I'm learning more and more about restoring obscure classic motorcycles. Mostly - that even though it is hard to find parts, there are specialists out there that can help.
A week or so ago, I took the front fork apart. The fork tubes were pretty corroded. I thought about having them re-plated, but my friend Alex suggested I call Forking by Frank. Here's how that conversation went:
Me: I need fork tubes for a 1966 Bultaco Mercurio
FbyF: What?
Me: Fork tubes for a 1966 Bultaco Mercurio
FbyF: What model Bultaco?
Me: Mercurio
FbyF: We don't have prints for that. Send us one of your tubes. We'll make you new ones.
So - off went one fork tube, and we await the results.
Next - I've been taking apart the wheels in order to send the drums out for new brakes. Since I was doing that - I figured I'd order new spokes for my wheels as well. The place to call? Buchanan's Spoke and Rim of course.
1st call to Buchanans:
Me: I need some spokes for a 1966 Bultaco Mercurio
BSR: Hmmm - that's not in the catalog. We have a 65. Is it the same?
Me: I don't know.
BSR: Here are the hub dimensions. Go measure.
So - went home and measured. Looked OK.
2nd call to Buchanan's:
Me: I have a 1966 Bultaco Mercurio. I need spokes for front and rear. A 66 isn't in your book, but it's the same as a 65.
BSR: What size wheel do you have?
Me: 17", 28 spoke
BSR: There are two sizes of rim. One with a 16-1/4" ID, one with a 15-15/16" ID. Which do you have?
Me: I don't know.
3rd call to Buchanan's
Me: I have a 1966 Bultaco Mercurio. I need spokes, front and rear. A 66 isn't in your book, but it's the same as a 65. I have the 16-1/4" ID wheels.
BSR: OK. Are the inner's and outers different?
Me: I don't know.
BSR: Why don't you send us some samples?
Me: Well - I've already taken apart the rear, and I can't remember which are inner and outer.
BSR: You can send us all of them, it's OK.
So - I bagged up the rear spokes (long ones in one bag, short ones in another) and the front ones - freshly disassembled (insides in one bag, outsides in another) - and boxed them up to go to Buchanan's. I'm actually glad they asked a bunch of questions. These are all custom made - no returns! Very nice people to deal with as well....
