Doe's anyone know the the NGK plug # for the sp 700? I have read elsewhere in the forums that the correct NGK application is BKR6E, napa part #6962. According to my local napa dealer the BKR6E cross reference's to Champion RC12YC. The champion plug in the sp700 is a champion RC7YC. He says that he can't find anything that will cross reference to a RC7YC. I get the feeling that the BKR6E is just a little hotter plug and will work fine or better than the champion. If anyone has tried the NGK, will you post and let me know how it worked. My 700 is at the dealership now with fouled out plugs after 375 miles. It got to the point where it wouldn't start, luckily I had another set with me. The dealer is going to check out the carb to see if their is a problem there. The mechanic at the dealer said that half the problem is the champion plug and he can't believe that Polaris even used them. Any help would be appreciated.

 

I have around 70 miles on my machine and twice I had to pull the plugs and clean them because they were fouled. If anyone has any suggestions on how to quit fouling plugs, it would be greatly appreciated.

 

BKR6E is the correct plug.
