If popping on decceleration its most likely to be idle speed too low this causes the decompressor arm to activate, also check the clearance of the arm to ease starting clearance should be 0.35 mm

Check your plug. If it is the wrong gap or wrong style it could be too hot of a plug. for your bike the plug that should be in there is a NGK IFR8H-11 they should cost $12.30. It's expensive but cheaper than an engine rebuild.
Also it could be running lean, check to make sure the fuel filter is not clogged, or that the gas is stale. If the bike has been sitting for longer than three (3) weeks then you need to clean your Carburetors. It is about $100 per carb with most shops in the US, pricy but if you don't know what you are doing you can spend a lot more doing it yourself.
Make sure you keep the oil filter clean and lubed properly, dirt destroys engines fast.
