WRX400?

Lots of work there, but I believe almost all the parts are there. Photos by Bernie.

great win ol mate...

the wrx was the bike that was supposed to be released in 84 as the new watercooled single shock but there was a glitch and they had to postpone the single shock and thats how the w/c twin shocker came to be.in 84.5 - 85.5.........as soon as the singleshock was fit for purpose they rushed it out with the drum brake...thats what i was led to believe...others may have the true story

you are correct, the stroke concern is only a 250 change...

i really dont mean to dump on the bike...but i dont understand the excitement over a bike being a "wrx"....it just looks to me like something you could easily make by swapping the 83-84 front end on...or if you want good brakes and a better fork, swapping the 87-88 setup on?

I don't think you are dumping on the bike justinendo, you're absolutely correct.
I agree that there are no special components to be excited about, it's just that not many were sold, especially here in Australia.
Like all these things, it's a bit objective and a bit of rarity adds to it's appeal, for me anyway.

hey its a swede, that makes it a good bike for sure! i would rather have the dls drum than the first gen disc anyway

I may do the hydraulic conversion for the front brake, a friend of mine has done it to his drum Suzuki brake.

the 400-430 was a bore change the 430-500 was a stroke change

the only advantage to the 1st gen disc is that it's not allergic to water like the drum ones
ask me how I know

Does this mean a 400 cyl. can be bored to a 430? Or is the liner different?

the liner looks different, but you could probably remove it and bore the casting, but not sure
I keep a good stock on hand of spares, 5-430 cylinders with heads, down to 1-400

here are the two cylinders to compare

I think this would work well with the DLS.

funny but for some reason my brain was locked on a 250,,, and this is a 400
they say "a mind is a terrible thing"

i dont mind....at all

that, and going backwards...dls isnt the hot setup for that either..much stronger than the 1st gen tho when set up right.

kinda what yr used to i guess...you sure know a good disc after the tls....

It got the better of me, I had to go and pick it up tonight. Still loads of work, but on a positive note, it has a aluminium clutch cover so no mag rot, lots of original parts, chainguard, rear fender, fork legs look good after a quick look, it has XC suspension, much more underhang than either of my 88 WR's forks, the plastics look to be very retrievable, it has an Australian compliance plate so it can be registered if I feel the need, the tank is quite good, the transmission oil is not creamy, brakes work, original steel muffler is in great condition, complete wiring loom and a side stand that works.
On the bad news side, the motor is locked up, a tab on the subframe is broken allowing the subframe to move which is an easy fix, pipe is toast, but I have another, seat foam appears to have been cut down, ding in the rear rim.
The motor will come out first to be torn down and assess the internals, no idea what to expect!
I'll add more pics and keep updating.

ill bet its totally seized from some dumbass forgetting to put hoil in the peterhol...or if your luck is still holding from actually finding that scoot, the kicker will have let go and the pawl is jammed in the clutch gear needing simple removing and rebuilding the kicker.....my $$$ is on scenario 1.

go ahead ..pull that cover off ...make my day!!

You can bore the 400 cylinder out to 430 and the 400 cylinder will take the 430 sleeve. The cool thing about the 400 cylinder is after you use all the oversizes for the 400, then you can bore out to 430 standard(86mm) and use available over sizes for the 430. Plus the 400 has the nice reed that the AC 430 did not get and the 87 430 ended up with after graduating and became the long lost 430.

Good to know, my 430 is on last bore so someday I,ll need a cyl. but not yet.
