I bought an 01 426 for 1500 bucks from a fat guy who tried racing motorcross but found out he wrecks too much! it had: broken levers no seat, no head pipe, blown shocks and siezed bearings in the swingarm. it hadnt ran in 2 years.. it took me 300 bucks to fix all of its problems including a new seat and FMF powerbomb headpipe (EBAY is great) and it fired up after 5 kicks! Runs like a champ and havent done anything but ride and change the oil in it!:applause:

It shouldn't be. I have a 99WR400 and it never takes more than two kicks to start it.
Is this your first bike?
If so, learn the procedure for starting it and it won't be hard to start. Also, if you perform good maintenance you will be rewarded with a great machine for years to come.:applause:
I have owned my bike for four years now and it has been an excellent bike.
I hope you have a good experience with yours.
Don't forget to post up some pics.

Looks better than mide did when i bought it! it looks like it needs a good wash and some pledge on the plastics and she will shine! also i would take some of the stickers off, (not like all those companies are paying you to advertise for them!) Just my opinion!

the startup procedure..
1- turn on the gas (i forgot this my first time)
2- pull the black plunger on the carb (cold choke)
3- kick the kicker untel it gets really hard to kick (about 1-2 revolutions) then let it return to top.
4- pull in the decompression lever(the little black one)
5-kick it down VERY GENTLY i think the book sez 22 degrees i'd say about 6 inches from top and stop!
6-release the decompression lever and let the kicker return to the top
7- kick it, full stroke as hard as you can! (no throttle in neutral)
if it doesnt fire repeat steps 3-7
it takes some getting used to!
Good Luck!

Those arent all individual stickers FYI, they are part of a boost mobile graphics package. Search the board for 426 starting procedures, and youll find a ton of info to make starting a lot easier for you. Youll also love the bike, as they have a pretty smooth powerband and gobs of power.

Yeah, starting these ain't the easiest thing. Gotta have the routine down.

One thing people have done; install the auto compression release from 1 or 2 year newer bikes (it's part of the camshaft I believe, and it fits fine according to what I've read on this site.)

TPS and blue wire (neutral switch): (also search both topics, there is a lot of discussion about it)

The DCM, as it was once known (Decompression Cam Mod) is the absolute best single thing you could do to any YZ400/426 to make it more fun to live with. It consists of nothing more complicated than replacing the existing exhaust cam with one from either an '03-5 YZ450, or an after market unit made for the 426, such as those from Hot Cams.

If you use the OEM 450 cam, use these instructions:

That is the correct startup procedure.

As for the rust on the spark plug, is it on the electrode or on the outside part of the plug where the wrench goes? On the outside is normal from water getting on it when it is washed. To prevent that, after washing the bike, ride it around for a bit to warm up the engine to evaporate any water.
Good luck!

Ya, go with the sequential procedure, get used to it and kick it like a man. Works for mine.
