The more I know, the less I understand - Paul Weller(?)
I always used to think a springer was the simplest thing ever. But like simple 2-stroke motorcycle engines, very basic alterations can make a big difference to the power output. Not always for the best, as far as reliability is concerned.
Nowadays, I just buy something with the power required rather than p'about & possibly ruin a nice, original gun/motorbike.
