bike is hard to start when cold but once started runs revs and idles good then after 5 min of running it will suddnly flood out.the bike has not been sitting has been rode daily replaced r/r 6 weeks ago voltage reads 12.5 to 14.2 volts while running. put new plugs in today with the same results.pulled plugs and they are wet with fuel. battery is good 12.2 volts after it dies.any ideas?please help.

 

How long since the carbs were cleaned?
Sounds like a possibly stuck float.

Might try running some Sea Foam or equivalent carb cleaner
through a couple of tanks.

Best bet might be a through disassembly/cleaning.
If you can stand to wait, IDoDirt will be back soon from the Austin MotoGP.

all 4 floats sticking at once not very likely i am thinking it might be something electrical. come on guys help a brother out!

 

Does it start to sputter before dying?

 

yes it acts likeit did when the r/r went bad but 10 times worse floods out and dies will not start back up all 4 plugs are so wet fuel drips off let it sit acouple of hours it will start

 

if you can repeat it, next time it starts to die open the gas tank. Just curious

 

I'm with Kuro on this, sounds like vent is clogged.
When the tank heats up it, literally, crams gas through the system.

The vent is the smaller of the 2 hoses on the bottom of the tank.
The larger one is the gas-cap over-flow.

If the cap pops when you release it, the vent is clogged.
If so, drain the tank, hook compressed air to the smaller tube and blow into the tank.

Be sure the gas-cap is OPEN when you do this.
Otherwise, you risk ballooning the tank.

When you've cleared the clog, pour about a quart of kerosene in.
Swish it around and then drain all of the resultant debris out.
You should pull the petcock and clean the mesh filter-screen, at the same time.

Good luck, hope this helps, Ern

 

no the tank does not pop when opened. fuel pump works as it should drained tank fuel flowed smooth put my finger on small vent and fuel slowed down openn vent flowed freely untill empty put fresh fuel new plugs same results .weird huh!

 

i tracked down the problem. it seems when the r/r went bad it fried the stator plug.the wires were black inside the plug and melted the plastic.i cut off the bad part of the wiring and soldered it together.now she purrs!if any one needs an r/r try rmstator in canada they sell and repair stators too. got it on flee-bay for 59 dollars free shipping
