At the risk of stating the obvious, are you sure that your Odometer is in kilometers not in miles?

I am getting mileage under 25kmpl of my R15S, how I increase the mileage? I always keep speed between 50 to 60.


Hi, Kunal yes 25 KMPL is very poor you should be getting around 40 KMPL it would appear there may be something wrong with you fuel injection system and since it's brand new and still under warranty I would take it back to the dealer for repair, your main fuel tank runs 10.8 LTR your reserve is 1.2 LTR for a total of 12 LTR the following tips are low cost easy to apply/install and guaranteed to give you better gas mileage and a smoother running bike. The average motorcycle gets 56-64 KMPL. saving .2 Litre of gas could save you a 10 Kilometer walk. 125cc scooters have been known to get 185 KMPL.and more.
1. Proper tire inflation as per MFG. specifications wheels should be balanced and spokes tight.
2. Oil and coolant levels maintained at full marks, low levels produce excessive heat that causes the engine to work harder and reduces efficiency.
3. Keep extra weight to a minimum.
4. Take off from a dead stop should be smooth and easy throttle applied avoid excessive throttle snaps.
5. Smaller windshields get better KMPH than large ones, wind resistance increases as a square of the speed at which you're traveling. For example, at 112 KMPH, wind resistance is double what it is at 80 KMPH (70 squared is almost twice as much as 50 squared). That will dramatically reduce your mileage. Keep that in mind while biking.
6. Keep idle time to a bare minimum or turn off the engine.
7. Re-jet carburetor with a smaller main and mid-range jet.
8. Keep chain/belt properly adjusted.
9. Avoid quick braking, hasty acceleration, high-speed driving, try driving the speed limit and keep a constant speed.
10. On long trips use freeways or flat straight stretches of highways rather than city or rural routes avoid hills and mountains when possible.
11. Keep your engine clean, dirt and grease/oil hold in heat.
12. A full-face helmet is more aerodynamic than other types of helmets. Any other clothing that decreases your aerodynamic should be reconsidered.
13. Any unnecessary bling on your bike is going to decrease fuel efficiency.
14. Use high-quality fuel using low-quality fuel can cause sludge in your fuel injectors.
15. Keep warm up time to a minimum get off the choke ASAP.
16. Motorcycles run best when their engines are maintained, and that includes making sure the air filter is clean, the spark plugs are fresh, the fuel filter is free, and the timing/valves are adjusted.

Can't find fuel overflow hose


Hi Randy, look for a smmal thin hose coming off of the carburetor float bowl, and the usual suspects are:
1. Damaged or restricted fuel tank venting system.
2. Loose float bowl screws.
3. Damaged float bowl o-ring.
4. Improper fuel level in float bowl.
5. Worn or dirty inlet valve or seat.
6. Damaged or leaky float assembly.
7. Particle contamination in inlet fitting cavity.
8. Ethanol sludge, dirt, rust in bottom of fuel tank
Good luck and have nice day.

What is the gas mileage on this bike that holds 4.2 gallons? Also, how do i activate the reserve tank? Just bought this bike and didn't get a manual with it. How many miles can i ride before i need an...


You didn't say what size Star you had.
Mileage for the 650 is listed at 47mpg ---for the 1100 42.8mpg

The indicator on the petcock valve should have a P & R on it--- P, is primary, R is reserve. It's a simple design, with 2 different length pickups on it. So if you can't read the lettering on the valve. remove the fuel line going to the carbs. when your tank is low on fuel--- And you can determine how to set it. The pickup for the reserve gas will be on the back, or looking at it, right side of the valve.

The owners manual states to change oil every 4000 miles and filter every 8000
Personally, i change BOTH every 3000 miles. Clean oil is the key to keeping a V-twin engine happy and running for many miles. SAE 20w50 synthetic is what i use. I believe the manual calls for 20w40, which is fine for break in and while the bike is under warranty.
The choice is yours.

The Clymer service manual, is a handy tool to have. I recommend you get one. Ebay is a good place to find them along with Amazon....

I hope this helps & good luck with your Star...these are good bikes.

Dear,

Platina is a typical Bajaj bike. which is a 100cc bike and is well known for high mileage.

never over stress the engine and dont try to over load the bike.

maintain the speed of about 45-55 km/hr.

keep the bike cleen and dust free

follow the oil change schedule for better performance.

try to fill the Petrol from a particular pump everytime.

keep the bike single hand drive

remember.........bigger the gear...more the mileage

thanx

What kind of maintenance should i do to my 1989 cbr 600 f to keep it in tip top running condition


  • Change gearbox oil every 3000 miles. Change oil filter every 6000 miles. Use 10w40 motor oil. NEVER use synthetic lubricants as they can mess up the clutch.
  • Oil the chain every two weeks. Lube the control cables every oil filter change.
  • Keep the gas tank full in the cold months. This lessens internal tank rusting due to condensation in the tank. Drain the carbs when the bike will sit over the winter unless you plan on starting the bike every two weeks and letting it run for 15 minutes each time.
  • Be sure the gas valve is turned off when the bike is not in use.
  • Get a 2 amp trickle charger and charge the battery once a week for 4 hours in the winter. Be sure to keep enough water in the battery to cover the top of the plates in each cell. Know that batteries only last two years or so.
  • Check the chain tension once a month during the summer riding season.
  • Please rate my answer. Thanks.

Hi mate, what you want to do is take a dump in the petrol tank. This usually cleans the carb out with your **** and works surprisingly well.
