VF1000R rear wheel?

I finally got around to swapping in the wider rear VF1000R wheel and brake with the nice 160 tire. I have discovered a wobble and found the rim isn't true. What are the fasteners called that secure the wheel spars? And can anyone offhand direct me to a wheel true article?

Thanks

Thanks for the quick reply. I will contact if I am not able to straighten it out myself. I am hoping I can do it through adjusting the spar fasteners, after I figure out what type of head they are (it was too dark last night to see the details).

The wheel is probably not meant to be 'fiddled' with that way. But proceed however you see fit.

Yeah, put a bit blunter, no way. That's not like a spoke you're going to be able to tighten to true. I'd eat it and send it out, lest you overtorque and snap one of those fasteners trying to add or subtract tension. Those are small fasteners and likely not up to a lot of additional torque on an experimental basis and there's no way those are going to be useful in truing that wheel, IMO.

I was going to make a suggestion...but I am stretched a little too thin on this board! 8)

Isn't a 160 tire too big for that rim or has it been widened.
I would have thought the stock size was 130, 140 tops.
Could that be causing the wobble?
Never seen drilled Prolink rotors. I like the look.

Before I do anything, I'm going to verify the torque of all the fasteners. Then remove them all and check the rim. Then, once I know where the problem lies, I will proceed. I had no intentions of over torquing and shearing anything. Thats not how I roll (usually).

Of coarse I was warned emphatically to not cross drill my rotors, that they would crack, break, and cause a crash (about 15 years ago). They have worked good, and look great IMO.

Thanks for the replys and warnings.

What's your theory, just because I'm curious? Those fasteners are 90 degrees to the axis of the wheel. What do you hope to happen when you tighten or loosen them?

To 'pile on' with Nils, unless those are really unique Honda wheels, none I know of were designed to be taken apart. They usually have special kinds of bolts/nuts that ordinary wrenches don't fit anyway. My guess is that if yours has conventional fasteners, then someone before you was fiddling. Let us know what you find.

I saw what appears to be a composite assembly using threaded fasteners so I intended to check it out.

My plan is to disassemble, compare the spars for irregularities, and check the rim without influencing support structure. Then compare eccentricity of rim, assembled and assembled to determine cause and location. Assess serviceability.
Nils: the spars are not perpendicular to the rim. That would make for an unsupported structure at its intended service loading.
Dave: the fasteners aren't conventional, hence my question about what they're called.
Now, with my glasses on, a close inspection appears to indicate fasteners are one way use.

It does sound problematic at this point so I'm pursuing alternative options. I'll post if I discover something.

Thanks for the interest.

My VF1000F rear wheel ('83) uses triangular nuts and bolts and it has "Do Not Disassemble" stamped into the metal in half a dozen places
