Neil. With no intention to sound further 'Pompous', I have been working on bikes ALL DAY, EVERY DAY, SIX DAYS A WEEK for over twenty years. It's my full time job, career and even perverse hobby too. I run three workshops and work as a full time technician in my own BMW workshop. I contract myself out to other local dealerships of other franchises too. I have also worked for over eight years in a BMW dealership where I have been on numerous training courses and have first hand insight the the workings of BMWs technical departments.
So yeah... I do think I know what I'm talking about. That's not being pompus. I don't know many other techs who spend their free time helping out people for absolutely nothing. So shoot me !!!
I mean in no way to downplay anyone's advice on here. I've read Steptoe's advice on here myself and learned a few top tricks from him over the years. As well as others.
All technical threads on any forum are an evolution. I have been posting on forums for as long as the internet has existed. Things I wrote many years ago have been updated, corrected and improved. I don't find insult in that. And that is the real benefit of using a forum. It's a conglomeration of knowledge and experience.
There are many ways to skin a cat. Like there are a few ways to remove a cam chain tensioner from an old oil head. Like there are a few different ways to do anything in life.
I was actually sent the link to this thread by a complete stranger asking me for help on setting his end float. He asked me if he should follow it. I saw a couple of points which contradicted my training and official BMW electronic manuals so thought it prudent to update the thread. And like any forum post, you are free to take it or leave it.
As a reasonable bloke, forum aficionado and a skilled technician, I don't think the OP would be insulted whatsoever. I don't really know why you are.
