WR400F restoration help?
Posted April 30, 2014 - 03:27 AM
I have recently purchased a 1998 wr400f. It is in ok condition and has the usual wear a dirt bike would have. Could anyone help me as to what I should change/replace to make it a good looking and reliable bike. Any help is appreciated!

Wow! that is one very generalised question!
Lets see, replace everything that is dull/scratched with new/blingy items. There is no limit other than your budget. I have a 98' WR400 too and the previous owner spent heaps on plastics etc. ie wr450 headlight, new seat cover, yz400 pipe/side number plates/rear fender, custom graphics and I have just rebuilt it as a 426. When it's in motard trim with chrome 17" rims with gold talon hubs and a 320mm front disk, no one can pick what it is!
reliability wise - change the oil and filter/check the valve clearances/if it starts/idles/runs ok then just ride it and enjoy the power!
ps. keep an ear out for a noise in the gearbox, my just ate forth pinion gear, hence the 426 rebuild!

valve clearances before anything else. no point having a blingy bike if its going to drop a valve. Valves are much cheaper than a new head/bottom end.

Start searching and reading
You question pretty much requires a book full of information
We don't know what you will understand or are ready for.

Thanks for your help guys. I will get it checked over by a dealer first
I would strongly recommend that you do not take it to a dealer for anything.
Dealers are skilled in removing bikes from crates, changing oil and tires, and other basic stuff.
You should find a local 'tuner' in your area who works on Yamaha YZ/WR's and have him look it over.
