Soooo......got my '78 Bat finally running awesome. Swapped the crappy Encarwi out with a new Delortto 15.15 carb and MLM intake. It was running amazing. My son took it out for its first long-ish ride. Came back completely devastated.
Said it began to bog. Then made a really bad screeching sound coming from the engine. He had to walk it all the way home. I turned it over when he got it home and it started but, there is an AWFUL rattling sound coming from what seems to be the lower end. I'm assuming maybe main bearing(s). Or maybe threw a tooth of a gear.
Either way, he is of course devistated as we have been working on this for weeks. We finally got it running beautifully and now this happens.
Does anyone have any experience with this particular thing. I'm pretty savvy with this moped. Basically, the only thing I haven't done yet is split the crank case. Any help is appreciated!!!
Devastated father and son
