I would say get the engine nice and hot before you try remove the plugs but that ain't gonna happen.
I hope for your sake that the threads in that last plug are ok and it hasn't been bodged.
Just to update.
I purchased a pair of Five Ten Freeriders and i'm looking at this jacket: https://www.evanscycles.com/madison-addict-softshell-jacket-EV247972
My boss has a P85D and in insane mode its errrr insane. You pretty much can't move when its accelerating.
Id happily have an electric car for my daily commute with something fun for the weekends.
I'm gonna order a pair of Five Ten freeriders and was wondering how people have found the sizing?
Is it about right or should i go a size bigger/smaller than my normal shoe size?
That looks errr knackered hah. Is stuff like the broken 'rock-ola' banner at the top easy to get replacements for?
I bet you could fairly easily replace all the internals with a raspberry pi or something.
The video suggested the brass keys come in various sizes. I wonder if they choose the 'best fit' when assembling them.
