hard starting

[vinny3299]

i have a 06 400ex and noticed today and the last time i rode seemed like my quad has a hard time starting up its a little cold out here right now coudl be a reason like 40 degrees give or take but its bone stock is this normal??? its like i haveta toy with the throttle and give itsome while starting.... anyone else have this prob... should i worry bout it or is it the cold weather jacking it up

400's are a pain to start when the temp drops below 55...try going up a size on the pilot jet

He's correct even bone stock 400's need a bigger pilot jet.
