Why does the throttle of Changyong 1115 fluctuate?

[SamuelDella]

The fluctuating throttle in Changyong 1115 could be due to a clogged fuel line. How to handle unstable motorcycle throttle: Check for blockages in the air filter and carburetor, ensure the fuel line is unobstructed, verify if the carburetor's air-fuel mixture is incorrect, inspect for air leaks in the intake pipe or valves, and examine the spark plug and ignition system components along with their wiring for any issues causing misfires. Also, check if the choke is closed, whether the carburetor needs cleaning, and if the fuel delivery system requires servicing. The importance of motorcycle throttle control: During startup; Starting requires sufficient torque, which varies by vehicle type and displacement. Some bikes have low torque at low RPMs, requiring gradual clutch release while applying throttle, while others may have enough torque at idle to start without throttle input—here, clutch control is key. During deceleration; Braking isn't always necessary—smoothly rolling off the throttle while downshifting can effectively reduce speed, though emergency situations demand coordinated brake and throttle use. In corners; When entering a curve, the bike leans to counter centrifugal force, making balance precarious. Braking becomes a harsh control method here as it disrupts equilibrium, whereas throttle modulation offers superior speed control. Maintain throttle in the linear power/torque range for instant acceleration or deceleration readiness. During gear shifts; Gear changes are deeply linked to throttle response. Different gears require specific engine RPM ranges for immediate power delivery—all controlled via throttle. The shift moment creates engine no-load conditions where abrupt throttle input may cause RPM spikes, leading to post-shift power instability and jerking. Thus, execute throttle-off shifts with simultaneous throttle blips. Downshifts requiring smooth power maintenance need slightly higher RPMs for better acceleration.
