Free workshop printables
Sheets you can print, take to the garage, and use with no signal
Every one of these is a PDF, free, with no account, no email and no download wall. They are built for the machine in front of you rather than for a catalogue that does not cover it — record sheets, true-size gauges, diagnostic chains and checklists.

What is cited, and how firmly
Three tiers appear on these sheets, and the wording on the page always tells you which one you are reading. Regulation is quoted. A published standard is stated with the standard named. Anything that could only be traced to trade and owner-community usage is labelled as a convention, never as a specification.
- Regulation49 CFR Part 565 — Vehicle Identification Number Requirements
- VIN structure, check digit, excluded characters, model-year cycle, low-volume manufacturers
- Regulation49 CFR 567.4 — Content and location of the certification label
- Where the certification label carrying the VIN must be fitted on a motorcycle
- Regulation49 CFR 571.3 — Definitions
- The federal definition of a motorcycle, and the absence of any federal definition of a moped
- StandardISO 15 — Rolling bearings, radial bearings, boundary dimensions
- Bore, outside diameter and width of the 6000, 6200 and 6300 deep-groove series
- StandardISO 261 — ISO general purpose metric screw threads, general plan
- Coarse thread pitches for M5 to M14
- StandardDIN 933 / ISO 4014 and JIS B1180
- The two hex head across-flats conventions, and why they differ on M8 and above
- ConventionOwner community consensus
- Engine designation scheme, the P prefix, the short-case and long-case split, belt and roller marking conventions. Consistent across multiple independent owner forums and retailers, but with no standards document behind it — labelled as convention wherever it appears.
