This is really interesting. The Morini engine has a really bad reputation here. I don't know if the Italian aluminium is just incompatible with the harsh winters here, or if it's all just confirmation bias.
One problem is also the fact that a lot of the Tunturis seems to be in the hands of a very few, with no one willing to sell any intact parts.
Finnish forums are notorious for trolls and people behaving badly..so in addition to crappy overpriced parts you get a slew of insults. Often all in capital letters followed by a few lines of exclamation marks..
I really like the looks of the E50, too..and with an abundance of parts available this seems like a good project.
Edit: I also chose the E50 because I probably lack the skills and knowledge to properly build/repair the Morini engine. I don't feel confident in modding parts meant for other mopeds/scooters to fit my moped, so I'm kind of trying to compromise. This way I will learn something new, but it won't be too difficult.
