  1. Manuals and Technical Documents
    Hi folks, I don't think this inconsistency in the shop manual has been identified quite as directly as this before, though I am very surprised by this as many many people must have been very confused over the years and talked about it before, and its more likely my lousy searching - in which...

    I’ve included some photos of an oil leak on the cylinder head side cover (I believe). What do y’all think it means? What’s the best action? Thanks for the help, this is my first post besides my intro.
  3. Fuel Supply and Carburation
    Hello, First post here. If the answer to my question is somewhere else, just point me in the right direction. I have searched, but can't find it. I am looking to remove the airbox on my 1981 CM400c and put pod filters on. I have read a lot about how to do that properly. The only question I...

    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...

I recently replaced the old cylinder head (which had a stripped spark plug port) with another used but unstripped cylinder head.

  7. Tune Up
    Hello all, Currently in the process of doing up a 1984 CM125C twin. As i understand it has the same bottom end as the CD engine and a similar top end to the CB125T, My question however should be non-model specific! At the moment i have a 142cc big bore cylinder and piston kit on order for the...

    Wrapping up a cam chain replacement on my 73 CB450 and realized one of the guide pin cutouts in the cylinder head gasket isnt big enough. Looking around at dime city and 4into1, im pretty sure this is the correct commercially available gasket. Can I cut the hole bigger or am I missing something...

    So I found rusted valves in the head of my motor so I immediately decided to find a "rebuild kit" and plan out the process but I cant seem to find parts through obvious google searches which leads me to believe we have to search for parts by spec rather than by application? I haven't found...
