Hi all,

I am having a strange issue with my sons new to us RM 125 (1998), I adjusted the float level all works fine for 1/2 hour then fuel just starts flowing out the overflow, any thoughts?

Thanks

Alan

how does the float valve look?

Could be the float is cracked and filling up with gas?

Float valve could be the winner, have ordered a new 1, didn't seem to have any petrol in the float, as it did it once straight after I re jetted the carb, the second time as mentioned was after 1/2 hour or so of re setting the float level. Thanks for the input, I will post with the results after changing the float valve.

does gas come out when the bike is off and the petcock is on?
or when the the bike is running and petcock is on?
after the 1/2 hour

when it happens the gas comes out when the petcock is on running or not

Ok so new float jet in, still poured out petrol, Suzuki dealer checked float, float level and new float jet all OK, they lowered float level, I put it back on bike it still floods, I lower float level again, start it 3 times no flooding, take it for a ride the next morning no flooding after 4 laps then stopping, did this another 2 times all OK, then after another 2 laps I stop to let my son have a ride and it starts flooding petrol out the overflow again. Anymore thoughts, I am going to get new fuel line, filter and vent lines.

Ok , touch wood it looks like I found the issue, when I changed all the tubing, fuel line and filter I re blew the carb out from both directions and out of the fuel inlet pipe and through the seat came a piece of rubber about 3mm in size. Looks like it had been floating around between the float needle and seat and the fuel filter.
