hi all
new here we have 2 400trxex they have been rode hard and put away wet but couldnt pass the deal up ,,,,, 1 is runnin good , the other has had "some thing done to it as it is fast as hell , this one has problems , ok it fired right up , and ran great , 2 days later , crank but no start , a bit of start spray and it ran all day and started on one bump of the button , now cranks , good spark , has fuel , will not , fire . period … it has /had a tick at idle , and would smooth out upon rpms , i figured adjust the valves ,, i have not done this yet ….. any ideas of where to look next
thx
