I have three and a half pages,front and back, in a note book of all the modifications I have done to my bike.The ones listed are just the most difficult ones.Still the mods weren't really all that difficult.Just took time,work,and head scratching.Lots of trial and error also.
I am building a day cruiser trike based off of an all stock 1990 GS500E.It's going to be for my GF and son to chase me around on.
