Measuring gauges you can print at actual size
Part numbers on Chinese powersports machines cannot be reliably cross-referenced, so the working method is to measure what you have and match the dimension. These sheets turn a printer into a set of reference gauges.
Variator roller sizing card
True-size circles for every common roller diameter and a width scale. Drop a roller on the sheet and read the size off directly.
Open and print →CVT belt profile gauge
Actual-size belt cross-sections by top width and included angle, plus a wear check. For belts whose printed markings have worn away.
Open and print →Carburettor spigot and bore gauge
Nested true-size rings for intake spigot outside diameters and carburettor bores, so you can size a replacement without a bore gauge.
Open and print →Wheel bolt pattern overlay
Bolt-circle overlays at real pitch-circle diameters. Line the centre cross up with the hub and see which pattern matches.

On a Japanese machine you look up a part number. On these machines that method fails, because assemblers change component suppliers between production runs without changing any published designation. Two machines with the same badge, year and engine family can carry different belts.
The specialist retailers say so themselves — VMC Chinese Parts tells its own customers to compare the details against the part already in the machine and choose the closest measurements. These sheets exist to make that comparison possible without buying a set of bore gauges.
What these gauges are not
They are measuring aids. A dimension that matches tells you a part is a candidate, not that it fits — clearance, offset, spline count and electrical specification all still matter. The full version of that warning.
They are free, unwatermarked, and there is no account to create. Print them, photocopy them, stick them on a workshop wall.
