Carburetor How To Tune Air/fuel Mixture On Sniper Mx Carb?

[FullThrottle T135]

sir Ive done it yesterday , 2-3/4 but suddently this morning , kapus .. Did not much the RPM..

So far so good. Tried the 2 1/2 turn out. The acceleration went better than 1 3/4. Did not do 3 because there was no change i rpm. Happy with 2 1/2 setting. No back fire and doesnt smell gas.

Maybe your setting is 3 turns or 2 1/4 or 2 1/2. Try which is best for you.

Sniper MX 2012 ...back then, before adjusting my a/f screw (stock adjustment since i bought my MC), every cold start my exhaust smells really bad like causing headache when smelling it .... but now smells burned fuel and no backfire on sudden revs or deacceleration on 100kph+ ...and its all stock except 15 42 sprocket

15 42 combi. Does this combi help to achieve 100kph quickly?

2-3/4 sir .. Good in acceleration.. No vibration at all but I was upset when the Rpm dropped .. Tom.sir ill try it again ..

carb setting is not the same in other bike because of some factore like weather, humidy, elevation.. like my bike when hot summer the bike is ok but when the weather is cold or raining the bike is going rich a/f mixture..

I did what sir @traxxas-modifier said 2 1/2 turns because im in high elevation. so far throttle response was better than stock setting.

RPM dropped when reving on highspeed? what setting suits you best? is it maybe because its too lean? more air than gas?

Sir 1 turn is equal to 360deg.rotation?

in 5th gear? try change your sprocket to 15/42 or 14/40 to maximize the 5th gear rpm...

yes

 

[tirog135]

yes

Ohml my gulay .. Ive made a mistake then . I thought 180deg only .. Hahah

 

[tirog135]

yes

in 5th gear? try change your sprocket to 15/42 or 14/40 to maximize the 5th gear rpm...

Sir , ill try this .. And see what would be the output .thanks alot

This is absolutely right. Just to add, any type of carburetor is very sensitive to temperature changes. It's just how it is. If you tune the carb when the weather is hot, expect it to change when it suddenly gets cold, like when it's raining. This is the reason engines progressed from carbureted to electronic fuel injection. The computer box will adjust the air/fuel mixture for you depending on different variables.
