I solved a similar deceleration backfire on a CH250 by removing the 112 (lean) main jet on a CH 250 and using a 115 or 118. The CN250, which uses a leaner 110 main jet, could also benefit from the main jet enrichment.

Then when the engine does fire, these un-burnt gasses are ignited in the exhaust pipe, causing the backfire. Newer Virago carbs have an 'enricher circuit' which cuts in on deceleration to help this problem. Earlier carbs do not have this.
