Yes. There have been many reports for poor quality. They are cast in Asia. So far Iíve seen a few with air leaks in the statorís threads, FMP posted a video a while back (Pinasco asked him to take it down) where the crank bearings nests were shot after a couple of thousand Kms and Iíve seen two cases where they had pores on the machined surface of the flywheel seal. I would also go for the Malossi. They have a rotary valve version as well...

25+hp engines with Pinasco master cases?
Amazing to me that these apparently expert engine builders use pinasco cases if they are problematic.

I wondered about his motors as well. Presumably he buys that many that Pinasco takes back any dodgy ones... who knows how many out of the production are not good?
I think that buying Malossi is pretty much a guarantee of quality, they are a long way ahead of the competition... they should last a good many years. I know you're not asking about the Malossi ones but with your investment to date, it might be the wise choice.

Pressure tester and a spray bottle of soapy water. I would have been lost forever without these.

Iíve tried both malossi (old one, not the VR) and Pinasco...

Hit and miss on both...

The malossi was still cast pretty badly, I feel like it was a reject off the Piaggio factory, the aluminum was rough, pitted and protrudes everywhere. And you still have to use the JB weld on the walls near the cylinder.

My Pinasco faired better, bearing surfaces seemed ok, but Iíve heard the stories of bad cases too. The aluminum is much harder, found out when porting the cases...
