  1. Engine Discussion
    Hi all, (first post on here so I hope I am doing this right) A little history first: I bought a 1970 Honda CB350 a year ago in pieces. Put it all together and found out it had a few engine issues and the transmission worked except I could never get it into second gear. It would always grind...
  2. Engine Discussion
    Hi all. After doing some research. I believe that I replaced a skinny camshaft with a fat camshaft for my 1971 cb350. (Purchased from eBay with correct PN 🤷‍♂️). My bike has been overheating. I assume due to the difference in lobe length/size this would cause the valves to open and close out of...

    The stock mufflers on my CB350 have rusted out as most do. I’m looking for a new set that look similar to stock, I was wondering if anyone has any recommendations, preferably on the cheaper end but definitely want something quality.
  6. Mechanical Issues
    So I got in a cl350 project recently. It cranked up well with the starter but wouldnt idle very good or run consistently so I took the carbs off went through those and clean them and replaced anything that needed replacing. I also adjusted the clutch, ignition timing and valve height since I had...
  7. Tires, Wheels, and Brakes
    Getting ready to remove these cush bushings and was wondering if anyone has done this recently. Found a few methods online like drilling out or threading the center. All methods look like a pain so wanted to see if anyone knows or discovered any new ways.
  8. Engine Discussion
    My scrambler project hit a little snag in that I just noticed that my lower crankcase has damage in two spots. One spot is the formed lip where the kickstarter return spring hooks and the other is a tubular part of the casting where a bolt connects the upper crankcase and the lower crankcase...
  9. Engine Discussion
    Hello all, Just recently bought a 1970 cb350 twin that wasn't running. It was pretty easy to get running, and it idles fairly well, however, I'm noticing some problems/differences between how each cylinder is running. Here is a list of what I've done to it so far: Replaced the intake boots...

  11. Engine Discussion
    Hello everyone, I own a 1970 cb350 twin and the previous owner fit it with a 2-1 exhaust that unfortunately covers the oil drain plug. When I was disassembling the exhaust manifold/collar assembly to access the drain plug, I must have not been paying close enough attention (I know, rookie...

  17. Engine Discussion
    Greetings to all, I'm new here so hopefully I'm posting this in the correct section.. I purchased a 1971 cb350 in pretty darn good condition about 6 months ago. It runs great, starts on first kick every time, and I have had no issues so far. I bought it from someone who seemed to take pretty...
  18. Mechanical Issues
    Hello, this is my first post after going through tons of forums helping me fix up my cb350, but I have hit a barrier and cannot seem to find anything on it. So, I bought a '71 cb350 which ran but not well and would require me to fight with it. It would start after fighting it, but struggling...
