Guys I was going to get rid of my KFX400 or trade for a 450 sport quad of suzuki or yamaha brand. Well I decided to check my spark plug, it werent too good. I know on my race car to take them out after every pass and check them/clean them. Well I let this one go.

The quad was not running well at all popping on startup and real sluggish. SO I pulled and cleaned the plug. I got a new bike just by cleaning the PLUG. I am going to order 3 so I can keep them handy and clean...

Guys/Gals make sure you have good plugs and air filters...

Just a little reminder....
