Holy grail of frames I found it......

[Bigbill]

I purchased the holy grail of frames. I have the 83/84 cr frame and swing arm. My quest is complete. I have my milk trucks. A 84 250wr, 83 430wr and the 83 430cr. I'm golden now. I have a few '82 cr frames and a '77 wr frame.
It's 70 degrees tomorrow maybe painting.

How is that a Holy Grail of frames? There was no 430CR in 83, it was a 500.

 

[Joe Chod]

Then I must be the dali llamma.....and blessed....Have all from 125 to open bike and with even not 1 but 2 83 175s thrown in.

BTW there was no 83 CR 430.

 

[Joe Chod]

and no wr430 in 84 it was a 500

 

[Bigbill]

It's a cr250 frame. I have a 430cr for it. I have a '83 430wr and the 84 250wr ac..

I built a awesome 83 250cr years ago using a LQ 250cr five speed. I changed the swing arm bushing and blocked off the water pump and put a AC cylinder on it, with a front disc brake. I had the smaller diamond shaped metal gas tank that's on the 175.

The 83 cr frame is special to me. I guess there was a '82 cr430? I have plenty of 82 cr frames. The bottom line is I refuse to cut a wr frame and make it a cr clone except for the third tube center case guard.

 

[Joe Chod]

more than just the loop on rear different

ie full floater brake vs not
rear brake pedal setup
yadda yadda


there still was no such thing as an 83 CR or XC 430

I like the idea of putting a 430 in an 83 or 84 500 frame with the ITCs out back. The milk truck frames for the 500s had a bend in the front down tube to clear the exhaust. Not sure if the 83 250 frame had the bend, if not, the 430 may not work in your 250 frame. Anybody know if the 250 had the bend in the down tube or can you see it on your frame Bill?

 

[Bigbill]

The frame is in the mail as we speak. Should be here by Monday.

 

[Joe Chod]

all 83 frame (cept the 4 stroke some call em early 84 others late 83) the same except the CRs had no rear frame loop and the rear brake pedal setup was different and attachment point for the full floating rear brake backing plate arm attached to frame just below and behind the brake pedal. They all had the "dude is that frame downtube bent" thing. The 125 also had an upper chain roller above swingarm pivot point as did the 175. Lastly the steering stop lengths (little plastic inserts) were different for the CR (longer) than the XC/WR.

 

[MikeDi]

ok, I don't know what the heck you guys are talking about ..... but I gotta have one now!

 

[Kartwheel68]

The 430CR was in '81 and '82, '83 was 430WR 500CR and '84 all open class were air cooled 500s, WR AE and CR. In addition to what Joe said and bout the bent downtube, that is because the exhaust port on the air cooled engines exited to the left side, where the LC engines were center port. To accommodate the center port the LC frames have a "Y" at the bottom, you can not put an aircooled engine in an LC frame, the Y gets in the way. The only "real" '84 AC frames (with the 28deg rake, not the held over '83s with the 30.5deg rake) are the 500s, WR, AE, and CR.

Having said all that, I am not a fan of the ITC rear suspension, I think the shock leverage ratio is too high and its difficult to get springs stiff enoigh even for a 150lb midget like me, its a personal thing but I much prefer the '81-'82.

The 1983 250CR and 500CR frame are one and the same

As far as the 83 250CR frame I still have and the 83 500CR frame I bought, repaired, and sold the only difference between them was the damage the POs infected on them. The 250CR having spent it's entire life here in New England has egged swingarm pivot hole on CS side. While the 500CR frame came to me with a Nevada title and the triple clamps I got with it have speedo mounts on it. That only had a weld break on the left tube where meets the seat rails.

 

[Kartwheel68]

Yup, all the air cooled 83 frames were the same, the only differences were the WR/XC or CR and the upper chain rollers Joe mentioned on the 125/175.

 

[Bigbill]

The wr had a tube under the center of the case. The cr doesn't have that tube. If your running a cr frame in the woods a skid is needed. None of us can afford a cracked case. In Mass were we rode most of the trails are dried spring beds. They flow water in the spring runoff. Some are very rocky with big rocks. We can't pick the perfect line every time.

 

[Joe Chod]

yes did not mention the bottom third rail.

 

[Joe Chod]

but no idea why it is not flush or even with the other two tubes. not for clearance on any model so thats not it. just there to make the bike rocky wobbly on a stand unless you make a stand top with a cutout for that stupid tube

apparently their reasoning was for it to glide over things easier, like a boat keel or something

 

[suprize]

glides beautifully to one side on the stand and "kerash"
