Ex marine engineer. If you have a technical question on anything mechanical add to the comments whether its relevant to the video or not- or drop me an email. As a Technical Authority I share a common trait which is I don't guess, if I don't know the answer I will either research it or ask one on my many contacts. I am not a business, I have no money , motorbike restoration is a hobby going into retirement from oil&gas in a couple of years. I am on linkedin with the name as per my email
