haha, three head bolts... if only we had four so it would take more time to take off the cylinder head and be confused by that special way the fourth bolt comes off. I also wish my clutch and transmission were all packed in with the engine.
All fun aside, vespa engines are really a trip once you take them apart and realize how well designed everything is. People joke about the subframe and the rear transmission, but Vespas are well designed and were built to be ridden stock. I think this is why Puch followers hate them so much. It takes more skill and time to do it right. You can't just slap an estoril and polini on it and go. :D
I like mopeds, though. It is all good.
