I thought I would share this, I have a PE 250 B that I restored a lifetime ago that I left in my father in laws shed in NZ in hibernation - by that I mean I drowned it with WD40 and put a tarp over it 5 years ago. Anyway I was over in NZ a week ago for a few days so before I had to leave I pulled it out of the shed, shook the tank to stir up the little bit of fuel remaining and bugger me 4 kicks and it crackled into life! Honestly the only thing stopping me from taking it into a paddock was the rear tyre that lost its inflation. These bikes were great in their time and even better now. I sprayed some more WD40 over it and put it away for who knows when again - if anyone is in the North island (NZ) and might be interested in a won't die bike please PM me.
