I replaced petro 2 cycle oil in my Kawasaki 500 with Amsoil. Before, it smoked and I had to wait a couple of miles after city driving to race the Honda 750s/Nortons or I had a lot of missing from fouling the plugs (and lost). After Amsoil, no smoke and all the Hondas/Nortons were history. I still use it in my chain saws. I still have an old Suzuki PE250 that has gone Barstow to Vegas twice at a 120/1 mix. The head has never been off. After I changed the ports and went to a forged dykes ring piston in my Kawasaki, I had a Corvette with huge slicks come up from Los Angeles to race me. I showed him how I could start it with one hand on the kick start. The race was a non-event. I let him start first but had pulled in front by the time I shifted to second. Amsoil rules for two cycle bikes.

On the other hand, the 300SD gets it's oil changed with petro 15-50 every 3K and with almost 450K it has very faded paint but running like new. It's semi-retired now but always ready to go.

Pierce...be honest now....the Kawi was fast but felt like it had a hinge in the middle....(owned one)..The Norton 750 ruled..! (owned one also).

I started using rotella synthetic in my 300SD, when I bought it with 240k on it about 8 or 9 years ago getting some sepage around the valve cover now, but that gasket could be up to 34 years old. I am guessing it's got close to 450k on it now. Will buy a new gasket next time I adjust the valves.

Most of the sportbike forum members run rotella synthetic, and all those motors regularly see 12,000+ rpm.

Yep! A terrible handling bike. After I did the engine mods, I fitted 16" aluminum wheels with a fat rear racing tire to both front and rear along with disc brakes. It handled better but never had the secure feeling the Nortons did. I had clip ons but never could use the clutch when racing anyone. Release your grip for an instant and you would be off the bike.  Just a quick movement of the throttle and into the next gear. I did miss a shift and put the center rod through the case. Piston broke clean in half at the piston pin. A few hand tools, a new case and it was ready to go again. The forged pistons would survive any RPM. The fat front tire along with the disc brakes bent the forks back in a quick stop. Suspension and quality frame construction was not Kawasaki's strong suit. After the mods and with the clip ons, I could carry the front end about 6 inches in the air all the way until third gear.

Still have my KX-250. It does handle well with impressive slides super easy to do in the dirt.

Food for thought. Do you know that a two cycle motorcycle's engine turns the opposite way from a Norton or Honda? It has gears instead of a chain so two cycles tend to lift the front end accelerating while the four cycles push it down.

What make learning to ride any kind of bike difficult? Your mind has to figure out on it's own the gyroscopic effect the wheels have. To turn left and anything under about five MPH, you turn the handle bars left. Over about five MPH and you turn the handle bars the opposite direction from the turn.

I won quite a few bets on that one. Easy to prove ride bike and only push on end of handlebar

I have been running the Rotella T-6 synthetic for about 3 years now in the M11. I send it in for analysis each spring, still tests like new. I have the Amsol double by pass filters also.
Being in a colder climate I like the synthetics ability to not thicken like regular oil when cold. I run it in all the cars (Mobil 1) but change it each spring or at 6000 miles.
