1999 wr 400...looking for some info and feed back..

9 posts in this topic

i am going to look at a 99 wr 400 tomorow and i am wondering what if any were the service recalls on these bikes? any issues with the engine i need to be aware of? suspension?

and here is the ad for the bike

1999 Yamaha WR400. GPR dampener , Skid Plate , Radiator Gaurds, Clark Desert Tank, SRG Seat. Powerful bike that I don't have time to ride. Stock parts also. 3rd owner... clean and clear title.. and for 1700 BO...

Keep in mind all of my bikes before this have been 70's and 80's dinosaurs...:ride: so this newfangled monoshock setup should be nice:ride: ..lol...

I don't know about recalls, but in general, these bikes are as reliable as a claw hammer! The only issues that I am aware of both have to do with the crank. The primary drive gear is held in place with a woodruff key (later models are splined). You need to stay on top of it to make sure the nut doesn't loosen and allow the key to shear. Second is the small end of the connecting rod. They up-sized it by...I think 2mm on the 426's. I haven't read a LOT of problems with the small end...

Overall, though, I wouldn't worry much about those things...failurea are rare. Just look for good maintenance practices.

ok cool.. Should i just pull the side cover off, inspect the clutch (while im in there) and remove the gear inspect the crank then reinstall with a little blue loctite? Ill probably lend up askin my yampro instructor about it... and are 426 guts the same? crank, stroke, bore..etc...

400's were over square I think, bore diameter was larger than stroke was long. Super fast revving.

426's were square, or equal in bore and stroke I think.

My 99' was a beast:thumbsup:
