A good question and you will probably get several answers.  There is a thread on spark plugs further down this page.  NGK B8HS  work ok for some people but may foul if not ridden hard enough or the oiling system is giving too much. In this case NGK B7HS would be a better choice.  There is a theoretical advantage using a projected nose plug and I have been running NGK BP8HS for some time now with good results.  There is plenty of clearance between the plug earth electrode and the piston crown.
Whatever you decide always carry a spare set with you - it's a 2 stroke!
