Where? I only saw 2 places NECK and front of ENGINE CASES....Where else are there numbers?

 

i dont exactly know but there are other places they can acid test to get them on those frames. thats way 636's are one of the only bikes on www.ronayers.com that do not tell you where they are.

here is the f4i from ronayers http://www.ronayers.com/fiche/200_03...30&parent=5220

 

well then just heat it with a torch or tig and reset the molecular metal grain.

 

yeah, but to get everything you would then be plug welding not filling and your **** is definately going to look suspicious.

 

::with lots of sarcasm::
i guess reading my short post in its entirety is out of the question ?

 

I dunno man I have a bare 06 636 frame right infront of me, and just looked at it 100 different ways and can only see the one VIN # on it....

 

that just tells you 1 place where you can find each one at. arent all the numbers different? ie engine, throttle body.......

they only stamp the neck with the VIN.

i call BS on bein able to do the acid test from the backside. its not physically possible. i KNOW its possible from the top side. if you were to ground down like a 1/4 inch, theres NO WAY possible to still pull up the numbers.

when people restamp the numbers in, they usually just ground down just enough to smooth it out and restamp the new numbers in. that not enough. but sayin you can still pull the numbers from the back of the neck?

 

thats cuz they ONLY stamp it in one place!!! that link only shows 1 spot as well.

 

by the way, so youre tellin me they cut the neck in half to do the acid test from the backside???? or crack your engine case open????

so what happens if theyre wrong? they buy you a new frame or motor case? NO!!! cuz they don't do that!!!

 

it depends on the thickness of the material, i will try to find a better picture to give you a better idea.

 

there are supposed to be hiddin vins on that frame where they can test it easily to get the numbers along with those motors. i have a friend that works at a kawi dealer and he has seen them pull the numbers off the frame and not at the neck.they do the insurance estimates for wrecked and theft bikes. bieleve it if you want. i dont care. just do not get caught down in florida with hot **** or you will be gone for a while

 

this is not B.S. i have recieved proprietary info and there are hidden vins on a frame.

 

and the 636 motors as well

 

Im with you on this! I think the acid test would only work for idiots that only grind down untill the numbers are gone...I just cant see the numbers transfering through more then a 1/4" of cast aluminum....I'll believe it when I see it, so again if anyone knows more info about his "acid test" please post up. Id like to try it...

 

do some research on the forging process, it will give you a better understanding.

 

Id like to believe you but to me seeing is believing, and I dont see **** other then the one VIN on that frame...Ive also got freinds that work at dealers aswell as a buddy that works at the Kawi Canada warehouse. And they are all laughing at these supposed hidden numbers...

So like I said I'll believe it when I see it, and this 06 636 frame is junk so if you can tell me where these hidden numbers are. I'll cut the thing in half if I have to just to see them....

 

I dont have too I already know a pretty good amount about forging, casting, etc etc. For one forging has nothing to do with punching VIN numbers, they are not even close to the same thing..

Im not doubting that when you punch numbers they penatrate past the number itself deeper into the material, i fully understand that....I just dont see that penatration going deeper then a few mm's.....And I call BS on it showing up from the backside of a 1/2" think cast part, not with the size of the numbers used for VIN's...These numbers arent punched with 10 ton punch press....

Ive been wrong thou, so like I said Id like to try this myself.....I think that if I only grind till the number is gone it will show up, but if I remove 1/4" I dont think it will....

Think of it this way.....You have a pad of paper 100 sheets thick, and your write something with a pen. Sure it penatrates through a few sheets of paper, and you can see what was written....But it doesnt go through the whole ****** 100 sheets and through the back of the pad. Only tear off a few pages and you can still see what was written, but tear off enough sheets and that **** is as good as gone....

 

actually they are pretty similar because you are forcing the grain to change it location and pattern.

i dont know about 636's, but f4i's are 3/8" at best in the neck area

 

i said it depends on the thickness of the given material, also paper is not solid like metal

 

Ok its not exaclty the same but you get the idea, there is a point in every material where that transfer stops and you cant read it anymore....It only goes so deep is all Im trying to get at.....I know Im right about that cause you cant tell me numbers are going to show up through 2" of material right?
Id just like to find out how deep they will show, maybe on some bikes theres not enough thickness so no matter how deep you go grinding its not enough to elimnate it completely. Now on motors there is usually a pretty think area where the numbers are, Id say at least 3/8"-1/2....

Now if someone could just tell me what kind of acid they use Id try this out and wed know for sure....Ive searched it and cant seem to find any info for this "acid testing"....Maybe theres a better name for it?
