Rushed reply:  Any options on filling up the drilled out fatsos (JB Weld?) and re-drilling original dia?

this is the disadvantage of powdercoat...welding em' up is gonna be difficult

Machine a thin hat bushing .. Head need only be about 10 thou thick... Aluminum.... Then drive the rivets in..

Have no skill or equipment to do any machining, but this gives me an idea. I should be able to source a flat head rivet in small shank dia locally, then drill through the head to where the original rivet will grip hard, grind down the head super thin. Rivet goes in frame, VIN rivet goes into the base rivet. This should ensure a good bite without loss of visibility on the lettering by big dome head rivets.

Rafi,
One thing that comes to mind you could do...use my nutsert tool.  You drill out holes the proper size in the frame.  Use the nutsert tool to snap in pop rivets that are threaded.  Then you could use screws to secure the VIN plate to the frame by screwing into those threaded studs.  After the screws are fully tightened, file down the top of the screws to make them look smooth like rivets.

I'll loan you my tool if you decide you want to go that route...just PM me if you do.  Check to make sure the sizes would work for you first if you do.  It comes with mandrels for 6 different sizes.  Metric M5, M6, & M8 and in SAE 10-24, 1/4-20, & 5/16-18

This is the tool I'm talking about.

That is a neat tool!

The rivets in the VIN plate are much smaller than an M5, more like 1/8" rivets. I'd avoid using screws ground over as the possibility for a Police inspection of the VIN tag later during a sale could uncover a molested/altered tag and invalidate the transfer/vehicle. VIN tags are finicky things in different states... Best to use rivets and if you must fill the frame to install correct sized rivets, do so. Then drill appropriate sized holes in the filled metal.

Cal, no offense intended, but you sound really paranoid about this VIN tag install!

If Mo has a title, why would a cop inspect the tag during a sale?? 

[calj737]

No paranoid, just burned by it before. And as I said, "it differs greatly" state-to-state. If he sells the bike, out of state, some states require an inspection of the vehicle and any cop looking at the altered tag can bring the whole shebang to a grinding, screeching halt. If the buyer is another state, paid money, shipped/picked up a bike, then gets jammed up, who is at fault? The buyer would have recourse against the seller (Rafi). I'd hate to see him in that predicament simply because of his OCD over a detail that is critical (legally) but insignificant (operationally).

I take no offense, Stev-o, its a legitimate question and I know I already posted a caveat about it. I hate to see anyone suffer the same #$%*e I had to deal with. Everyone is offering good ideas to help him out, but some ideas have consequences depending upon future circumstances. Thats my point.

Rafi is like the son I'll never have...

[Stev-o]

I had a feeling you may have had a personal dealing in this. 
In TX, cops dont typically inspect VIN's for inspection purposes, we have inspection stations.

[calj737]

Yep, and it was buying a vehicle from TX that burned me!  Not your fault though, so I still love you, Stev-o

[edwardmorris]

@Ron, thanks for the generous offer, but I'd like to give Frank's idea (or my adaptation of it) a try first to avoid drilling even larger holes in the frame. The stock VIN rivets are actually smaller than 1/8, probably 1/16 at best. I'm going to check out my local Ace Hardware for short length smash rivets in the smallest size they carry, probably 1/8. The PC shop has drilled them out to 7/64, a hair under the 1/8 so hopefully with no more than a small widening 1/8 rivets will bite. Getting the stock sized ones into these should work out OK after that. And all of it gets concealed nicely. Worst case scenario is that I stick with the smallest rivets I can find and live with a letter or two getting covered up. Hardly matters as the actual VIN is nowhere near these areas.

@Stev-o Both my bikes had out of state titles and I did have to call the cops to come verify it. They weren't particularly picky but they did make sure the neck stamping matched the tag and the tag looked unmolested. Other state, or just another cop may not be so easy, so yea, Cal's caution applies. And I'm sure he meant I'm the son he'll never want

[SOHC4 Cafe Racer Fan]

In California, when importing an out of state bike, even AAA has to check the VIN stamp AND the VIN plate, as well as the engine serial number.

I better stay in the wild state of Texas, I'm not too good following all those rules and regulations!

I better stay in the great state of Texas, I'm not too good following all those rules and regulations!

I mean, this is a state that feels the need to have their own bikini team.  God bless Texas!


Sorry for the threadjack.  Back to the build now.  Great work so far, Rafi.  Really enjoying this build just like I did with your other one.

[calj737]

Dang Ron, raise the bar on building something! I'd love to see a restoration of ^^^^ that quality come out of Rafi's garage 

[Davez134]

^^ those parts are way more expensive, and way mor maintenance than every 3000 miles

[calj737]

I wouldn't mind get greasy in that garage. Sorry, Rafi, the adoption is off  I have suddenly found others more deserving of my inheritance

We do!  My buddy Tom use to travel with them to the Bahamas where that pic ^^^ was taken! I have an old calendar around here somewhere [where the wifey wont see it]

[calj737]

BBQ, Open Carry and a Bikin team!?!?! Move over, Brother, I'm on my way!

[edwardmorris]

So I got a call this afternoon that my stuff was ready for pick up at the PC shop. Made my way there on the way back home, good ol Bob was in and happily showed me the completed head which he did himself like the rest of the engine. Pulled up a large box full of my parts, so I reached in to unwrap one and check it out. To my utter disappointment, it wasn't Black Magic, it was Paccar Black.

Me: Bob, this isn't black magic, this is way to shiny.
Bob: The guys did what you asked on the work order, weren't there some pieces that were paccar and some black magic?
Me: Yes, three pieces were paccar, rest were black magic.
Bob: It will take a special kind of stupid to screw up such a large order, I'm sure its in the order form.
Me: Well Bob, I hate to tell you, but I think that stupid works for you.
Bob: Let me look at the work order here...

I was pretty pissed and about to let out a scream, then I noticed poor Bob was embarrassed and outraged at the same time. He just said, I'll redo them myself, lets write it up again. I just wanted to avoid anymore screw ups and said just make it all black magic, no need to redo the three. So I guess, I'll have to make yet another trip or two, but on the bright side it won't be redone by staff. Obviously I'm not going back there unless Bob makes the time to do everything himself (doubtful). Its much less hassle to load it all up on a truck and drive down to GA to Powderman.

At least the head is done and ready to leave for JMR's. Some of you (at least one of you) will recognize this head, it once belonged to Bill's calendar girl.

[edwardmorris]

The pieces they got wrong, at least they turned out nice. Just need to touch up the threads on the oil tank with paint.

[Restoration Fan]

Given the issue with the VIN plate and now this, I can't fault you for your disappointment.

Look on the bright side.  If you just bring the next one down to Mark, you're literally less than an hour from Bill's house and my house.  You can come hang out with the cool kids in Atlanta while Mark works on your stuff.   

[Bill/BentON Racing]

+1, don't give some azzhole a reason to take your bike away...on a flatbed wrecker on its side!! Bill

[calj737]

I'd leave the threads bare, use some lubricant when installing, and be done. Paint on the threads only bogs up the joint.
