    Ok, my dad started it up and was tryin to adjust the air screw but it wouldnt run long enough for him toget anywhere. I need a new plug. We have the plugs we use for the snowmobiles and they are like 9's or somethin, and the one in my r was an 8. Will a 9 be ok or will it burn it up?

    Hey we fixed it. We just replaced the plug and my dad noticed it wasnt revvinn all the way it was cuttin out. He held it wide open for a few seconds and it fixed it. It got all its power back, maybe more. He thinkks there was carbon built in the exhaust (i think thats what he said...) but anyway its fixed and badder than ever.

    Btw, after he tested it out on the dirt road I looked at it and there was probably a 200 foot burnout mark with only about 6 inch gaps where he shifted :O

    this thing is a beast, i cant wait til i learn more about it and can start modding it
