《該車現況》
車行維修吃機油問題後引擎出現明顯搭搭聲
且時速約60後回油排氣管會放屁

感覺上跟俗稱鳥仔聲很像
爬文查汽缸搭搭聲可能原因
包括汽門間隙沒調好 間隙過大、正時反180°
想請問是否還有可能的方向嗎?
此次維修零件:汽缸組更換 汽門整新(汽門換新 汽門油封換新 汽門研磨)

我以為正時對準了 內鍊條調整器壓下去後就又跑掉了
無論往哪個方向調一齒都不能讓二個圓平行
這次有換到跟正時可能有關的推測只有內鍊條導桿
打算先截短內鍊條或者用換內鏈後再看看

更換內鍊條後重對正時
正時只差半個小圓點
如下圖,用厚薄規抵住凸輪軸確認二小點是否平行,如平行應該小圓點中間
但目前是在小圓點邊邊

汽門間隙重新調整
敲擊聲已大幅下降
而引擎聲依舊沒原廠好聽
推測與副場缸組有關
新問題:
汽缸頭蓋螺絲滑牙
結論:
花了5000把只是吃機油的機車修成:
引擎異音
汽缸頭螺絲滑牙
無法騎行
加上2、3月已經花了3000修理電系 整流器......
