    Hey all, new to this forum and motorcycles (hell, engines too) in general.
    Back in May I had been interested in motorcycles for a couple months after a friend and I had got an old pocket bike of his running and when I saw this Honda on CL, I jumped on the opportunity.

    The ad was vague and said the engine was frozen. So I said what the hell, it'd be a great learning experience.

    The guy I got it from didn't have it long and it was just stored in his garage. He said he bought it from the original owner's grandson and that the title/plates had been lost years ago.

    I took it home later that day and got to tearing it down a couple days later.

    Some previous owner drilled old mountain bike brake lever to fit onto the clutch cable barrel.

    Uhhh, am I missing a filter screen? Cuz that's all that came out

    In an attempt at a top end rebuild a nose knows how many years ago, the old head gasket was reused and gasket maker was applied. yeahhhh....

    A few days after pulling the piston, a another head arrived. Probably gonna reuse the original valves.

    Guess I should replace this bushing.

    Looks like I'm missing some rubber bumpers of some sort to support the gas tank.

    I picked up this M14x1.5 bolt to remove the rotor. Did the job without a hitch and the bolt was $4.

    I also removed the oil filter and gave the filter a quick clean.

    Anyone have any tips on splitting the case? Don't want to spend too much on a tool i'll probably only use once.

    Check you have removed all the bolts, then check again, then get a friend to check :)


    You shouldn't need a special tool, a soft hammer to gently tap them apart. Gently!

    Quick update. The case is split and man, those old gaskets are TOUGH to remove. The gasket remover gel isn't working so I'll be trying something else tomorrow.

    Getting ready to reassemble the engine after collecting the needed parts.
    Should I use a gasket sealant for the case halves, cylinder base/head, other areas?
    If so, which would you recommend?
