I am working on a database which outlines the changes Simplex made throughout the years to help people figure out what year their bike might be. I'm scrounging back thru all the literature as well as what knowledge we've gained over the last couple years.
Once we've got a rough draft ironed out, I'll post it here for you to check out & offer additional info. Once we're happy with it I'll ask Rick to turn it into a sticky.
One thing I uncovered was in regard to front fork springs. A few weeks ago someone said their bike had 4 small springs instead of 2 long springs.....we all thought they were non-original replacements.....but I know know that the model K bike was so equipted.
