1. I believe the "Lube Scoop" is different for each size sprocket.
From the transtar catalog:
702B Scoop, Chain Scavenging (2nd Design) (For 33T Sprocket)................................... 1 91-Up 84702B 24201870
702B Scoop, Chain Scavenging (2nd Design) (For 35T Sprocket)................................... 1 91-Up 84702C 24201869
2. The catalog only shows ONE option for a 4T65e chain.
From the Transtar catalog:
700F Chain (4T60E) (Round Pin 7/8’ Wide)............................................. ......................... 1 91-93 84700A 8660099
700F Chain (4T60E) (Exc Round Pins) (Replaces Rocker Joint Pins & D Pins) .............. 1 93-99 14700B 24202447
700F Chain (4T65E) (w/ Mouse Ear Link & D Pins) (.500” Wide) (Dual Chains).............. 1 97-Up 84700G 24206434 ← This is the ONE 4T65e option
3. No personal experience, but Ive seen others say a dual chain is better than the 7/8" chain overall.
