This is why it happends with a lean top & fat lsn.After a high speed run,You get more O2 that fuel so it does this surge untill the fat lsn kicks in.

If its not loading up , it stays running ,not excessively hot and making enough power to keep u happy i say its good , fuel pressures from tanks do some funny stuff. The novarossi carburetor definitely needs a good consistent fuel pressure from the tank , ive seen tanks cause inconsistencies, pipes cause inconsistencies, holes in pressure line ,etc. Etc.
