Customer Question

Hi. I have a 1985 Kawasaki en450 which starts and ticks over but when you open the throttle it will not rev, just splutters pops & bangs. I have had carbs apart and cleaned everything also adjusted the float tangs so more fuel could get in, it still does the same thing also if I hold full throttle and manually squirt wd40 it revs up no problem. Is this just a carb problem or something else?

Chris :

Do you have the air box fully assembled and a filter installed?

JACUSTOMER-pr4u5qh6- :

Hi, No it has got k&n filters.

Chris : Once the stock air box is removed, your carbs will need to be rejeted. This is the reason for the issues you are experiencing.
