Which 2 stroke oil should I use for my competition bike?

Millers KR2T is a suitable mineral, 2-stroke oil for both competition karts and bikes.  It increases the sealing/compression on the bores which leads to power/torque gains.  It is suitable for use in a motorbike unless the engine specifically needs a semi or fully synthetic oil in which case you should use Millers ZSS 2T (semi-synthetic) or Millers ZFS 2T (fully synthetic).

Synthetic oils last longer than mineral oils such as Millers KR2T, but if the race bikes/karts are stripped and re-built often, then Millers KR2T is absolutely fine for use.
