when i accelerate, changing gear from 1st to 2nd gear it is smooth. But when u further accelerate and shen it change fr 2nd to 3rd gear, i exeperience pull back n surge and if u look at the rpm it will b like up down up even when u a still accelerating. However, if u r on high speed n change gear from 4th to 3rd I don’t experience the surging n pull back. Can anyone explain or share what could be the problem? At first i thought was d air filter, changed but the problem still exist.

problem as mentioned in earlier.

accelerating fr 2 nd to 3 rd gear, seems to have pull back n fwd b4 changing gear to 4th. However, if accelerate from 4th gear to 3 rd gear will not have this problem. It is visible of the effect as d rpm will be going up down up down.

Appreciate some advise. Tq
