i bought a 2004 raptor 660 and the guy had jeted it and it would start but bog down so i replace the jets the jets were 140 but everything was stock so i put stock jets back in. well it starts good and idle great. but when u put in gear and try to take of it has no power it seems like its in neutral, its goes but slow i push the gas and all its doing is reving up. i shift gears, all gears go in perfect but still no power... HELP!!! plz
