SOURCE: Petrol

please this is not a matter of paying extra money to the goverment. Xtra premium(45.04) at just 1.5 rupee a litre more than normal petrol(43.54) gives back double ur investment in terms of better fuel efficiency and a cleaner engine. Even my vehicles mileage increased drastically from (41 to 55). also two wheeler owners like us wouldn't feel the price diff. (on 6-7 ltrs.) like car owners do. xtra premium really gives a boost to ur vehicle's pick-up. trust me xtra premium is the best 2 wheeler fuel available.,

SOURCE: Want carborator adjustments for jonson

Hello Gw Fowler.

Setting the jets on these old engines is done by ear, not by a particular number setting.
The knobs on the front have a screw in the center for centering the knobs after initial adjustment.
Turn both jet screws gently until you get to the closed position on high and low speed. Do not turn too hard as you may damage the needle ends. You will feel them bottom out.( you may need to loosen the center screws).
Then open the high speed open a turn and a quarter.
Open the low speed one turn and a quarter.
You will then need to run the engine on a large test tank or on a boat.
Start the engine and go to an area where you can run full throttle.
Adjust the high speed jet until the engine runs the best and add a little more open but not enough to affect engine speed.
Then slow down to an idle. Slowly close the low speed jet and slow it down more on the throttle. If it spits and backfires open the low speed a little more.
There are some nuts on the carburetor that the jets go through that tighten fiber packing to tighten the jets from turning and sucking air through them.
If the jets are too easy to turn a gentle tightening of these nuts would be a good idea.
After you set the jets, little or no adjustments will be needed.
I hope this helps you get this great little motor running smooth.

Thank you for using FixYa.

How can I properly tune the carborator for the good mileage in the Pulsar 150 DTSi ? I need to know the step by step process so that I can tune it myself. Please assist me

Hello, factory preset settings are recommended & are the best.
The engineers have tuned the bike for optimal power & economy. They have the equipment to monitor engine perimeters and exhaust emissions. This is something you don't have. I hope this helps.

What you are saying is the engine runs when there is a good supply of petrol by top feeding the carbs but not when fed from the tank.
That suggests the supply from the tank is restricted in some way.

1985 maxim x 700 has trouble starting sometimes and wants to idle at 4000 rpm or stalls when adjusted, just rebuilt the carburetor still won't idle correctly

Hi, Dlmninja and the usual suspects are:
1. Idle speed improperly adjusted.
2. Air fuel mixture screws not properly adjusted.
3. Inlet system air leak.
4. Leaking accelerator pump.
5. Loose low-speed jet.
6. Plugged low-speed jet.
7. Contaminated or plugged low-speed circuit.
8. Enrichner valve/choke not seated or leaking.

Pls tell me the actual mileage after 1st servicing? and how to improve its mileage condition? the mileage is the main hedeache after purchasing Yamaha SZR..........pls. solve it...

I have not used Yamaha SZR. But I know Yamaha bikes are not popular for fuel efficiency. Although, I can say that with proper carburetor adjustment & running the bike between 50-60 kph improves the mileage a lot. I had RX-100, to which I was getting 50-57kmpl in Mumbai. People at the time weren;t getting average more than 35kmpl. It was a 2 stroke engine. I used to make the carburetor adjustment myself. When I service the bike from the service centre, the mileage was dropping by 10kmpl. So, you adjust the carburetor in such a manner that keep the idling speed at a level when the engine is just not stopping by adjusting the idling speed screw & adjust carburetor throttle screw to the smooth noise (minimum) of the engine. People used to keep engine running at traffic signal. If the signal is to change after 20-30 secs, shut off the engine. Avoid raising the throttle unnecessarily. Try to be at the top gear in optimum distance. I was using oils from Indianoil. Any other oil was dropping my mileage. Clean the Air Filter with petrol & moist it with oil once in a month. I think this may be helpful to you in achieving more mileage.

The bike starts up and idles great. However, when you start to give the bike throttle in gear it is very sluggish and begins to sputter. Once it reaches over the sputtering the bike will increase in speed,...

Hi ice_basher

You need to check the following

1) . The carborator & air filter are proper or not.
2). The race & pickup is adjusted or not.
3). Ask your mechanic to chk the power output in bhp. Match it with the pescribed one.
4). The accelerator & clutch are properly working or not.

Your problem can be because of any of these. Please do a through check.

I have a problem with a carborator I got always an oilspill. How can I solve it?

if its an oil leak its coming from the breather meaning a valve problem.
