250-500cc Need help identifying this bike

I just picked up a two stroke husqvarna dirt bike which I was told is a 430. There are no markings or anything on the bike. I do have the vin number if someone could help me Identify exactly what model this is. I don't have any pics yet but I will post some when I get a chance thanks. The vin is 842251951HCP24764 and there is "1614574 made in sweden" stamped on the cylinder head if that means anything. Thanks.

Looks like you have a 1987 CR240/250, the CP in the number is for close ratio gearbox (mx) The frame number for the 430 range for that year looked like this: CP2000******* For a 88 year ZHUCRCR430XJX00001+

Where can I find the engine number exactly? I need to verify the engine for sure so I can order a couple parts. I need a water pump housing and gasket and a clutch cover gasket. Thanks for the reply.

If i remember my 84wr 500 had the engine number stamped on the top of the left hand crankcase. stick some pictures up might help loads.
