99 WR400 Rebuild

Hi Guys thought id share my rebuild of my WR, i think it has got a tad out of hand from what i first intended.

It first started with an eBay purchase sight unseen, it looked better in the pics but it was a good runner and had new tires so i thought i would fix it up a little.

I brought new plastics, pipe, bars, chain, sprockets, rear disk, new pads, headlight, vapor trail tech speedo etc. It came up nice but still rode the same.

I took it out a few times and had some fun, then it developed a water leak at the bottom of the barrel at the front of the engine. Then i went shopping on eBay again and brought a gasket kit, every bearing, cam chain and all the bits i needed. I stripped the bike down and fought with the swingarm bolt and eventually got it apart and down to a bare frame.

I then got the Frame and engine Soda blasted which turned out great, now time to paint it all and put i tall together.

Once the frame was painted i cleaned up all the bolts and painted the brackets etc. I then put the motor back in the frame and pulled the top end off to replace the gaskets.

I also decided to replace the piston and rings while i had it apart so once i purchase them i will put the top end back on.

I then sand blasted all the brake calipers, pegs, levers etc and painted them.

I got a bit carried away with the swingarm, i polished the sides and top and painted the rest. Came out pretty nice i reckon.

This weekend ill re assemble the brakes and handles etc and put them back on.

This is how the bike sits now

Great work, and attention to detail! :cheers: I look forward to seeing it completed and the pics along the way. Welcome to TT by the way.

Take great care in flushing out that frame! I had mine sandblasted once, and thought that I had blocked off all of the oil passages correctly, but then I decided to flush out the frame to be safe and I couldn't believe how much grit came out!!! You don't want that stuff to go thru your brand new engine!!! Maniac

I definately will be flushing it out, it was soda blasted though so hopefully it isnt too bad it is only baking soda after all.

I still have a long way to go with it yet ill get it done one day.

I love frame up restorations!! I had no idea you can just sodablas an engine like that??!?! any damage to the seals or rubber parts?

Did you add any type of finish to the engine after it was blasted? like clearcoat

You got me thinking, i might get my engine done now.

Awesome man you beat me to it! I've got a 99 that I was considering doing the same things to but now that I've seen yours I really want to!

The engine came up great best thing about soda blasting is you dont have to clean any thing like you do with sand blasting. The parts went in very dirty and oily and came out great.

I painted the engine with 3m aluminium engine enamal, im going to do the side cases in a darker gray like factory.

Apparantly soda blasting doesnt damage rubbers or seals and they can even take a layer of paint off at a time, i highly reccommend it.

thanks mate, yeah im sure for the first few rides i wont want to go thru any mud and get the thing dirty but im rebuilding it to ride not to sit in the shed and look out so it will definitely get dirty.

It should ride like a new bike when im done hopefully.

Nice job, keep the pix coming.

Slowly but surely its getting there, put the radiators and force guards on, most of the electrics.

I still have to buy a piston so i can get the engine back together. The rear shock is yet to be painted and i also have to buy the pivot links as i had to cut the other ones off when i pulled it apart.

Can't wait to get the money together to fix up my 400, I love these bikes! What type of paint did you use for the frame, I can't seem to find the old PJ1 Yamaha blue anymore.

i used the PJ1 paint, my local yami dealer stocks it. I done a few coats and then a few coats of clear.

I ordered a piston for it today should have that in the next week or so, im loving the aussie dollar at the moment 1.05usd :thumbsup: i might have to do some more shopping online.

Not much progrss is getting done at the moment im in the process of buying a house and getting married all within the next month :confused: but i will post updates as i go.

if you don't mind me asking... how much $$$ you got into this thing? i'm still trying to sell my 07 to fix up my 99

i think im upto around $6000:aussy: including the bike $2200.

i tend not to try and count or tell the missus how much ive spent on it other wise she would shoot me

A new WR over cost $12500 so i thought if i can rebuild mine for half that why not.
