@rajahasnain92 This is Tuaha Jalil from Islamabad. A couple of days ago i purchased a brand new benelli tnt 25 from Car Craft (Rawalpindi). As soon as i had my first test ride i felt severe engine misfire and constant jerks while driving. The engine stumbled for a moment, then regained its pace and this happened consistently.
I rode 145 kilometers till date, but the problem is still there. Just as soon as the rpm settles down, the engine misfire reappears, and i'm stuck with the sinking feeling.
Important thing is, the misfire isn't just between 4000 - 5000 rpm but at almost every level and in every gear.
The mechanic drained out all the petrol and filled the tank with superior quality Hi-octane (97 Ron) from Caltex. But again we felt constant jerks and engine misfire while riding. He disengaged the battery and checked air filter but the problem didn't solve.
Pso Altron X (92 Ron) was used in first tank.
Current mileage of the bike is 145 kilometers.
Did this happen with you as well? Kindly help.
