  1. Thanks! Yeah, perfectly sense! So much sense, actually that I've already tried the hacksaw (only the blade, no handle), but without luck. But I think that vice version is probably the best bet I have. I only have to find a socket that's of the right size. Which shouldn't be impossible in my overstocked garage. Especially overstocked now, that I've sold my Chevy Suburb an two years ago and the Renault three years ago, so I don't have something to fix every bloody weekend! :biglaugha:

  2. And the deed is done. :) Bearings in place, and they worked out very nicely. The old cups (racers?) for the ball bearings can be used as spacers for the headlight fittings. So now my son's going to do the rest of the work, and he'll be back on the road. Which is in good time because the end of the coming week is the first time this year that it has been forecasted consistently over 0 all day and all night. Norway's had a rather cold and long winter this year... My southern part of the country usually has +10 degrees C most of March and 15 in April!

  3. My son's home and I'm away for a month, and he doesn't understand how to replace the original ball bearings on the 125 DX with the taper head bearing kit he got from Yambits. (Fast shipping and great service as usual, btw!). I suspect that he has to remove the part of the head itself where the balls were, but am I wrong? He says it seems to be a part ofthe head itself, but they can be knocked out, right? Is there a tutorial somewhere that he can follow?

    Also he says that the kit came with some rubber bushings. Where are they supposed to go? Are they a part of what's going to be punched into the steering head?

  4. My son has a problem with his balls. ;) Not hereditary, I know very well how many balls I have and need! :biglaugha: Now I have not looked at his because I'm not at home right now, but according to the RD125B_RD200B repair manual, which I have, there should be 19 balls both in the upper and lower bearing of the stearing head. He says he can't understand that because it doesn't look like more than 18 will fit each. The problem is that he has split two heads at the same time, one parts bike and his own bike, and he may have mixed up the balls. Sounds rather uncomfortable to me, to continue the (bad) jokes. But he thinks he has 37 balls from his own bike, and they should be OK. Then he may have dropped one on the floor and can't find it, so it may have been 38 originally. But is it possible that there are 18 balls in one bearing and 19 in the other? And which one is what?

    Or would it be smarter to buy replacement taper bearings?

  5. In Norway we're getting a new rule for bikes from the first of Jan, which says that you need to drive a "medium heavy" bike for two years before you can start with the real fun stuff. My son's getting there in one and a half year, and he's dreaming of an RD 250 around '80, same type as his current 125 DX cast wheel bike. Is it realistic to find something like this, or would it be a wild goose chace? An RD 200 DX would of course be an alternative, I guess they have a pretty similar perfomance, right?

  6. I have bought a parts bike for my son's RD (some moron backed a trailer on it in a parking lot and bent the front end), and it has a fairing that according to the seller is original. Is that really true? It fits very well, but I haven't foune any pictures of these bikes with a similar fairing. It's not so different from my own RD 350 LCII's headlight fairing. The reason I ask is that the screen is broken, and I need to find out where I can get another one. He really wants to use that fairing! ;)

  7. Aha. That's the difference. They were sold in Norway in a time where there were no 125's, 100 was the largest. From 1980 (not 1978, I remembered wrong) they came with disc brake. They were RX 100's outside of Norway. Now they are made in India, and many import those and put the parts on an old RS 100 frame:

  8. That would be interesting. I can actually get a brand new front fork with steering yoke for around £130 locally! Made for the RS 100 because there is still production of those somewhere in the world. I can phone them and ask the measurements and ask for better pictures.
