The 5-30W gives the oil a better heat range, so when you go to Florida, the engine oil keeps it's viscosity better.
The 5-W20 has a lower heat range and is great in the upper states and canada where the temperature is not as hot as Florida or Texas.
The 0-W20 is even better if your in the colder climate like Alaska so the oil is not that thick, and when you have the start the engine first thing in the morning, the oil can move quicker to the upper part of the engine. 
Best thing is no matter what oil you use, just as long as you follow the recommended oil change duration. Your going to be fine and have a long lasting engine and also make sure you warm up the engine first before running it hard to have the piston and cylinder walls expand the same time. As you run the engine hard when it's cold, the pistons expand quicker then the cylinder walls and after a few years. The pistons and cylinder walls will have to much play and you get piston slaps till the engine warms up. 
Good luck and hope this helps and the 5-W30 is more forgiving if you go over a few miles between oil changes.

It's depend on the weather condition of your area and is your motor a leaker.

10W40 should be fine,if you are live in above freezing area

10W30 for colder climate

15w-40 if your motor has a small leak AND drive in above freezing area.

2009 Hyosung GT650R head lamp went out when I was riding at night. Passby works so the bulbs are OK. Replaced them anyways just to be sure and the head light still won't come on when I start the bike....

I suspect that the alternator / regulator has failed as the battery is not big enough to run the light alone
have it check out at an accredited bike shop electrician

My Hyosung gt 650 r is not starting properly when I try to start the bike it starts for a sec n then it stops what could be the problem and I checked all the sensors with multi meter intake air control...

Hi, Anonymous nice novella if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly then stall, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or better, any readings in the 11 volt range you need to do a proper load test on the battery and replace as necessary, any readings in the 10 volt range you have a dead cell and the battery needs to be replaced.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove and inspect your air cleaner paper elements that are not oil soaked can be cleaned with a soft brush and low pressure compressed air, oil soaked elements must be replaced. Gause mesh and foam elements can be cleaned by soaking them in a container big enough to completely cover them with a solution of 1 gallon of water and 1 oz. of Dawn dishwashing liquid for small and medium size elements, for monster size double the formula and let soak for at least one hour then rinse with warm water shake off excess and let air dry, "WARNING" do not use compressed air as this will embed micro-sized dirt and road grime and destroy the mesh pattern and stretch foam elements out of shape just squeeze it like a sponge and let air dry, use a fan if you're in a hurry. When completely dry spray a very fine mist of air filter oil evenly around the whole element.
6. Remove the carburetors, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Remove fuel valve and filter disassemble and clean as necessary, remove, clean, and inspect fuel and vacuum lines and replace as necessary.
8. Replace spark plugs with new ones and check for spark.

I have oil in the coolant lines

Change and refill oil and change oil filter, refill coolant to it's level with proper mixture. Run bike on idle for 10-15 minutes, do a burst of revs and run constant rev at 5000 rpm for 20-30 secs, watch exhaust pipe smoke condition and if temperature gauge indicates overheating. Let bike cool off and check oil and coolant state. If you see milky oil, oily coolant and reservoir going empty, you may have a cracked cyl head walls. Happy hunting.

I have a 1997 900rr fireblade. I want to do an oil change and just wanted to know what kind of oil to use and how much to use?

Where do you live? That has a lot to do with choices first off...desert areas with triple digit temps... i would recommend 20w-40...cooler climates and coastal areas 10w-40 works good too! i purchase four quarts for my oil change and this includes filter change also. on most bikes people dont realize that the same oil thats cooling you engine is also cooling you transmission so oil ghanges shood be more frequent than you think, especially if you ride hard and once in awhile misshift and grind those gears. first ride the bike and get it hot then pull the drain plug this will tend to faciltate for best draining of all particulate matter. And if you bike is really old and you believe its dirty inside well just go down to autozone and grabe a can of "Sea Breeze" pour have a can in the oil system and ride it for about fifteen miles or so then drain it immediately filter too!...this cleaning gets those nasty carbon deposits off the piston and valves.
When checking oil the bike should be vertical.
I never fill to the top. always go half way...this ensures that you wont destroy the engine by overfilling. Chech again after a week to see if it needs more...after running with the new filter it will absorb some of the oil, thus taking it down a notch. Be slow on the last bottle you might only need half of it.
