1994 suzuki RM80R: problems with the carb loading up flooding. I have already replaced the float valve and seat, cleaned every port out and determined that the float does not have a hole in it. I found that the upper reeds have a crack accross the middle about a 1/8 inch on inside of reeds. the middle stem under the reeds is broken off and gone so there is no support in middle of the reeds. I have played with the timing a little but it always seems that if i clean out the carb, and crank it up it will run fine for about 2 minutes and then start flooding.
Sounds like trash in the gas supply is holding the float needle open causing the float bowl to overfill. Remove the petcock from the tank and clean out the water trap bowl (some petcocks don't have a bowl). Drain some gas from the tank through the petcock hole to help clean trash out of the tank. Install an inline fuel filter
between the carb an the gas tank.
Now clean the carb one more time using an air hose to blow trash out of the float seat and then blow out the fuel line as well. Be certain the float level is set at the proper height. This should solve the problem for you.
Please rate this solution as a "FixYa" if this solves the problem. Thanks!
Okay, lets attack the problem a different way. Check with the dealer and see if they have a Known good carb you could test out and buy if it works. Same thing with the reed setup. If not, who else do they know that might have the same bike. See if they could help out with a ten minute parts swap.
Sorry, I overlooked the info on the reed valve. My bad.
Google " suzuki motorcycle salvage ". You should be able to find whatever you need there and also Google " motorcycle salvage ". All things considered I think you have things pretty well in hand. Keep at it.

Two things......make sure your air filter is clean. dirty air filter means less combustion= all the fuel is not burning off.#2 if you get a inline fuel filter.make sure it is a little smaller to prevent to much fuel in your carb.
Like johnnyraptor said before it could be some **** floating around in the tank that has made its way down to the carb lines and is blocking of the needle to the to the float valve which will make the bowl over flow. make sure there is nothing in the bowl . i had a dirt bike that ervery time the bowl filled up it would leak out the over the flow due to a sticking needle. or it could be the reeds. it wont be the spark it will be a prblem in the carb
hope that helps

thanks for the info but the thing is everytime i take this carb apart it is a clean enough to eat out of. i am hoping the broken reeds have something to do with it. i am planning to put a inline filter on it too. but keep the solutions coming. i just bought the bike a couple of weeks ago, and it short of flooding the day we got it. i found some trash under the valve seat that i thought was it but it's been flooding ever since. I can set the float up so that it shouldn't have enough fuel and it still floods. the carb looks like its been taken apart 50 times, and the float has been bent out of shape several times,so i think they couldn't figure out the problem.
i have a new float ordered anyway.
i am way beyond this suggestion, this was the first thing i did.
keep the solutions coming.
thanks man! but i am already on it looking for parts, but my gut feeling is the carb is ok, i'm not sure if it's getting enough spark or maybe the reeds were the whole problem
2007 rm 125, I have a similar problem the bike has just been done with a new top end, 120 lbs compression. It now runs perfect for two to three minutes and when the throttle is increased to 1/2-3/4 it floods immediately. Took the carb apart to check evreything, float hieght, needle and seat, needle jet, the only thing not checked is the TPS. I don't know if this will effect flooding or not????. Fuel is spotless clean too..., Any help will be appreciated.
