  1. New GA Member - Hi

    Member Introductions
    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...
  2. 74 Honda CB350 Twin Idle Issue

    Miscellaneous Discussion
    Hi everyone! So I'm just going to jump right in. I've recently bought a 1970 Honda SL350 K0 that has a 74 Honda CB350 Twin motor. The bike idles great at around 1,100 just sitting in the drive way and on a quick trip around the block. But when you ride it for a longer period of time it starts...
  3. CB350 Valve(s) Opening at TDC

    Engine Discussion
    Hi, I've tried looking through this forum and couldn't find anything involving this issue for my 1971 Honda CB350 regarding the valve adjustments. This bike was previously owned by a little old lady who babied it. It had low miles and is unmolested. That being said I rebuilt the carbs...
  4. CB350 Revival

    Project Logs
    I am working on bringing life back to my CB350 after several years of sitting unused. I got this bike 13 years ago and got it running and riding well back then, rode it for about 10 years until it was stolen (and recovered) and then it has mostly been sitting since then. The ignition and wiring...

  6. Hello from Dallas

    Member Introductions
    Hello, New (to me) owner of a '73 CB350G. After riding the bike for about two weeks I decided it was time to begin tearing down and rebuilding everything, as it seems that general maintenance went by the wayside over the last 46 years. Hoping to learn a lot along the way! Shameless plug that...
  7. 1973 CB350G Ball Retainer

    Wanted Parts and Bikes
    Hello, I recently purchased a 1973 CB350G. While combing through the bike I discovered the ball retainer in the clutch lever/lifter assembly within the left crank case is missing, part # 22860-286-000. Does anyone have one for sale or know where I might find one? I've searched all over ebay...

  9. Unobtainable Part? - Frame/Rear Fender Grommet "80102-292-670"

    Frame, Suspension and Steering
    Of all the pieces of the rebuild of the CB-250 K4, one part has eluded me since the start almost 2 years ago. Grommet "80102-292-670" appears at least to me, to be unobtainable. I have tried most of the famous spares sites from David Silver Spares, Consolidated Motor Spares, Common Motor to...

  11. No power in 3nd, 4th and 5th gear

    Engine Discussion
    Hello. I hope I have posted this in the correct section. I have a 71 CB350 that I rebuilt the engine last winter after I had an oil gasket pop out and I seized the cam shaft. The cam shaft and Pamco ignition system has been replaced and the engine seemed to be running well until I took the bike...

  13. CB350 Restomod + Fitment Question

    Project Logs
    Hey guys, first time poster here. I started on this '71 CB350 a few months ago as my first ever build. Got the bike virtually all stock: Immediately tore down the bike to a rolling chassis. Used a cognito moto conversion stem to swap on a 2007 GSXR 600 front end, and here's how the bike sits...
  14. Uh boy......72 CB350

    Engine Discussion
    Well......it looks like (possibly) back to square 1. I was having a problem with the left cylinder not firing. I found that the timing on the left cylinder was off slightly. Made the adjustments and fired her up. I was getting great compression out of the left exhaust, but, the left side was ice...
  15. Hello! New to me 1971 CB350 Candy Gold, rebuilding the carbs now...

    Member Introductions
    Once the kits get here and all the guts are swapped out on the carbs, I need to get fresh tires on the thing... does anyone have suggestions? I've heard good things about Dunlops. I'd like something that could deal with a little bit of gravel road use, but mostly live on the pavement. Or maybe...
  16. Seriously.....what is this squeak 72 CB350

    Miscellaneous Discussion
    Compression test fine. Leak down test negligible. No compression = no squeak noise. What is this squeak noise and why can't I find it? I hooked up a leak down test and went through both compression and exhaust strokes and can't recreate the noise. The last time this happened I was under the...

    Frame, Suspension and Steering
    Hi All. I have recently discovered a crack in the rear part of the frame (pictures attached). it goes all the way through, but i am unable to separate it as it seems that there is something in side the frame prevents sideways movement. I took this in to a vintage motorcycle shop to get this...
  18. Whining Speedometer - 1971 CB350

    Miscellaneous Discussion
    Apologies if this is mis-labeled, but I'm having a puzzling issue with my stock speedometer. It seems to work fine, but it whines continuously while I'm riding. A few notes: 1. The whining is most noticeable at low speeds, though that could just be the only time it's not drowned out by engine...
  19. 350 engine gasket set question

    Engine Discussion
    I bought the NE Engine Gasket set for my CB350G rebuild. The package is labelled CB350K-K4 but I assumed it is common to the various 350 bikes. Most of the bits in the kit are obvious but there’s no list of contents. Hence, a couple of questions arise. . . The set includes 4 valve stem seals...
  20. Seeking update on CB350K3 tube swap for internal spring

    Frame, Suspension and Steering
    Hi. I’m Larry and new to the list. I currently have a 350f being built into a Hailwood tribute bike. My front end is from a 71 350 twin and I’m using a 66 CB77 front drum instead of the smaller 350 drum. The plan is to use the stock lower forks and I just wanted to verify if the tube swap still...
