hey guys ,i need a little help or maybe alot ,I just picked up a 92 lt250 r,fmf pipe ,starts right up first kick,lots of compression,new carb,pulls wheelies all that ,but .....seems to have no mid power or top end just a dog, seems very flat..no power band at all ....I also have another 92 250 r low compression that would eat this bike ,still has stock exhaust,,,,,,,,what makes them flat in power like that??jets ?/power valve??other wise this quad is dam near like new .......any help would be great .....cause this sucks i cant even beat a 400 ex like my other LT250 r smokes them all day......

thanks alll ......steve
