Just a quick check since we are in this topic, i just got hold of a 2004 model 150 Puslie. I want to tune it to give good response and smoother power delivery as right now i feel it is choking. So from the fully closed position of the AF screw much turns anti-clockwise would be ideal? I read long time back that 2.5 or 3.5 is sufficient, please correct me if i am wrong.

Once this AF is adjusted, the idle screw also needs adjustments? 1300 is ideal i guess.

Drive your bike for about 5 -7 kms in 40 - 50 km speed then adjust the screw between 2.5 - 3.5 turns out (anticlockwise) 360 degree turns / full turns. I think your idle can be in 1200 rpm so that when start the bike after a long rest it will be in 1000 rpm.

While tuning the AF screw check the rpm stability and throttle response.

Im not a mechanical guy. These are out of experience and knowledge gained from the XBHP gurus.

Yeah i know even i am not a techie in this department, but i somehow could not find the AF screw, i see two screws one if lossened drips petrol while the other if lossened it literraly comes out but there isnt any change in the bikes rpm, however, i did keep that screw some 2 turns anticlockwise from its earlier position and now today morning the bike was crossing 60kph quite easily rpm is near 1400 once its warm.

can you post a pic of the carb with both the screws?
it is the second screw that you should be turning... but if you are confused, do post a pic so that we can mark the area for you

Hi all ,

I got a solution for mileage.

Yesterday I have tested it with an 100 ML test bottle.

1st I turned the AF screw for 2.5 turns (i.e 5 half turns) from the full tight position

I drained the carb fully until my bike stopped then I filled 100ml petrol in the test bottle and drove in the normal conditions. Where there was a bit of traffic and stopped my bike in signal.

I was driving in all the gears and maintained the speed from 10 - 50 kmph

Then finally my bike started losing the throttle power at 4.5km and started jerking. Then it stopped at 4.9 and after that Im unable to start after that.

Now I turned out the AF screw little anti clockwise. 0.25 turn. I did the same as made for the before test.This time little more traffic and also some roads were bad. And at some places the road was free. In this situation I drove the bike with the same variations between 10 - 50 km.

I lost the throttle power at 6.2 km till that I was able to feel the power when I raise the throttle. After 6.2 there was slight hick ups. My bike stopped finally at 6.6km which is 66 when calculated for 1000ml.

I hope my bike will give at least 50kmpl.If it gives 55kmpl then I wud be happy.

now the AF screw turn is 5.25 half turns.

Things need for my bike are: Shock absorb , New tyres and tube, and need to flush the old engine oil with a engine oil flush and fill it with new engine oil.

Pls suggest me a good shock absorb and tyres and how to do the engine oil flush completely. Is there any thing there to to clean the engine. pls help me.

And I would like to thank PSR jee and other experts who replied and helped me a lot.

psr

So you have understood the way to tune your carb to get what you want....
Good to see your D I Y, and the way you learnt so fast,to do things correctly.
Good Luck to you.

You all need is the patience. Dont be in a hurry. even if it ten times please be patient in testing.

Im sure the company standard turn is between 2.5 - 3.5 full turns / 5 - 7 half turns. If you dont have other problems in carb.

Then it depends on ur bike maintenance that how frequent you do a genuine service.
