Anyone know what big bore cylinders work on the Madass
 

I picked up a 2006 Madass, and was surprised how slow it is...
I'd like to throw a big bore jug on it, but not sure which type fits it.
I haven't found any answers searching for it.

Will this one fit? It says no machining necessary, but I've also read that the case does need to be opened up.

Or can I use one of the 70-88cc ones on ebay that say they fit Sachs 50 bee and 49er?

Any help is appreciated.

Will the Lifan 125 engines on ebay fit it?

I would install a larger Lifan or Loncin engine, rather than modding your 50cc mill. They make motors as large as 140cc that will bolt in.

I'm going to put a 125 in it, not much more money than the big bore with all the parts to support it, and I'll have more power and a clutch. I don't mind losing the e-start, but do you know if the single phase stator will power the factory lighting?
