How To: Honda CRF300L/Rally Spark Plug Removal 4K

Someone asked me how easy it was to change the spark plug on a CRF300 Rally. I'd never tried so couldn't really answer. I don't have any local deep water crossings and my 16k mile service is some way off, so I don't have any immediate need, however at some point I expect I'll need to know and by then it might be too late.

This is a video of me working out how to remove the spark plug from my Honda CRF300 Rally. I think it would be the same for a CRF300L, except you don't have as much body work to remove and the fuel tank is less in the way! I've left pretty much everything in (and sped up where I could) as working out how to get to it might be useful to some folks. Skip to 07:48 for the removal bit if that's your thing.

This is the bodywork removal video I mention as I don't repeat that bit here and only start with the bodywork already removed:
