Royal Enfield Bullet 4 speed gearbox - converting to close ratio, the whole process step by step.

Apologies for the repeat showing of the first couple of minutes, but they tie in with the rest of the material in this compilation, where I try to discuss and demonstrate aspects of 'how to' strip the 4 speed R.E. Bullet gearbox and fit a close ratio conversion - and a wide ratio conversion would be fitted in the same manner, for that matter.
I don't go into great depth about stripping and rebuilding the gearbox itself this time, as I already have video material discussing that, but most of what needs to be done is covered here and might be of some use to some wishing to carry out this conversion.
