I gather from your handle that you are a professional, ie. you take money for servicing other ppl's scoots?
But all you got is an "OPINION"? And you're a "trained tech"? WTF does that mean? You've been to TAFE? Newsflash, TAFE trained mechanics aren't the sharpest tools in the shed.
in my limited (anecdotal) experience.
If you want to make assertions and build credibility I suggest you substantiate your assertions with facts or evidence from reputable sources. Noone gives a sh1t about some two bit mechanic's "OPINION"....
Unfortunatly you are letting yourself look a little silly. No I do not service scooters or take money for it (anymore) as I work for an Importer.
If you need proof feel free to have a look at some other post's and you can make up your own mind.
As to my credibility I think that my "Handle" speak's for it's self.
Yes I did go to Tafe.I also was trained by BMW and also have been to more service schools than you have had hot dinners, oh and there's the years working in the industry.
I tend to only give advise when know what I'm on about and not what I guess is O.K.
So if your are by chance a oil expert. I Stand corrected ( Marine oil may just work in everything?, But the truth is IT DOSE NOT)
