----Oh I forgot to mention. In September the bike idled fine with just
a pipe running out of the engine (no muffler) Yesterday after replacing
it with the stock muffler the bike would run well only with the choke on.
It did sit without being started for about 4 months. Not sure if that
matters much. Installed a new battery.

Before it was a straight pipe. Way too loud but I never noticed any
smoke coming out in the few rides I did with it. I purchased a used
stock muffler, installed it and it was blowing out smoke today. It did
not smell like oil. I know what burning oil smells like. I'm guessing
its coolant. Smells like chemicals. The color is hard to tell. Not
sure if it's white or blue or gray.

If it is burning coolant what needs to be replaced?

David,
The won't idle without choke after sitting for 4 months is probably a
clogged pilot jet. If you didn't drain fuel from the carb four months
ago the fuel probably caused the issue. Clean the jet and it will
probably idle fine.
For the chemical smell from the exhaust... check the coolant level in the
reservoir and also with the engine cold remove the radiator cap and make
sure the radiator is full. Then take a ride of maybe 20 miles and
monitor the temp gauge. Also monitor the smell to see if it burns off.
Maybe the smell is from the previous bike and contaminates inside the
muffler. Let the engine get cold and then again check the coolant level
in the reservoir and radiator. If the level changed (lowered) it
suggests a coolant leak. If the level remains the same maybe take
another test ride of 40 miles and check again. Do this a couple of times
to see if the smell is coolant. No change in the coolant level suggests
the cooling system is leak free.
If the coolant level goes down and you don't see any external leaks and
the smell continues it suggests the coolant is leaking at the head
gasket. It could be a cracked head too but you won't know until you
inspect the head.
Most owners don't have the equipment to pressure check the coolant
system. A hand pump is mounted to the radiator via a special adapter
that simulates a radiator cap. Pressure is applied to the coolant system
up to maybe 15 psi. The gauge on the pump is monitored for a while to
see if it drops. If the seal is good at the radiator a pressure drop (no
external leaks) suggests an internal issue like a head gasket leaking or
a cracked head. You can buy a coolant system pressure tester at Harbor
Freight but I don't know if it has an adapter that fits the KLR radiator.
