Carburator pun bleh guna chemical combo ye...sama ja..cuma rege murah la..saya x charge duit computer tuning..sebab bro M akan tuning manually ( carburator x da ecu..so cam ne nak masuk scanner )
Hasil bila kita boh Engine Conditioner & Valve Clean...kalau engine anda cun..x de asap punya lah..kalau engine dah lama..baru berasap kow kow...mende alah ni bukan dcarbo atau profesor x ya..ini OIL Based chemical...kalau kotor baru berasap...x kotor x da asap..chemical hanya kan cuti sensor sahaja !
