Fule reserve problem
 

The bike just stalls when out of (full>reserve) fuel,it doesn't gradually slow down. Idk if this normal cz the previous bike (klx250 2001), used to slow down and start missing on the run when the reserve needs to turned. But on the klx250(2004) it just stalls and when turned to reserve its all good :/ this doesn't happen at all times but pretty often, very hectic in traffic all the honking when stalled lol:D

*I dont have the breather valves on can this be the cause?
