What Year is my Bike? / 2nd Simplex - No Frame Number?
« on: March 30, 2013, 08:34:16 AM »
So last summer I purchased another Simplex but need help figuring out what year it is.  Unfortunately it does not have a motor and I can't find any number on the frame like my other Simplex #14490.  From the pictures you will see that this is an early bike based on the seat spring, front forks, etc.  Interested in thoughts on this.

BTW, it was originally blue with the yellow wheels but at some point was painted rattle can black.  I can see the blue color is some places.

Frame, Tank, Seat, Controls, Etc / Front Fork Springs
« on: March 28, 2013, 08:03:54 PM »
Finally starting to dig into my Simplex by making a quick list of things I need to get the bike back on the road.  I really need help with replacement springs for my front fork. My springs are broken.  Any suggestions?

Thanks in advance

Simplexes with Non-Original Engines / Honda GC160/GC190 Question
« on: June 27, 2012, 05:26:41 PM »
Im researching the use of the GC160 as a replacement motor.  Does anyone know which specific model to go with?  Honda offers different shaft, throttle and even electric start options for the GC line.  I figured I should go with the manual throttle option, just add a return spring. Other advice?

What Year is my Bike? / 56 or 57 - Whats with the 150cc Decal
« on: June 27, 2012, 12:39:51 PM »
We know, based on the frame number 14490, that this Simplex Automatic was built in 1956 or 1957.  What confuses me is the 150cc decal on the headlight.  I have not seen another Simplex with a decal on the headlight. Is this correct for Simplex? Did Simplex launch the 150cc version at the beginning of 1957 or was it a mid year option.

Thanks

Simplexes with Non-Original Engines / Vanguard VTwin in Simplex?
« on: June 25, 2012, 11:11:46 AM »
I searched but did not find any mention of Vanguard conversions. Will a Briggs Vanguard 16HP VTwin fit in a Simplex frame without modding the frame? I know these conversions are popular with the Cushman crowd, the Cushman frames appear to have a whole lot more room.

BTW, I am new to this group and to Simplex.  I am in Minneapolis, MN

Thanks for all the great information.  Joel
