CDI for HSUN HS400ATV-2

[Plutso]

Does anyone know where I could find a cdi for hisun atv, specifically HSUN HS400ATV-2, year 2007 and vin LWGZCSL0X7A080983?

The problem is that when you accelerate hard, the engine dies off and/or starts banging. At a steady speed everything is fine. The fault is more likely to occur when the engine is warm. The repair shop thought it might be caused by the CDI, but doesn't know where to find one for this model, especially here in Estonia, where is no any HSUN dealers
