1凸輪4氣門頭，操作簡單，動力輸出大!
Superhead 4v+r(1凸輪4氣門)
通過使用2個進氣閥和2個排氣閥各增加氣門幕面積，實現高進氣和排氣效率。
為了達到原廠機頭無法獲得的高輸出，在原廠機頭形狀設計中，平衡了 "中心塞"、"間隔夾角 "和 "壓縮室形狀 "端口形狀。
燃燒室通過機械加工達到高精度。
最高級別的進排氣效率
閥桿直徑內：25mm×2/外：21.5mm×2
閥桿軸直徑：內、外均為4.5mm
不等節距的氣門彈簧，防止高轉速下的喘振。
汽缸蓋表面被漆成黑色。
由於包含了檢查呼吸罩，可以通過單獨購買 "集油箱套件 "來釋放發動機的內部壓力。
檢查呼吸器蓋`檢查蓋`l.氣缸蓋側蓋采用拋光鋁壓鑄筒體處理。
鍛造鋁合金滾輪搖臂
降低與凸輪軸的摩擦阻力，使其運行更平穩
最大的功率輸出可以保持在中速到高速范圍內。
凸輪軸/氣缸/活塞
自動減壓凸輪軸
自動減壓凸輪軸
在不給單元電機加負荷的情況下，可以順利啟動發動機。
采用的是全鋁陶瓷Mexilinder。
孔徑：63mm沖程57.9mm(正常)
陶瓷Mexilinder具有優越的耐久性、氣密性和散熱性。
缸體上有一個出油口通向機油冷卻器，可以單獨購買機油冷卻器套件，防止機油溫度升高。
缸體表面未塗銀色。
高壓縮鑄鋁活塞，壓縮比為12.5:1。
活塞設計為高性能和耐用性。
活塞頂部經nc加工，精度高。
■超級機頭4v+r增徑套件181cc
本套件包括機頭套件`氣缸套件`自動減壓凸輪軸套件。
*為發動機各部件調整燃油的噴油控制器必須同時安裝。
※sp竹川建議購買錐形歧管轉接套裝，可使原廠歧管的進氣口順利進氣。
*fi-con2（噴油控制器），它可以調整燃油以適應發動機部件，必須同時安裝。
*為了方便制造商，產品的規格可能會有變化。請注意，我們沒有任何這方面的信息。
