Hey everybody, I have a 1999 WR400F... I bought the bike used about a year ago. The previous owner said he hadn't done any modifications to the bike, so I am assuming the jets are stock. Since I bought the bike I have uncorked the exhaust, cut the throttle stop down, and put a UNI airfilter on it. These mods(At least the first two) helped the performance of the bike greatly. My bike is really hard to start. Takes me 5-10 minutes to get it started if it is cold (Hasnt been ridden in a couple days). If the bike is warmed up, it runs great! Starts first kick everytime (NEVER touched the Hot Start EVER!) It doesnt POP on decel, but I do see my header pipe glow red when I let it idle to long. I have read that some people try blipping the throttle when starting cold, but when I have tried that it kicks me back! I usually pull the choke out, kick it through with decomp. five times, and then find TDC and go at it. It will finnally start, but it takes a lot longer than It should. Once I finally get it running, I have to "Half-Choke" it because it sounds like its going half throttle... and without choke it dies. Is this a jetting problem? I ride at sea level 100% of the time, in Alaska so its usually 50-70 Degrees out when I ride. Any help would be great, thanks.
