Need to change plugs?-NGK IRIDIUM SPARK PLUGS - BKR5EIX11 i found them on Ebay for $34.99/6 plugs/shipped. The guy i got them from was very helpful, fast and i highly recommend him. Here's the auction, try to look him up:

Anyhow, I installed them last night and these are the plugs to go with, very responsive. FYI that 6th plugs was a bitch, was stradling the motor for like 10 minutes. It sucked!!!

Just remember (3/8") rathchet/6inch extension/universal/6inch extention/(5/8") spark plug socket.
