i had an old mid to late 90s jr dragster laying around the house and it had a tav on it and my step dad and i put it on my MB200 its super awesome ran great 2 weeks started it today to ride and go ride my practice track ride it for 10 mins then i shut it off to get a drink of water and then i start it back up and start to take off and it was like if you have a hand clutch on a bike or quad and you pull you loose your power it was like that kind of a feeling and it would only do it until i got to a faster speed then it wouldent do it any more any body else have this problem? thanks
