Background: So back in 2014 I purchased a 1979 Sears Free Spirit with the intentions of making something. After I tooled around the neighborhood for about 3 weeks stock - I got to work. The original bike was a mess, so I did not feel bad about its modification.
I always wanted to put up some pictures on Moped Army because when I started, I pretty much knew nothing about 2-strokes. I read the MA wiki’s, posts and everything else I could find for months… Anyway, I pulled some of the pictures off my phone and figured I would post them. This was my first moped and first and only build (if thats what you call it).
Modifications:
Treat Kit 70cc w/ Drilled Bing 15mm, Tomar Dry Clutch (td43) conversion with internal straight cut gears and kickstart conversion (first engine attempt)
Change to Polini RV4 water cooled, radiator, flatside tm24 with kart airbox, etc. (second and final engine attempt)
HPI Mini Rotor (The only thing I could find that would fit after I milled the area for the dry clutch)
LED Headlight converted into CEV housing with Morimoto Lens
Mike Thomas 5 star hub conversion
Trail Tech Vapor, with temp sensor, rpm
Suzuki K10 Forks with stiff springs, Brembo Caliper, Ducati brake lever
Yamaha FS1 Tank (welded front seams)
Custom Aluminum Rear Tail with Treats double brake light
Top tank Conversion with welded and supported swingarm, moved shock brace back 5 inches, frame extended about 5 inches.
Milled rear sprocket carrier to hold kart split gears
Modified BK100 exhaust to fit into RV4 head with custom muffler
YSS rear shocks
I am still trying to find my notebook with all my notes, pics, jetting, gearing, etc.
Still looking for my pedals… right now I have a bar. This moped has been sitting since late 2017, just got it back on the road over the weekend after installing a new chain tensioner.
