When I first bought my 98' WR400F, I have no starting problems... I need not pull the choke knob out... now, I have to pull the choke knob in order to start the bike.
After warming-up the bike, when I rev the engine, I notice black smoke coming out of the exhaust... But after riding a bit, the smoke is gone... This all happen in the first start of the day... Why??? :) :D :D

difficult one to answer that!

i would say that the smoke when it starts is because you tryso hard and for so long to start it.

so why doesn't it start? well the technique is a big thing with these machines and it's a point that doesn't get mentioned too often on this site or anywhere for that matter.

i think you should get a #60SJ and meet other WR riders to discuss the starting technique.

I believe that the WR/YZ family has a starting technique that is unique to other 4-stoke bikes.

Here is my drill:

Depress the kickstart lever until it resists;
pull in your decompression lever and push the kickstarter down no more than 1 inch;
release the decompression lever and allow the kickstarter to go to its' highest point;
then kickstart the bike in one long deliberate motion, gaining speed throughout the stroke.

Use the choke when it is cold; use the hot-start if the bike has gone down. The procedure is simple, but I believe that it MUST BE FOLLOWED EXACTLY.

Good luck, and I hope that you overcome the starting issues.

Have you checked your spark plug? If it's even a little bit sooty, that will affect starting. The way your bike clears up after riding is exactly what was happening to my bike before I changed my spark plug--which by the way needed changing because my air cleaner was dirty causing me to run rich. I hope it's something simple like that.
