petrol consuming???
-
hi all jut wana ask in wat way is petrol consume in a faster way.....by travelling in 70-80 or 100-110 speed??
-
dependin what bike ridin lah.... but mostly as long as u travel..... without havin your valve open, the fuel comsumption will not be that great.

btw i m ridin sp...wat u mean by without havin ur valve open??Originally posted by HighwayAngel:dependin what bike ridin lah.... but mostly as long as u travel..... without havin your valve open, the fuel comsumption will not be that great.

Lower RPM. 2-stroke bike doesnt close it valve like 4-stroke do, so some of the petrol and combustion energy is lost. And when u travel at high RPM, ur valve open more. Therefore more power, but more energy is also lost. Correct me if i am wrong.Originally posted by rossi_fan46:btw i m ridin sp...wat u mean by without havin ur valve open??

Heard that Phantom bike petrol consumption is high. Can anyone riding this bike give some info about this.
How much is a full tank cost?
How far can it go?
What is the ratio of km/l?
Thanks for the information 1st. -
Depends on which phantom u ride, ur riding style and how ur carb is tuned(if i am not wrong). if phantom 200, then is more petrol saving cause 4 stroke. if phantom 150, then consume more petrol cause 2 stroke. for phantom 200, i don't know much about it cause i riding 150. for phantom 150, most can go up to 200 km on full tank b4 hitting reserve. full tank excluding reserve is 9 litres, costing about $10. ratio of km/l is about 22km/lOriginally posted by Snowball:Heard that Phantom bike petrol consumption is high.

mine 25-27km/L
always top up btw 9-10L cos after 9L turn to reserve (250km)
price for MOBIL syn8000 btw $11 - $12.40 -
SP bout de same, if travel at 80-100km/h ard 25-27km/l.
BTW, it seems dat closing the petrol valve when u park increases de mileage. -
Valve is a series of flaps designed to open and close under different operating conditions. at low rpm, the valve is closed cos there is no demand for power
when a certain high rpm is reached, the valve will open, allowing more petrol and air into the combustion chamber, making for faster combustion rates and more power.(thus the higher petrol consumption)
For Honda NSR150SP and similar series, the valves consist of 2 stages. 1st stage open at ard 2-3000 rpm but this is usually not felt due to the small increase in power required for moving off. the flaps lift only a small amount
2nd stage open at ard 6.5-7000 rpm. the flaps lift a considerable amount and opens to maximum lift at abt 8-10,000 rpm. during this stage of valve operation , you will feel a sudden surge of acceleration all the way up to 10,500 rpm when the peak horsepower of the engine is reached.(watch out for 2T levels if intend to stay in this stage for some time)
contrary to popular belief, changing to high performance reed valves(eg. boyesen, carbontech, etc) does not really increase horsepower, it more of affects throttle response and gives a more accurate feel of the point of valve lift so tat rider can have good control over the power delivery of the engine. -

i think highwayangel was talking about the exhaust power valve of a 2 stroker. that's the valve that adds that kick when it opens... are you talking about exhaust power valves or intake reeds?Originally posted by ammo:Valve is a series of flaps designed to open and close under different operating conditions. at low rpm, the valve is closed cos there is no demand for power

quite true 4 me too!! that time i lazy to turn off the tap, got less mileageOriginally posted by Psycho V:SP bout de same, if travel at 80-100km/h ard 25-27km/l.
