Ok Guys, Need Help On A Few Items. Just Traded A Kdx For A Yz400 So I Have A Few Issues W/four Strokes. First, Hard To Start! Runs For A Second Or Two Then Dies. Try It Again, Runs A Second Longer Then Dies Again. (when Cold) I Have To Do This Over Until She Will Stay Running. Ideas? Also, When I Turn Off The Throttle It Takes A Second Or Two (or Three) For It To Idle Back Down. Adjustment? The Bike Is Stock Except For A T4 Exhaust (hopefully Jetted For It???) I Have Had Fours In The Past But Nothing Like This. Any And All Help, Advice And Tips/tricks Would Be Great. Thanks.
