Yah, you do wana take the whole bike apart. Or, if you don't, you'll want to after!
Unless you're cool with the rat look.
And I think the creatures did a pink ped.. or the landsquids.. I know I've seen a picture of a pink Puch Maxi. There's also a pink Peugeot 103 in the custom photos section.
It's really not that hard to take it all apart. I find dropping the engine is easier if you drain everything and flip the bike upside down, then you can pop off all the parts without asisstance.
Just take pictures, or remember where things go, it's all pretty basic on the pinto.
Plastic bags and lables are good if your memory isn't.
