First - check your watrerpump weep hole, make sure it's clear and check for a drip under your bike in that location when you park it or are warming it up - if you do have a drip there, it's an indication that you need to replace your water pump shaft and seals (2) - a common issue on all bikes.

If the weep hole is dry, then check your oil, if it's milky, you have a blown head gasket and it's leaking into your oil.

If the oil is OK, you may have a leak into your cylinder - is your bike smoking white or smelling sweet out of the exhaust?

If none of the above apply you will have to look for an external leak like at the rad or on the hoses......

not too hard - download a manual from yamaha of australia - they have them online. While you're in there check your valve clearances and replace the shims if they need it.

Just put clean water in it 4 now -- C what's up first --:bonk: -- you can drain it and flush it later -- find the problem and fix it first -- mixing diff. brands(color's) of antifreeze is not recommended practice. You can do a search on this, but a good quality preston with de-mineralized water will work!

-- Curios to C how you make out?

The bottom gasket is called the base gasket. The only one you have to worry about in your situation is the head gasket...if that.

would a touch of blue smoke on start up indicate head gasket?

No - that's oil. Head gasket leaks will produce white smoke.
Probably somewhat normal - esp. on first start if it sat a bit - as long as it disappears almost immediately.

Strange that you'd use all the coolant in the reservoir one day, then none the next - definitely keep an eye on this.

Have you checked your hose between the rad and the reservoir for pinches or cuts? Was your rad cap on properly that day?
