2000 WR400F Rebuild - Process Pictures.

put gas in her :p

LOL!!! I may or may have not checked the petcock about 20 times...:smirk:

I rebuilt my friends 01 WR250 earlier this year. It was a bear to start the first day as well. I kicked until my foot hurt. We ended up pushing it to get it started (hold the clutch and decomp lever, dump clutch, dump decomp). Starts after 1-2 kicks now that it's broken in.

Ya it was a tiring day of kicking. Going to test for spark today and put the carb back to stock settings and see if that will do it. A buddy of mine said that since it was dry for so long, that may be reasoning as well...

Does anyone know the stock settings for air/fuel screw and for the idle knob?
Try about 2 turns out to start with. If you have to go more than 3 to 3 1/2 you need a bigger pilot jet. Did you open the carb drain screw to make sure the bowl filled up?

No I didn't do that. I will do that today after checking for spark.

I'm hoping that she was just being fiesty and needed to get wet for the night. :smirk:

She is getting spark!!! Very happy to eliminate a lot of wiring out of the equation.

Open up the carb float bowl drain and see if gas comes out.

It didn't on my new bike that had sat for a couple of years. Turned out the float needle was jammed closed. Additionally the pilot jet was blocked solid.

Planning on doing it today.

I rebuilt the carb with a JD kit so everything in there should be nice and clean but you never know...

Well another day of kicking with no positive results. I posted another thread looking for help...

I just want to hear and ride this build. I am in high hopes it comes soon...

I don't have anything to offer, except to let you know that I'm pulling for ya'.

Good Luck man, I know you've worked your butt off on this bike, so I hope you don't have to mess around with it too much before it decides to start up.

Did you check if there was gas in you carb ?

I just started my 1998 WR400 after a piston and ring replacement. The bike was bought in pieces so, it has been some time since it ran. When I went to start it I gave it a couple of throttle twists to prime the carb and pulled the choke out. It would not start so, I held the decomp lever and "cleaned out" the cylinder for a few kicks. Still no good but it tried so I pushed the choke in. Still no luck so, I held the decomp lever and "cleaned out" the cylinder again and used the hot start. It started on the first kick. 100+ degrees and high humidity at 8:00pm in Memphis made the bike "think" it was too hot I guess. :smirk: I hope this helps.

10 4 - The drain bolt in under the float had plenty of fuel in it.

Good information. I haven't tried the hot start yet. I am open to any ideas as of this point so that will be the next attempt! Thanks bud!

Thanks for the support man. I've got a great chick and friends that have been there for me through this and it's been a fuel for the fire.

Fingers back to being crossed...

Hope you get it started man. Beautiful bike. That's something that anyone would be proud to own right there.

Find a big hill and roll down it and try to bump start it.

What are the hints for the hill trial?

Dump Clutch or Clutch and decomp at the same time?

When I bump start my 426, I always put the bike in third or fourth gear and just dump the clutch after getting it rolling along at a pretty good clip downhill. Any lower gear, and the rear tire will just slide. If you try it and the tire slides, try a higher gear. I've never tried to bump start mine on asphalt though, only dirt, so that might make a difference as well. Good luck.

What zlathim said. I'd also try in 2nd or 3rd gear, def not 1st.

If it's a long enough hill you can let the clutch out more gently, no need to dump it and risk locking up the rear wheel.
