1975 RD250 Trial By Fire

Ok, ok, ok! You guys convinced me! I will start trying to find a good shop around me. This might end up being a winter project, because I am moving in a few months to an area with way better motorcycle support (Brooklyn=Hipsters=Motorcycles.) That being said, I did pick up a pretty cherry CB750F that I think I can get going pretty quick, so I might just get that going quick and then make the RD my winter labor of love. The two bikes are different enough that I will be happy having both of them for sure. Thanks for the encouragement guys, I think I was just so angry at myself for being dumb that I wanted to throw the bike out a window.
 
$50 and a welder will slap those back on for you. Just dig into your yellowpages and find a decent welding shop. They'll probably be stronger than they were before.
 
There's someone at least with some good taste...

A DTT'er?
 
geez. must be nice. i would go buy that right now. in CA you can get yourself a very used, dirty, maybe running RD for that same price.
 
You could buy a cheap arc welder from anywhere between $40 to $80 and with a few hours of practice weld those pieces back on.

No, don't do that. The alignment does not have to be 100% perfect because the rubber in the bushings will compensate for some slight variances. I too would have a machine shop tread some 12mm rod. Hell, you should be able to buy a die set cheaply and do it yourself. Then, slide it through the holes where the old damper mounts were. Have a shop MIG weld it in place. I personally would MIG in this instance. Weld the inside and the outside, then chop the rod our on the inside.

Here's a cost breakdown:
12mm drillrod: $15
Die set: under $20 OR
machine shop: $50
Welding: $30 or so.

Those are estimates of course, but it really isn't that big of a deal. I was shopping around SoHo with the family a few weeks ago and would have rather turned wrenches at your place than look at another Burberry handbag.

Cool on the 750 but def keep this one going. As all here have said, re-welding those things should not be a big deal. That guy in billburg should tack another grand on to that price.

chris, why do you suggest mig for this application?

I hate stick/wire welding, so I always eliminate that process. Because he'll likely have to drill out the old damper mounts and weld in new ones, I think TIG would be too concentrated. With MIG, the puddle could be spread out further and provide more surface area to hold the damper mounts. I'm not an engineer, but if he came to me to fix the problem, I'd fire up the MIG on this one.

Plus, MIG welders are a dim a dozen, so it will likely be cheaper for him. I could do the whole job cradle to grave in an hour or so. TIG would take a couple hours.
