At 4000kms you can opt to do a minor service the first thing is to dump the engine oil no matter how clean it looks you will have gunk in it change your oil filter as well. You can change the fork oil if you want but it is not needed unless it is orignal from 2005.Clean your tank out and change your fuel filter have a look at your plugs if thay have a lot of carbon change them thay are cheep. If you want to decarbon put in hot plugs and ride your bike for a good hour and then take them out do not leave them in have a look at the needle and seat in your carbi if the needle fits snug in the seat then they are fine don't forget your chain and sprockets if you can slide your chain back and forth while it is on your rear sprocket it will need replaceing have a look at the teeth make shore they are not missing or bent. I hope this help you out!

I have a pulsar 150,now my carburetor leaks oil from waste pipe,my mechanic firstly shown rust in oil tank then he change the tank ,many times clean the carburetor and change the pin.but oil leakge not...


Hi,the way it works is.....petrol gose from tank into filler pipe into carb it fills the bowl at the bottom of carb float rises and shuts off the petrol by means of a inlet valve when float pushes it shut,
so if there is petrol coming out of the over flow pipe from the carb bowl it is iver the valve is worn(can be replaced)or the float is not at the right level(to high) or float has a hole so sinks(get a small container put petrol in it and put float in if it floats its ok)the other thing is the gasket that gose between the bowl and and top part of bowl make shore its not broken,
hope this helped all the best.

Tip

How to maintain bike


Tyres: Regularly check tyre condition and air pressure. Ensure tyre pressures are maintained at manufacturer recommended levels. Check your tyres for cuts and scrapes on your tires, which could cause a blowout. Also check the tyre treads once a week and have the wheels balanced and the alignment checked if the wear is uneven. Engine Oil: Engine oil plays an important role in ensuring smooth operation and maintenance of the bike and maintaining a correct engine oil level is important. Check engine oil level regularly. Check for oil leakage. The oil thickens due to carbon deposits creating drag in the movement of engine internals. Running the bike on dirty oil will not only increase fuel consumption but also reduce the life of the engine. Air Filter: Keep the air filter clean as dusty conditions in India tend to clog up the filter in no time. Change the air filter at recommended intervals and increase the cleaning frequency in particularly dusty climes. Clutch: Should be properly adjusted and have the right amount of free play. An over tightened clutch will cause it to slip unnoticeably and increase the fuel consumption while also burning it out quickly. Engine: Regular servicing and tune-ups will keep the engine running like clockwork and reduce your petrol bills. Pay special attention to cleaning the carburetor and maintaining valve clearances. Keep carburetor clean. Every 1500 km, clean out the carburetor float chamber and other parts. Don't neglect the spark plug, ensure it is clean, the gap is set correctly or replace it if past its prime as it's the most crucial link in proper combustion. Clean spark plug regularly, preferably every 750 km for two-stroke bike and every 1,500 km for four-stroke bike. Most modern bikes require the choke to be used on cold starts as they run lean to meet emission norms as well as fuel efficiency requirements. Transmission System: A bike's chain needs regular lubrication, cleaning and adjustment. Wash the chain with paraffin, a soft brush and a piece of cloth and remove the dirt accumulated in the chain. Don't use water as it might rust the chain links. After the dirt is cleaned with the brush and paraffin wipe the chain with a clean dry cloth. Lubricate the chain links and the chain with used engine oil. Check if your bike's chain has a free play of 2-4 mm in general by moving the chain up and down in a vertical direction with your fingers. Your bike's chain must have the correct tension and free play of the rear wheel. If the tension is more the chain wont power the rear wheel smoothly during motion. If in case the chain is loose, the power delivery from the engine to the rear wheel won't be optimal and there will be loss of power due to slippage. Take the bike to your mechanic or service center and get it adjusted to the manufacturer's specifications. Never over rev your RPM going at high-speeds continuously, as it may damage your bike's engine. Never shift your bike from fifth gear to first gear instantaneously because it damages the piston rings. Cleaning: Clean the two-wheeler body surface regularly to maintain the surface finish. Before cleaning the motorcycle, ensure that the ignition switch unit, H.T. Coil and silencer are covered using plastic sheets. Avoid exposing it to direct sunlight, try parking your bike near some shade because it becomes dull if exposed to frequent sunlight. Battery: The motorcycle battery needs periodical maintenance to ensure a long and trouble free life. Top up with distilled water whenever required. Check for any leakage from battery. It should be clean and free from any leakages. In case of non-use of motorcycle, battery should be kept fully charged. Brakes: Keep both brakes properly spaced. Keeping them too tight (too urgent), or too loose (too late) is dangerous. Brakes should be tightened as per the rider's personal style and requirement. Get your bike's brake pads replaced (front) if screeching sound persists, as sometimes it happens due to lack of oil also. Change your bike's fork oil once in every 12000 kilometers. Check sprockets and replace them if necessary (wear out limit 40000 kilometers). Try and maintain a speed of 40 to 60 kilometers. Always ensure that the tax is paid and Insurance cover (Insurance policy) is within validity period. Keep Tax Receipt and Insurance policy at home and keep Photo copy with bike.

Bajaj Pulsar stops after some KMs


Hi, Surender you need to unblock the fuel tank vent line if it has one if it does not then you need to unblock the fuel cap venting system drill a small hole in the cap that will allow venting but no fuel escape or replace the fuel cap with a new one for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary transport your vehicle to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your issue. For more information about your issue please visit the website below. Good luck and have a nice day.

Why does my four wheeler keep back fireing and not starting?//


Could be air block in the petrol tube and clean the carborator and remove the dust and dirt to run the unit. Cleran the petrol tank atleast once in a year to avoid dust formation at the bottom of the fuel tank. Adjust the gap in the spark plug to standard specification to avoid back fireing.

Honda Unicorn, after running for some kms, does not accelerate


Rust in the tank is not good. Put a liquid fuel tank liner in it to seal off the rust for good. Clean the carb and install an in-line fuel filter. Where are you getting gas? You may be putting bad gas in the tank, gas with a bit of water in it.

Can I get a “very helpful” rating on this answer? And it doesn’t cost anything extra!

Dear Pravin,

Always check for the oil level before you start for the first time during the day. If you can just shake the bike you'll know how thick or light the oil is. The more lighter, you'll have to change faster. Also check for color. Oil can be maroon/red/dark green/etc. depending on brand. If its really black, change it fast. Dont do top ups. Better drain the entire oil and fill fresh oil.

The oil also acts as a lubricant to the gearbox. If you feel gear shifting is becoming too slippery or too tough, check for the viscousity, as said earlier. Slipping gear shift can also be due to a loose chain. So check for that too.

By the time you finish 1500 kms or 2000kms, its better to change the oil.

It is better to use Castrol Power1 for Pulsar. It prevents overheating and also keeps the engine and gearbox smooth. It also maintains viscousity at high temperatures for better lubrication.

My experience:

I used to put servo and every 900-1000 kms i had to change oil. Now with Castrol, I change only between 1500-2000kms. I'm getting mileage between 50 and 55kms for a litre of unleaded petrol.

Hope this helps in solving your problem.

Have a nice time riding pulsar.

Always wear helmet and drive safely.

Kawasaki ZZR400 Won''t start, Looses power in top Gear


Hi and welcome to FixYa,

Initially, would suggest:
  • a thorough cleanup job on the carbs;
  • inspect, clean the rubber couplings from carbs to intake manifold;
  • inspect tighten coupling clamps;
  • ensure no vacuum leak when re-assembling;
  • inspect, check, ensure air intake box seating to the carbs. Very important, there should be no air leak. All air must pass through the cleaner/filter;
  • check/clean tank, including fuel valve control and built-in fuel filter;
  • use PRIM instead of ON on the fuel valve control.
And the "carborator sleeves" will only slide up when there is sufficient vacuum (engine running) and the throttle is turned.

Good luck and Thank you for using FixYa. Happy Holidays.

Is decarbonising is necessary


Hi! With modern fuels and oils there really shouldn't be any need to de-carbonise.(Unlees Mixture is incorrect?) If you are really concerned then try a quality fuel additive, read fully the directions for use and Bingo job's a good-un.
Fork oil change, is there a reason? are the forks weak? any seapage? if not leave well alone as you may open a Hornets Nest.
Telescopic forks/dampers use very light oil for suspension, too much will blow oil seals, so if you are determined to change the fluid then make sure the correct viscosity is used and critically the correct amount/quantity. Cleanliness is of the utmost!
Good Luck!
