    Now that I got your interest...opening a can of worms here.
    Synthetic oil in older yamaha 4 strokes..(sr500)
    Is this a good Idea?

    Yes Yamalube was the factory recommended way to go but it seems the formulations have changed lots over the years and am looking for better stuff..

    True, all the makers recommend their own oil for use in their bikes and thru the years oil grade's and formulations are accepted for use in older model's, but there must be even better stuff out there for the older bike to use...

    I do favor the newer full synthetic oils over the non synthetic or synth. blends as they have proven to me to be much better in my opinion. (my personal asshole opinion anyway)..
    I would use Yamalube yet it is a synth.blend in my weight requirement ,but have heard Honda is putting out some exceptionally good oils that are possibly of full synthetic..???

    I have been looking at Redline or Amsoil's full synthetics... Thoughts?... thanks

    My thought is why not? I thought about it in the sidecar but a friend in Ireland tried some full synthetic in his old BSA. I guess the synthetic he used was "watery" in comparison to his regular oil. The net result was it pissed out of everywhere. Maybe BSA mating surfaces aren't quite what we thought they were. But Japs don't leak so give it a try. Another asshole opinion.

    Do you know why the British don't make computers? They can't figure out how to make them leak oil. BSA is a British bike, of course it's going to leak oil. And Lucas invented the 3 position light switch, off, on, and flicker.

    That last article was a good read. They mention the best synthetic is usually the cheapest but don't tell you what that is.

    That must have been the top of the line Lucas switch. All the ones I ever saw were off, off and off.

    I never had any problems with Lucas stuff, except when the vibration made things fall off, guess I'm just lucky or all of you are cursed?
    I use full synthetic in all my bikes, but, I do add about 2 oz of ZDDP
    You may get clutch slip with original plates, newer clutch friction plates are made of different material (and don't have any asbestos in them)
    Anything newer than around 1995 should be OK

    I race an XT500. Several years ago I asked a Torco Oils tech what oil I should use, he recommended their synthetic blend. He didn't think I'd reap much more benefit from their fully synthetic product.
    I don't have access to Torco anymore, so now I'm using Golden Spectro Semi-synthetic, for the same reason.
    I think one of the things he mentioned was max RPM of my 500 single was well within the capabilities of the blend...
