My KLE runs smoothly for a few minutes minutes (after filling carbs on PRI), then fades and stalls. The spart seem fine, even after stalling. Carby jets and float valves are new and clean. No fuel seems to get through the vacuum system. Can anyone tell me where the fuel vacuum come from and what are possible remedies? No Kawasaki mechanics for hundreds of km - here in regional Australia - so any advice very welcome. |

hi, the vacuum works off the carb, when the bike is running when you start the bike the the carb sucks air it to it and then the vacuum moves a diarafm in the petrol tap, when you switch the engine off no vacuum no petrol gets through, look on the fuel tap it should have2 pipes comming of it look for the smaller one and pull it off, then put the tap on prime ( which bypass the vacuum in the fuel tap )if the bike is running hold your finger or lissen for air being sucked in to the pipe, as some time the pipe does come loose off the carb or it may have a split in it, ( in side the fuel tap you have a rubber diafram with a seal on one end of it as vacum is created the daifram should move to alaw petrol through,hope it helps, you can run on prime but make sure you dont run out of gas, |
