大家安安
我的四期二代勁戰大概在最近兩千公里出現頻繁熄火狀況
一開始是冷熱車都會 停紅燈前放油門滑行就有機率熄火
以為太久沒大保了就給三萬公里前幫我重做過汽門的YAMAHA店家清噴油嘴跟節流閥
結果這次保養完後換成停紅燈時怠速不穩 偶爾會直接熄掉 不過再發動都沒什麼問題
後來回去幾次反映熄火依舊 店家似乎也沒頭緒 就換了一間店處理
新的店長分別測量了我車的缸壓跟漏氣狀況表示:「缸壓正常但在漏氣」
看到我節流閥那個負壓膜只剩一圈皮(幾萬公里前破掉後就這樣處理到現在)建議換掉
結果換完貴森森的噴射負壓膜後狀況仍未改善 其後陸續遇到電系的問題
依序更換了新的:整流器、電盤內仁、電瓶、火星塞、高壓線圈、空濾 以上全原廠
因為懷疑節流閥蝴蝶閥片使用太久磨損 也換了個全新的節流閥上去
爬文後也請店家調整了汽門間隙 保養更換完這一輪後,目前熱車完全不會熄火,
車子也變得非常好騎,唯一的困擾就是,
「放隔夜冷車狀態後騎出去約100公尺的第一個巷口 若油門全放幾乎100%觸發熄火」
然後再發動一觸即發 接下來也都不會再熄火了
因為聽起來很像汽門漏氣或裂缸頭的症狀,因此也重測了缸壓,測出來是13左右
記得在原廠的正常範圍內,日前找了台南老搪缸店跟師傅諮詢過這情形
他要我先加汽油精騎兩桶看看,如果還是不行再考慮下引擎檢查汽門跟缸頭
目前兩桶已經騎完了,還是一樣,因此上來請問大家:
在缸壓完全正常的情形下,汽門仍有可能會漏氣導致冷車熄火嗎?
是不是建議還是直接下引擎重作汽門最快?謝謝
