As I said in the posting asking about whether you can use this type of oil in an old triple, I don't know all of the theory and the other fancy stuff that people were quoting. All I can go on is real life practical experience.
You've now read the story and seen just what the T150 did and went through in doing so. By my reckoning (and ignoring the length of time the bike more or less continually ran and ignoring the extremes of altitude it dealt with and ignoring the near freezing temperatures at one stage I rode in), if an oil can withstand 120 degrees F (I think that's just under 50 degrees C) for near on 48 hours continual running, then by my reckoning, there's something to be said for it !!
But I don't know the theory remember, so perhaps I'm just naive in my approach.
By the way, I've got lots of stories about adventures on (proper) triples. I'll dig some out and send them out to you. The trip to Russia on the Slippery Sam Replica was a good tale as was my competing in the Brit Butt Rally (the UK equivalent of the IBR - but only 36 hours this time), when I rode my 1975 T160 and came 3rd out of some 50 or so entrants. My T160 was the oldest bike by nearly 28 years I think !!
Then there is John Youngs NVT journey on the little 2 stroke.Good to see John on here.John,i am geoff the bonnie elsewhere.
