Motorcycle Repair: Spark plug fouling, honda gold wing, aspencade

Question
I have a 1984 Honda Gold Wing Aspencade 1200.  When I got it about 3 years ago it had 24,000 miles and just turned 68,900.  Periodically I will have the #2 plug begin to foul out.  It is only that one and always that one plug.  I will replace that one plug and it will be fine for a couple of months.  All the plugs are the same: NGK 4929 DPR8EA-9   Any suggestions as to (1) why this one cylinder is always misfiring after a couple of months and (2) a suggestion for a hotter or colder plug? or another suggestion . . . ?

Answer
Sorry to say, but I am not going ot be able to help you. If you check my profile I only work on Harleys.
I do have a couple of suggestions for you to try, however. Do a compression test on all the cylinders. Your comresssion might be down on that cylinder, from bad rings and your oil fouling.
Sorry I couldnt be more help
