"Now, if you really feel that Suzuki had "all knowledge" when they put the bike together in 1987, then you should never need a verslaggy, your carb should never need tweeking and your petcock should be immortal.  Good luck with that, some like Bill still do feel that way. "

And then there is the other extreme, broke it before it left the lot on the day it was purchased...  

On sidestand, at the low line, cold, should work for most. Try it, worst case, you get an oil leak (or 10). Mine wants 2 quarts, period. On a chunk of 2x4, that shows as overfilled.

Your points given do apply to overfilling the sump by 3 quarts, but they don't apply to the extra half quart the list method includes on purpose.

The space below the oil shelf is for oil, it is the "designed oil reservoir" if you will.  The fact we use it all is nice because it allows us a very easy oil check method and a half a quart of extra reserve oil.

At three quarts overfilled you had the crank counterweight splashing through the oil pool for over half its revolution -- yup, I bet that put some nasty stress on things other than just your gaskets.  And I bet you had some continuous frothing going on sorta like a milk shake machine.

Since the list method keeps the oil out of the crank area (no splashing) I fail to see how it does any of the things you mentioned.

Newbies do all sorts of strange things to their bikes when they are new, I do love reading about them all.

As you understand more over the years then you can learn some new tricks that really do help out the engine.   And the sidestand check method comes in real handy when you get enough miles on your engine to start sipping oil all the time -- the sidestand check allows you to check oil easily every time you stop and it keeps a little more oil around to be sipped upon.

Just this past week I went to the Dragon with the boys again -- started the week out peeping over the edge of the window, finished the last run with it NOT peeping (but when I lifted the bike vertical the oil was still in the window).   So I was able to go the entire trip sipping on my extra oil and never got low at all to the old Suzuki method.

Now, gentle reader -- if I had started out with using the Suzuki method and then failed to check it every day what would I have run the risk of ????   Dead engine on the Dragon ???  Now that would suck a lot .... really.

Old list members understand relatively more and they do the things this particular bike needs to live longer/better.

REMEMBER TO DO YOUR HOT CHECK ON YOUR OIL BRAND AND BIKE AT LEAST ONCE, and if you don't understand the concepts then please don't do these sorts of advanced tricks.
