    Тhere is something wrong with that engine.

    Right crankcase cover is typical for "small bore" horizontals, electric starter too. But cylinder confused me. OK, it is 54 mm bore, but generally, this bore you can not see on "small bore" horizontals because spacing between cylinder studs does not allow that.

    Also, there is issue with stroke, because shaft that propels oil pump is so close to crank cheeks...

    But, what you need is to fix this engine and make few spins with your pit bike. If only piston was issue, I believe that MHJ's link will be useful to you.
    Ask me nothing - I DO NOT speak english. Really...

    I need a new electric start cover and base plate where can I find the parts? It's a under engine electric start. Both cover and base plate have metal broke off

    hi
    i have engine supposidely 125cc
    it is DJ1P54FMI

    where can i find its spec ?
    bore storoke ? CR ? Engine Oil Level (currenlty i poured 0.7L as the it gave the reading in the top range of dipstick) ? type of carb suitable for it ? (currently using pz22 with 32 pj and 85mj c clip is at the top to richen mixture).

    what could be inlet/exhaust valve clearance ?

    what are its gear ratios ?

    what is its stator specs ? how many watts it puts in each coil ? (it has 6 coil stator that is 83mm at the largest dia)

    is it full wave or half wave ?

    i bought the engine on as it is condition and installed in my bike which had initially jh90 type of engine.
