Note 1. 14364 is a half link (half inner half outer) and an inner link. Along with an additional master link, it extends the chain by 3 links.
Two brands of chains are used on mopeds, depending on the supply. Only the number of links is important. However, for master links and dummy links, it is recommended that you specify the brand, either YELLOW or BRAMPTON.

This took many hours learning and searching, to find the two pairs of matching illustrations. Wards gives no specs, apps or sizes of anything in the parts lists. They don’t say who makes their products and parts. All that makes it more difficult to find possible substitute parts.
All of the parts on the AR13-488 carb (bigger venturi) are the same as the AR10-429, except for: 16630 wider intake sleeve, 16628 wider main body, 16881 different diffuser (spray nozzle with both main and idle holes), 16629 wider throttle slide, 16708 top screw, and 190 unknown item.

4. Riverside-Motobecane Engines
Motobecane Mobylette Engines and Carbs 1950-1965
Wards Riverside Motobecane Engines
AV7 V The first variator “hinged” motor Motobecane ever made was on the early 1957-59 Riverside mopeds, #50165. The AV7 V motor had a Gurtner AR10-429 carburetor (not BA10-549 like Mobylette AV78 had). This motor was on Mobylette AV or AU 68 to 79, including 1957-59 AV 78, 1957-59 Riverside 14007A (because it is equivalent to AV 78). With a 10 mm carb these late 1950’s models went about 27 mph with 1.5 horsepower.
AV7 V2 (restricted intake) This variator “hinged” motor #50294 had 1.5 hp, and was on 1960-61 Riverside 14010A and 14010B. The 50294 motor had a Gurtner AR10-429 carburetor. The Riverside parts book says on page 1 that engine #50294 is on 14010A, and it replaces engine #50165, because #50165 is discontinued. With a smaller intake pipe #16673 and 10 mm carb these early 60’s mopeds went 27 mph with 1.5 horsepower.
AV7 V2 This variator “hinged” motor #50298 had 2.0 hp, and was on most 1960-64 Riversides. The 50298 motor had a Gurtner AR13-488 carburetor (like Mobylette AV88 had). This motor was on 1960-65 Mobylette AV or AU 88, including 1960-64 Riverside 14010C, 14011A, 14010, 14011 (because they are equivalent to AV 88, and the Riverside parts book says that on page 5). With a bigger intake pipe #16619 and 13 mm carb these early 1960’s models went about 35 mph with 2.0 horsepower. The rest of the 2.0 hp engine was the same as the 1.5 hp version. See the engine parts listed side by side below.
AV7 Dbe (restricted intake) The non-variator (Dimoby) “fixed” motor was a lower power version only on the rear-gas-tank model Riverside 1961-62. The AV7 Dbe motor had a Gurtner BA10-540 carburetor (like Mobylette AV43 had). This was on 1960-61 Motobecane AV43 and AV44, including the Riverside 14030 (because it is equivalent to AV43). With a small intake and a 10 mm carb this early 1960’s model went about 27 mph with 1.5 hp.
