The bowl vent "T" modification IMO is a must do for the KLR. Easy, cheap but not very pretty- sort of makes me think of my ex-wife......
Many KLRs give symptoms like a wet ignition when road riding in the rain due to water restricting the air flow to the carb bowl, so the "T" mod is worth doing even if it doesn't solve your particular problem.
A really interesting excercise is to place a cup of water up onto the bowl vent hose while the engine is idling. There is a significant air flow upward in the bowl vent hose which will cause water to channel and flow one side of the thehose. The engine will react to the change in bowl air pressure. This makes me think that a filter might be worth consideration on the bowl vent hoses however I don't notice sediment build-up in the carb bowl. It's still in the thinking list.
Another item to add to your check list is to make sure that the drain hole for the spark plug well in the head is open. It drains out on the right side of the head to keep the well from filling with water. If the drain is plugged and the well fills with water some symptoms often occur. I like to use some silicone dielectric grease on the spark plug cap's rubber seal as a"just in case". IMO it is also worth while to spray an ignition sealant onto the sparkplug boot, wire and coil as a precaution.
