Have you changed the air filter at all, may be due for a replacement?
Also, next time you get the bike warm put it on the centre stand and let the bike tick over for a while and keep an eye on the coolant expansion tank, you can see it looking under the rear wheel arch on the right hand side, and see if it fills up and boils at all.
You may have a clogged up system, which then sends boiling coolant to the expansion tank then comes out of the overflow pipe.
Once the bike gets cool again it will suck the fluid back into the system then you'll notice a dropped level in the expansion tank.
If it does do this you'll need to do a radiator flush, i normally leave it in for 2 or 3 days so it gets hot/cold/hot/cold and it gives it a thorough clean.
