Jeeks:
You mean you're getting coolant in the cylinder?  If so, what makes you believe you're getting water in the cylinder?

FuriouSly:
Did you ride the bike after you put it back together?

To check if it is really water being burned in the cylinder (white smoke coming out of pipe) you can watch the coolant level if it drops.  You could have a crack in the cylinder/water jackets and leaking in.

Also,  the spark plug will have a white/gray crusty/moldy looking film around the isolater  (white ceramic part) instead of being gray/tan/black/clean.  Generally a bit longer term result for the plug though.

Very possible you have condensation/water in the fuel tank or fuel supply.  Sometimes you will get water in the expansion chamber (fat part) of the exhaust pipe,  usually from pressure washing.  This could cause white smoke.

Some info to chew on....

KXcam22:
Good points Sly!  Pboy, Also keep in mind that water entering from the water pump seal will turn the trans oil milky -but it can't get into the engine to burn.  The only way coolant can get into your engine is (as Sly said) a leaking head gasket or cylinder cracks. As a sign to look for, a leaking head gasket will often cause a wash mark on the piston crown (it washes the carbon off).  Hope this helps. Cam.
