Ok, I have rebuilt this 2000 WR400F. Link is here: http://www.thumpertalk.com/forum/showthread.php?t=981792 During the rebuild I did the following modifications that "could" effect her willingness to fire up. - JD Jetting Kit - Baja Designs SuperMoto Kit with Headlight and Taillight (Also using their switch, wiring and kill switch) - Changed all fluids - Installed a new spark plug - Installed full FMF Q4 pipes - New UNI Air Filter The bike is getting spark. Confirmed that twice today. The bike is also getting fuel in the lower float bowl as I removed the drain bolt and a hefty amount drained. I have kicked for the past two days to no avail. I have tried clearing with the decomp cable pulled in and several kicks. I have also tried with the choke on and off. I am getting the motor to TDC and decomp to release and then back up top for a full stroke kick. Being a big boy with muscular thighs, I don't think it's a lack of power going through the kicker. Please help. I am at my wits end and can't get it off my mind on what could be wrong and or indifferent to cause this issue. Any help, tips, or ideas are widely accepted and appreciated. Thank you so much in advance for your help.
