I have a 2007 IIR Twister Hammerhead 200GT and am trying to find the spark plug. The owners manual is not helpful. Can anyone please provide detailed information as to where this is located?

Thx

I changed the spark plug which worked good for about a day. Now it is missing again. What would cause this to go bad this quick?

We need a little more information in or to help. What color is the plug? Is your GT stock? or do you have modifications? If so? which ones?

Running rich will foal a plug

If it is fouled again and you haven't done any mods, clean your air filter really well. It could be starving for air which could also cause the plug to foul.

Did you set the gap correctly

make sure you check all your electrical connections, especially where the coil connects in the electrical box. They have a tendency to come loose. This could be whats causing your miss. Could also be a bad coil, mine crapped out after about a year and a half. I replaced it with a Bando HP coil. No performance gain, but the Bando seems to be a better made coil than the stocker.
