WR 400..... backfiring, stalling

At the bottom I tried to open it up on flatter ground and it started accelerating nice then nothing, motor stalled wouldn't refire. Any ideas?

I had the same problem on my 98 WR400 during a weekend of wet-weather riding... turned out to be lots of water and cr*p in the carb, especially in the Acc. pump bowl. Take some compressed air to your jets and it should be fine...

check your fuel filter
check your breather hoses & reroute one of each assembly to the air box to avoid sucking crap into it from water etc.
