Honda CT90 Engine Fasteners

I put this post together as reference for the length of the fasteners used in a 1972 Honda CT90 for assembling the engine cases and covers, but also for some of the fasteners used internally within the engine. Screw size convention Example: M6 x 1.00 x 20 M6 - is the diameter of the screw, which in this case is 6mm 1.00 - is the thread pitch of the screw in threads per millimeter 20 - is the length of the screw, which in this case is 20mm On a few items like pins and a washer I provide dimension in inches instead of mm. Right Side Clutch Side Cover Screws Two  M6 x 1.00 x 40 Seven  M6 x 1.00 x 20

Using a VW Lug Bolt as a Puller to Remove a Honda CT90 Generator Rotor

I had read online that the wheel lug bolt from a VW had the same thread as what is in the center of the generator rotor on a Honda CT90 and makes a good tool for removing the rotor, so I thought I would give it a try. I went on to Amazon and found a VW lug bolt and it was only $5.00, so I added it to an order I was making.  The VW lug bolt has a 14 x 1.5 mm thread which is the same as what is in the inside diameter of the generator rotor that is intended to be used for the rotor removal.
