January 31, 201313 yr my 04 rev 3 keeps flooding I've done a service new plug and air filter etc, cleaned out exhaust, air box and carb, changed out the fuel an still cant get it to go??????? can any 1 suggest something else
January 31, 201313 yr was it running before service ? is it sparking if not stator could of gone down
January 31, 201313 yr Author yea good spark, it fires the first kick then floods, possibly a carb problem???
January 31, 201313 yr Sounds like a stuck float or worn needle valve seal in the carb. Turn the fuel off, drain carb, take the plug out and clean the insulator etc so it's dry (leave out at the moment). Kick the bike over 20 times to expell any excess fuel. Plug back in. Fuel on and try a normal start procedure. If the fuel floods again then its your valve or floats. When were they last set properly? Is this a sudden change of how it starts/works or has it got worse over time?
January 31, 201313 yr Two things 1) You can have spark with the plug out but if you have a weak stator it may not spark under compression The best test is a spark gap tool 2) Old gas might not burn no matter what you do When a bike is flooded, the crankcase has a puddle of fuel in it and it can be very hard to get rid of, this explains why it fires then fouls the plug, if its bad enough you can hydraulic lock it and bend a rod so plug out in a warm room for a day or two usually fixes flooding, kick the bike once in a while to sweep the liquid fuel up from the bottom so it can evaporate Also, flooding is a result not a cause, it's bad sealing of the needle and it will be happening constantly The effect is high fuel height and can make your bike run rich Outlaw Dave's trick is toothpaste and a Q tip to clean and polish the seat Edited January 31, 201313 yr by 0007
February 1, 201313 yr Author Thanks for all the help and advice guys, got er going last night, float was stuck a bit, removed and cleaned once again and she fired after a few kicks, seems to running fine now, regards R
February 1, 201313 yr On some of the Mikunis the float bowl gasket impinges on the floats and causes them to stick. Easy to trim with an X-acto knife.
