  1. 1973 CB450 K6 Rebuild

    Engine Discussion
    I am in the process of tearing down a 1973 CB450 as part of a rebuild. I'm down to the head so far, but I wanted to ask before I forget - there are some crumbling rubber bits on the camshaft. There seems to be a groove for some kind of gasket on either side of the chain teeth for both shafts...

    Miscellaneous Discussion
    Is it possible to swap out the chain and sprockets to something lighter? Converting from 530 to 520?
  3. Newbie whose bike went down: Tank and Chain Questions

    Miscellaneous Discussion
    Hey everyone, So I'm a VERY new rider with a '72 CB450 and it recently went down on its left side. It was in 1st when it went down and it didn't fall hard because I was holding the handle bars as it went down and i wasn't actually moving all that much. When I got it back up, there seemed to be...

  5. Removed rear wheel and cleaned axle and chain, now creaking and popping!

    Tires, Wheels, and Brakes
    I am cleaning up a bike I got, 1982 CM450C and I removed the rear wheel and cleaned up all the parts. Now that I am putting it back together, the chain seems to be creaking on the axle - making an almost creeky squeaky noise. I have the chain adjusted properly to spec and I lubed it with teflon...
  6. '72 CL 450 - Putting the motor back in

    Frame, Suspension and Steering
    Today I'd like to put the motor back in to my CL450. I have the service manual (thanks to HondaTwins members for that) and it says put the motor in from the left side in. It doesn't say much more than that other than how to fit the ground cable on (do I need to sand off the powdercoat where...
  7. auto oil schproketz

    Engine Discussion
    I have a '72 or so cl 450 with the oil valve built in to the sprocket, There is a thin metal retainer that prevents the sprocket from coming off when unbolted. I believe it was missing or removed from the '71 parts bike because the sprocket and retainer came right off. What gives with the stupid...
  8. CB 350 Final Drive Change

    Tires, Wheels, and Brakes
    Hi All, I am interested in adjusting the final drive in my 73' CB350 to help lower RPMs when cruising at 45/50. I've seen a few sites offering reduced drive sprockets, or increased output sprockets. I'm wondering which is the better option for reducing RPMs at cruising speed? Also, I have done a...
  9. Next step for my CL350 engine?

    Engine Discussion
    Hi all, I'm new to this awesome forum. Lot's of good info but I still need some help. The CL350K4 didn't run when I bought it but the previous owner said that it had been running good a couple of years ago but he knew that the carbs were a mess after sitting for a while. I cleaned and rebuilt...
  10. Chain dropping / bouncing / moving when starting from stop and also shifting into 2nd

    Frame, Suspension and Steering
    So I've been hearing a strange noise for a couple weeks now and my friend who I recently rode with has confirmed it. When I start from a stop (even while in first) the chain "drops" and appears loose, but as soon as I get going it's fine. Same happens during the shift from 1st to 2nd. Between...

    Engine Discussion
    Hello. I won a Honda cb500t on ebay. I thought i would be out bid. I wasn't. The motorcycle was not running. I disassembled the whole engine. My first mistake was i didn't check and remark the timing marks before i took it apart. Missed that little detail in the manual. I think i have found the...
  12. CB400T sprocket conversion?

    Engine Discussion
    I'm going to be changing out my sprockets and chain on my 81 cb400T. On my GSXR I had a 520 conversion kit for more off the line power, is there any type of sprocket conversion kit for an old CB? Not to to stunts like I was going for on my GSXR but just for better overall performance of the bike.
