB500T which has low miles and needed no restoration, just a new battery and starter clutch. It does not vibrate! Handles...
  20. Electrical Issues
    Bought this bike awhile back with a seized engine. Swapped it out with and engine out of a cl but swapped the rotor and stator our of the cb. I’m lost on how to hook up all the engine wires. Sorry new to vintage motorcycles.
