09 TXC450 boiling coolant?

So, I took the new bike out today for the maiden trail ride. I warmed it up for roughly 5 mins, and then off for some 2nd & 3rd gear cruises around the fields on our property. After about 20 mins of just making some easy fun laps, I pointed it towards the woods.... roughly 5 mins down to the bottom, and a minute or two up the hill... stalled the bike .. and heard coolant boiling. I found the nearest tree, and just hung out for a while. There was coolant in the overflow, but not an unreasonable level. The bike seems to start fine (QUICK), idle fine, and runs out fine. It's not as unGodly fast as my old YZ, but it pulls fine (I guess.... never been on a thumper).

I checked fluids (including coolant level) before I headed out today. I haven't opened the radiator since getting home, but I did note that the overflow bottle was almost empty (where it was when the bike was cold)

Thoughts?

Boils into the bottle when hot and sucks back into the radiator when cool.

Sure, but should it be boiling? It sounded quite violent. This the first bike I've had with an overflow bottle. I would think that if this were normal, I would've been constantly adding coolant to my other bikes without overflow bottles. Maybe it's just a 4 stroke thing, as I never heard such a racket on my 2 strokes.

If it matters... the headpipe has also turned blue from the cylinder to the muffler.

It's new and breaking in. I've not heard about a TXC that boils over constantly after it been broken in. The TE's have a fan...not sure about the TXC's. Turning blue is normal for the TI.

It's normal for breaking in a bike for this time of year to get a little boil over. I have found installing Engine Ice and a stiffer rad cap means no boiling over for the most part even in this heat on my TXC510.

You guys rock. Thanks.

Engine Ice is a valuable addition to any bike. Not saying it will cure your issues but it is definitely better than stock coolant.

I have a digital thermometer that I use when I play ride and I notice a 10 degree different between Engine Ice and stock coolant. Has to help a little on my screaming 125.

Engine Ice. It was the only way I could keep my KTM's from puking out every ounce of coolant in their radiators. Using Engine Ice in my Husky's, I've NEVER puked coolant... even into the overflow tank.

I just use distilled water and some water wetter on my TC450. Takes a lot more to get it to boil. No catch tank. There is a plastic ''T'' that is a good idea to change to brass or aluminium also.

I don't like the idea of increasing the boil temps and pressure with coolants and a radiator cap.
