That is why I am trying to find out users experiences. I don't wont to get involved in the China thing. However this company made 1.1 million motorcycles last years so they must know what they are doing.

Wouldn't be surprised if they make parts for other aircraft engine manufactures. Dave

Hi,

Our experience with the Rotax:

1 (original engine) suffered from the cracked crankcase problem the earlier motors had. No help from Rotax.

2 Freak failure. We had a Rotax carb heat system fitted on the engine (original factory fit). It uses a extra assy fitted to the outside of the muffler which has circular spacer rings separating the outside of the muffler from the inside  of the heater sleeve.

One of the these ring collapsed and a piece found it's way  right through the carb system into the no.1 cylinder. Not good. We are told because of the shock to the engine we need to replace:
Crankcase and crankshaft assy including conrods.

No1 cylinder and piston.

Check gearbox.

Now the Zongshen looks attractive.

Hi All,

We have just had our second complete failure (engine right off) in our Tecnam Bravo.

Now considering a Zongshen replacement.

Has anyone had experience with this engine?

Dave
