Hi guys. Your answer Walt is no. You won't be reseating worn rings or
pistons or cylinder walls with oil or any additive. Additives will never
replace or reform the metal (pistons,rings, cylinder wall) that has been
deformed or worn away. The idea of sticking piston rings is quite far
fetched for a modern day motorcycle engine. If your rings are sticking then
you would be pumping oil on a consistent basis (cold starting, warm
starting,idling, running at low revs, running at med revs, running at high
revs,erratic oil consumption,people following you on their motorcycles would
have some pretty tails to tell you.......)& the power of your engine will be
way way down. You should really notice the lack of power.What RSRBOB is
trying to do is help people live with this annoying but completely normal
symptom. You can try to prolong the life of an ailing powerplant but you
can't avoid the inevitable. Engines are designed to wear out & they can't do
anything about it. RSRBOB's theory is sound. It brings to mind an experiment
I did many many moons ago. I had a 4 cylinder 4 stroke motorcycle that would
wear cam chains & tensioners prematurely. After some 20 000km or so it
started to consume rather large amounts of oil as well. Well when I finally
had enough I tried the thicker oil theory. The oil that actually made a
difference was 80W 90 gear oil. My experiment consisted of a combination of
street riding & yes race track time. On the street I found cold starting
took a few extra spins of the starter but the engine became extremely quiet
& the oil consumption was down to a trickle. On the race track the engine
performed flawlessly & my racing buddy finished the race quite respectively
I may add. I wouldn't recommend anyone trying this on their GTS though. But
the theory has been tried & it works. FYI, I sold that darn thing soon after
my experiment was done so the after effects of those experiments is unknown
to me. Speculation would have that I did more harm than good to whatever
life that engine had left. Be good. Ride safe. Peter Piazza.
