recently purchased a 2010 crf 250 its not a big fan of starting easy, comepared to my 2012. also the high idle valve is turned almost all the way out to keep an idle. previous owner said he pluged in a stock ecu and the bike started easier and thought that the program in the ecu needed adjusting. the bike has a ported head and fmf exhuast. i checked the file in the computer and in the first 2 columns at 0% throttle its at -3 and ignition is at 0 so its close to stock settings. im leaning more to chasing down the high idle valve problem. i have cleaned the throttle body, the high idle valve ports are clean and clear. i have also checked my tps voltage it seams like to me i need the bike to have more of a vacuum leak . could my throttle plate be out of adjustment. chould i open the gap slightly and then re set my tps sensor? i havent put a vacuum gauge on it. is there a typical vacuum reading i should see? should i give up, and just kick it harder. im not sure if this is the right place for this question, but any advise would be apreciated.
