Ninja JX21 Driving me NUTZ
I have a JX21 that will not idle unless I have the idle gap at around 3 to 4 mm. Every time a go back to 1.5 mm gap it will not run loads up and dies. I have replaced the fuel line and tank high speed and low speed O rings front and rear bearings. Still have the same issue, no matter how lean it is on the low speed needle still doesn't idle correct. This is on an MBX6 and the motor has 5 gallons on it. Anyone else seen this problem before?
