SUPERCUB: Kitaco 15T front sprocket upgrade

Today is a retake on the 15T front sprocket upgrade. I started this project last week, but the larger sprocket REQUIRES a thinner chain guide plate! I detail the entire testing procedure for the 14T and 15T benchmarks, as well as the wrenching required for this upgrade. You can skip to the bottom for the clickable time indexes to save time, or watch through the video for the entire process. I purchased the Kitaco 15T and 16T front sprockets from Webike in Japan a few weeks ago. They were out of stock on the thinner guide plates, so I took a chance on whether or not I would need it for the 15T upgrade. I found out IMMEDIATELY that it is a necessary item, so DON'T SKIP THIS PIECE if you plan to do a 15T or 16T upgrade on your Super Cub! Here are the product pages for reference: Kitaco 15T sprocket: https://japan.webike.net/products/182... Kitaco 16T sprocket: https://japan.webike.net/products/370... Kitaco Wide Chain Guide Plate: https://japan.webike.net/products/240... The upgrade is simple, and it only requires that you loosen your rear axle to slide the rear wheel forward and take the front countershaft sprocket and cover off of the bike. The increased sprocket diameter requires the use of the thinner guide plate and a bit more slack on the drive chain to fit. The process is a bit tedious, but not difficult at all (assuming that you have the tools). The list of tools required are below: - 5mm Allen/hex key wrench - 10mm socket or box/open-end wrench for shift lever/yoke - 14mm and 19mm open-end wrenches (or sockets) for the rear axle - 3/8" torque wrench - digital caliper or another measuring tool (e.g. tape measure, ruler, string) for rear axle alignment I also recommend the Motion Pro 08-0048 chain alignment tool: https://amzn.to/3wTSUmT The speedometer deviation is +2-3 mph now instead of -2 mph before, so this is a ~4-5 mph difference in indicated speed. That will affect the speedometer and perceived fuel economy without the help of a "speedo healer" like the Kitaco Speed Pulse Conversion Unit: https://japan.webike.net/products/239... I have ridden about 250 miles since this upgrade, and the motor definitely "feels" calmer. The efficiency statistics are still TBD. My last fill-up was good (136.5 mpg, which is better than my average of ~130 over the same route), especially considering the speedometer discrepancy of 2-3 mph (would make the adjusted value as ~147.5 mpg!). These numbers aren't accurate, of course, but I will monitor them and update my Fuelly stats as I progress: https://www.fuelly.com/driver/quasimo...
