Hey!
I have Italjet Formula 50 ac from year 1996 and after changing exhaust my motor has blown up 2 times now.
Can it be exhaust or something else, because its another motors exhaust and exhaust is Doppler.
Piston kit is Malossi sport kit 70cc.
Some help or tips will be helpful.:)

Hi there, I am not an expert or anything but maybe your exhaust is not "good enough". What I mean by that is maybe the exhaust is not compatible with your current setup or maybe it's a 50cc exhaust. This could not be the problem but the possibility is there. Hope this helps :)

Nope it is 70cc exhaust
Yeah probably its because it not meant for morini engine
But original exhaust is better then aftermarket but original is for 50cc
