Feel something's choking within my bike..

[DaDa]

Hi guys, when my throttle's bout to hit 5k RMP, it feels like there's something choking in there, and the sound from the pipe is very different from usual, can feel no strength in it, especially when riding towards slight up-slope.

 

Hmmm, it happened 2 days ago out of a sudden. Anyone of u guys encounter this before? By the way i do pump F1 Synergy at M'sia sometimes. Hope the problem doesn't come from the petrol.

Nope, this's not the usual way my bike's doing. Jus all of a sudden, every gear close to 5k RPM i feels something choking in it. Can't feel any much pickup even if i open the throttle more, yup. Am just curious did anyway encounter this kind of thingy after pumping petrol at JB? Hmmm..

riding rvf?maybe your carb rubber spoil that why the mixture is not correct that cause the lag,you can try knt to wash your carb and change the rubber. rubber 1 pic $15 X 4 + $80 washing carb

happens to me many times when i pump petrol in jb, now stop pumping there.

 

only for carburetor, here what u can do:

1) close your tank fuel-cork.

2) drain the fuel in carb's bowl.

there is a drain screw at the bottom, just loosen it.

u can see fuel drain out from the rubber tube.

done.

 

sometime u have to repeat it more than twice or thrice becoz as u have pump in jb, water accumulated in the reserve tank portion.

best on your second or third time, turn fuel-cork to reserve which is the lowest section (water is heavier than fuel).

i use a water bottle to collect back the drain petrol from the drain tube.

can see at least 10 ml of water, pour back petrol into the tank exclude water.
