    Yamaha yw100 engine swap with yw125?

    I've got a Beewee 100 and have done a number of mods on it, mostely aesthetics. However now I'm looking into doing an engine swap with a big bore kit from jiangwayne.com to up the engine to ~130cc.

    Another idea I've thought of is just swapping the engine from the yw125 or corresponding big bore kits to get it to ~200cc onto the yw100 chassis.

     

    So my question is, has anyone, or does anyone know if the engine from the yw125 would fit onto the yw100 chassis?

    Because if it does, then I'll be able to get an aftermarket big bore kit installed to double the original engine capacity for huge power gains.

    Hi

    There is a member here who owns a Zuma and he has done everything to it. 

    I hope he sees your post because he could answer your question hopefully he will see it soon.

    If not someone will theres alot of really clever people here.

    Hopefully. It'd be interesting to find out if it was possible because going from a 100cc carby fed single cylinder engine to a +180cc FI engine sounds like there would also be a lot of electronic work to do.

    Might aswell just get yw125 and avoid that though.

    The YW100 and YW125 are very different scooters with the likelihood of an engine swap being near impossible.

    The frame would be very different and cables and electricals would be a nightmare to sort out.

    Even with an unlimited budget and an expert doing the work, any conversion would probably fail.

    Damn, I knew that would be the case. Oh well just a pipe dream anyway but would be awesome to see attempted.

    Thanks guys.
