Just got done restoring a 91' LT250R and need some help....I got rid of the airbox and will just be running the filter right off the carb(like my raptor in my pic gallery), I know I have to rejet, but what size? what premix ratio should I run? The quad is all stock, no pipe, just a UNI foam filter and Im at sea level and usually ride at small dunes or dirt trails in 100F+ heat. Im new to 2 strokes and need your help, thanks!
