on the rear brake design take a look at your rim it will have the date of manufacture as in 4-85

here is a picture of the shock guard

Ok so basically to sum it up its 87 from forks to swingarm excluding the motor which is 86 to 82. The swingarm and brake mechnisms are pre 87. The 87 part is XC or WR. The motor has lighting coils so its either a WR or XC. Or mis matched like everything else. As for the size of motor, its between 400 and 500. Which I was recnetly told 430. Whew. That's a little confusing. The best part is thinking that at one point in time someone had 2 to 3 husqvarnas and basically pieces together the better ones. Oh by the way the rims are Nordisk in case anyone was wondering.

1-87 on the front 6-84 on the rear. Boom, puzzle sorta done.

the rims are correct in Nordisk, most parts were actually quite interchangeable in the 80s, the bike will be fine if you fix the brakes and add a shock guard
personally on all my bikes I take them apart all the way to the frame and go through everything so you don't break down while riding a 225 pound anchor is hard to push back to your truck or worse yet is a failure of something that causes you to get hurt
get some Bel Ray marine grease and some locktite if you want I to stay put use locktite if you want to service it use the grease
sounds like you have a 430 from your description and the XC you see in the pics is one, they are a blast to ride and haul arse
but back to the vibration issue they do need a lot of attention and locktite to keep them on the trail

the 6-84 was my original guess of an 85 rear backing plate and to be more accurate whole assembly
hopefully they used the 87 88 spacers and did not bow the swingarm to fit it as the assembled wheels with spacers are different

Awesome. Great advice. I think its cool how I joined this place a couple days ago and everyone is so helpful. I've been on a few other forums where I was a member for years and still got treated like an out cast. Cafehusky rocks.

It's a 430 or a 400 for sure. If it has a Motoplat it would be a CR ignition as XC came with SEM. 250s cylinder didn't have the Husky gun site logo on them. If it was a CR it would have a different brake arm of course that could of been changed. If you look by the spark plug hole it should have stamped 430 or 400 on its small. 87 CR did have the " center tube" on the bottom frame. Both My 87 430 CRs have it and my brothers 86 CR 250. My guess is it's a 430 XC that some one took the SEM ignition out of.CRs had 5 speed transmission and White Power 4054 "upside down forks".
I have 4 87s 2 430 CRs 1 430 XC 1 250 WR. I will look at my CR jug number tomorrow and let you know. It's been super cold here in Ohio and we have like 20 inches of snow or I would check tonight.

there are some good people here and lots of past experience to add

I wish it had sem I wanted to try the Chinese coil cdi whatsit since I've got a pile of em. Oh well I'm just happy I've got a pretty bad apples bike even with the interesting merging of parts, and a sweet online community full of good ol fashioned hands on expertise.

87 and up engine numbers are cagiva and have no relationship to Husky engine numbers and make no sense on the Husky charts.
I've fallen into that trap with a 87 Wr250.

Do up your swingarm bolt crazy tight and see if the vibration gets less.
If it does then there's a good chance the rear engine mount hole is worn.

the engine numbers are not for 87 cases on this particular bike as he has the bolt on flange behind the sprocket

You have an earlier WR type backing plate on the rear wheel The CRs plates have lugs for the floating armand starting in 1986 the WRs got the non arm plates that have a channel on the plate that mates onto a lug on the swingarm.

Ok. That makes sense on the brakes. One question I do have though is what does the swingarm belong to. I know there are differences in the models. Here's a pic that shows what may be the only way to ID the swinger.

Oh yah I took it for a ride yesterday. Holy balls it has some pep in the step.

So what is it, 250, 400, 430, 500?

The swingarm is likely CR or XC. If it is WR there is a rail for the WR plate to locate on about 2" forward of the rear axle on the inside of the right side

whats the 3 hole bolt pattern just behind the pivot of the left side? my xc kickstand mounts with 2 bolts..

It is kind of hard to play this game long distance. I note that the mono shock bikes (I have whole or in pieces ae te wr xc) the brake cable (not rod) attaches to an arm that points up. One way to assess how much use a bike has is to look at the top of the swingarm where that cable rubs. I see the steel round tube swingarm compatible down little arm and the later cable that I have always seen attaching to an up pointing lever. There are more brake cams, levers, backing plates, hubs than one might suspect. It is pretty easy to modify the arms with a welder though.

I see that the swingarm has a cross piece in front and to the rear of the shock. I have seen that on 86 ae, 88 wr and te. No matter what it came off it is the one I choose to use I sure don't have every model and year in my pile. It would be pretty tough to get anything but an 87-88 to work out on what I see as the linkage is much different than 85-86 and quite similar to stuff for at least the next 10 years, well at least on the four strokes which is how this design lived on. Look for the socket at the brake area as described prior. That socket and tongue wasn't a good design at least for the long term in my opinion. I guess it is mentioned prior in this thread before 86 the aluminum swingarm didn't use this tongue and groove. Cr being similar to the suzuki full floater in my estimation and discussed prior.

Might go back to post 55 here and examine that picture and your bike. I see the brake cable low there.

Looks like a CR swing arm to me.

I have attached a photo of a 87 CR frame and photos of both sides of one of my 87 430 Crs. The last numbers are 1614596 the jug by the carb flange. Your bike has the XC/WR tank. Look how much higher it is then my Cr. I still think it is a XC. I will get the numbers off the jug of my 87 430 xc this weekend for you. Glad you like the bike they are a riot!
