The newly bought motorcycle model Haojue 1257f is worth 5600 yuan. Do you need to adjust the valve clearance after driving 2000 kilometers? What are the correct braking methods?

A new car never needs to adjust the valve clearance when it travels 2000 kilometers. As long as the knocking sound of the engine valve is not obvious, no adjustment is needed. The ejector engine will always have a "click" sound, which cannot be completely eliminated. If the sound is loud, it is best to check the valve clearance after sale, and then decide whether to adjust it according to the situation.

Whether to pinch the clutch when braking suddenly depends on the speed at that time. If the speed is fast, there is no need to pinch the clutch. Use the front and rear brakes at the same time according to the vehicle speed, and reasonably match the mechanical ratio of the front and rear brakes (you need to master them before you can use them freely). When the car slows down, pinch the clutch and downshift to the appropriate gear as appropriate, so that the engine braking can be fully utilized, the braking distance can be shortened, and the rear wheel is not easy to shake. If the speed was slow at that time, you can brake and pinch the clutch at the same time, otherwise you may brake too hard and turn off the engine.
