Thank you all~ I got the idea now haha great to know till where I could push my bike to have little more fun..
Well... you guys might not believe this,,, but When i got my last oil change.. I pushed the first gear about 35miles on a hill and oil cover (right side of my engine) explode and it were all over my feet so since that I was kinda worried...
Any idea what happened there??

Generally, anytime a piece of an engine breaks and oil gushes out, being
Concerned
is a Really reasonable feeling.
Did the engine survive?
The dealership should pay for another shop to check it out and replace it or warranty it for a t least twenty thousand miles. Against oil starvation type problems.
I'm still wondering HOW anyone could possibly think the filter looks right bakkerds
And
HOW do you actually accomplish it?

This is the third
Professional oil change
I can remember that they put it in backwards..

At 8000 rpm you might think you not floating the valves but you are about 2 rpm from finding out what happens when it does,that strange metallic sound right before it sputters to the side of the road if your lucky , or it just locks up ! With the close proximity of the exhaust port to the tiny valves & guides and lack of liquid cooling it a very fine line with heat ,that exhaust valve slows for just a millisecond it's all over. Remember this is a cruiser engine not the old race worthy SR500 or a modern liquid cooled thumper. Best off trying to build it with a wide midrange power band rather than a high revving time bomb.

I rarely open it up to WFO, but if I do, it's in fifth.. I just lay into it pretty good, about 80% throttle and change gears when I feel the acceleration peak.

If you're trying to pass someone, back away from them and accelerate at them, timing your
I NEED to change lanes or hit the brakes
Moment with the gap in oncoming traffic.
If you're even Close to going on reserve, just flip the petcock before you start getting set up.
Don't ask, okay?

Just a thought but if you ever look at a dyno run you'll see that torque and horsepower lines always cross at 5250 rpm ,that's about 80 mph on a mostly stock S-40, that means any further speed is a extreme uphill battle ,so to me a steady speed on the highway of 60-75 (depending on speed limit) is as hard as I push my bike without worry about damage,I reserve wide open throttle for passing only.

That's because hp = torque * RPM / 5252 (not 5250)

Reply #40 - 01/03/17 at 22:05:27 Right Kris! sorry I was 2 rpm off! but even though hp is still rising torque is dropping off even faster. where it might take 20hp to get you to 75 it will take 20 more to get you to 100 ,hence the "uphill climb'.
