Hello

I had the same problem before on one of my bikes. After changing both headgaskets, the problem was solved.

Generally bubbles in your coolant indicate a bad head gasket. Get an air compressor and pressurize each cylinder in turn to find out where the problem is, or you can also just do a compression/leakdown test to find the failed cylinder/gasket.
