those pins to help the rim locks and missing parts sheets

Responding to a post lately got me to wondering which bikes the rims with 18 pins came from. I pretty much switch wheels, have the earlier one (for what I have/use eighties) with wider shoes and the later one with thinner shoes, not much for cr stuff over here so I don't have to worry about those differences if any. I got frustrated but it seems they came on wr only in 1983, in 1986 to 1988 they came on everything except cr. Upon trying to figure out what came on my 88 te 510 the four stroke sheets have no wheel page. Not sure about what years they made auto or marketed them buy chances are that for the dual shock frames the supplement for the auto doesn't have wheels either and the auto designations aren't on the normal sheets. For what I have I know the 420 had a conical hub and no pins.

Would I be right in assuming the dealers had more parts sheets than halls has on line or on the cd you buy off ebay?

Have I pretty much figured out those pins wr to start then everything but cr later? The holes for the pins are in rims with no pins if I recall.

I have pins on my 82 WR430.....and on the CR390 frankenbike. Who knows what those wheels came from though. 82 WR should be all original.

I have a 78 390WR. Both rims are original and have never been messed with. They both have pins.
This subject came up at the weekend. The concensus was that (in 78) only the WR's came with pins. Is this correct ?

It would appear that way from the parts sheets I have, the auto sheet shows the wheels that year and no pins. I suppose I forgot about the front ones, I find on the new stuff with disc brakes I end up having to readjust the front tire a few times over it's lifetime the rimlock doesn't seem to do enough.

Sorry to resurrect such an old thread, but I would like to ask a question about these rims that have pins in them.

The wheels I will be using on my 390 have these pins, and I want to know if the pins are enough on their own to secure the tyre, or is it necessary to use a security bolt (rim lock) as well?

I cannot see how the tyre could move once it is correctly fitted and the pins have buried themselves into the tyre. Anyone have any thoughts on this? Thanks

The Pins will hold fine as long as the tire is inflated. The pins were popular for quick on trail flat repairs. you can always use a rim lock as well as the pins, no reason to remove the pins.

I agree on the WR only. I have a 84 WR500 and it has the pins.

Thanks guys.

I have used self tappers through the rim instead of rimlocks on some of my scramblers for years. A tip from Fluff Brown of AJS Stormer and Cotton fame. You do have to be careful that they are not to long! And they are not much good after a puncture so fine for M\X not so good in the woods, but so much easier than changing a wheel with rimlocks

I have a set of these " PINNED" rims for sale

I have both 21" front and 18" rear rims with pins in very good condition for sale if anyone is interested. Reported to be from a 86 250 CR. PM me for detials.

Do the same thing on my drag car. Started glueing them with 3M super weatherstrip adhesive, pain to change though but thats every two years.
