Tell me about the 86 WR400

Kelly, I have not had model either but I constantly run into new and used part for this bike. I suppose they were popular because of the parts availability.

i have one as well. scary fast..things to watch out for,...water pump seals, kickstart shaft issues, and stator issues...
mine is available for sale as well.

Add to above swing arm cracks due to lack of grease in the swing arm and linakge bearings. The rear shocks usually need rebuild due to age. I just finished a resto of a 86 enduro 4oo ( WR ). Parts were not much of a problem as I adapted slightly different bearings and seals throughout. My engine is low hour so there was not much to do there. Hang out on EBay and you should find what you need. Install a Trail Tech speedo and just give up on an original mechanical speedo. Get a billet carb. mount/manifold. A lot of power but my Enduro is pretty controlable. And the ride was a big surprise. Where's the bumps???? I guess due to the light weight and long travel the plush ride is to be expected.

Here it is:

'86 400

This is a very good bike. Rode this for three years moving from mid pack to expert. Lives forever, Smooth power -grunt for days-keep it in 3rd or higher.
Yes keep the clutch adj., properly and keep fresh damper rings in the forks. Freshen Rear suspension at least once a year. Put zerks on the link and Sw-arm

Sweet! In 1986 I had a 125 Husky and one of these was for sale and I remember drooling over the thing! Fun to ride old stuff once in awhile! I think parts will not be to bad to come up with.

I have one with every part in the Husky Products catalog you can put on it, it also has the complete front end from a 2001 Honda cr250 on it. it does 95 mph flat out.great bike , have fun with it.

Rebuild your rear suspension before you go hog wild.

completely rebuild the front disc brake components including the re-surfacing of the rotor, then give us a ride report. I have all of the parts available.

Do you need that much brake on a dirt bike?

Steep? Oh yea, yeah I have been to Col. and here's a steep bridge here!


Show us how that brake mod goes. I was thinking SM 400 someday.

My course marshall raced/ rode an 86 400 for 10 years! Very reliable other than one bout of frozen swing-arm bearings. Too much pressure wash and too little grease. I had to use a 10 lb. pin press to get the swingarm bolt out! (sledgehammer)
Once jetted correctly, motor ran very well. His vibrated when revved, but he short-shifted and rode below the vibes except out in the wide-open desert where he'd rev above the vibration point.
Finally bought a 96 KTM 360 and rode that for 10 years.

That 87 430 that your getting the parts off of Kelly had an awesome front brake. I'm putting the front end on my 84'ish WR250 woods bike. My modern woods bike is a 96 KTM 360 EXC, it has awesome braking, kinda scary going back and forth with my 82 430XC,82 CR250 and the KTM in the stopping dept.!
