How? The area where the VIN is punched on my 636 frame is 1/2" thick. Are you saying the punching process thranfers all the way through 1/2" of cast aluminum? And also to even be able to see the other side you would have to cut the frame open....

Im interested, doubtfull, but Id like to see it

 

i do not know what kind it is but it works

 

***** i hate to do this to you, but yeah punch yourself in the face

 

yes it transfers all the way through on the neck. they bust alot of people every year at the hess station in daytona. they do it right in the parking lot infront of everyone. do not ride dirty stuff in daytona at all

 

sorry i just woke up

but they can do it from the front also

 

yall do know ne1 can read this shizzle right... ...its nothing for a 5 0 to see this **** in your hood and start an investigation on yo ace.....and even though your frames wasnt stolen, grinding the numbers off was still a felony

 

i dont care all my stuff is clean

 

Now that I gotta see! If anyone knows more info about this acid test, what kind of acid Id need and how its done please post up....Ive got a few things Id like to try this out on

 

i did a lot of foundry work when i was younger and it has to do with the grain in the metal its hard to explain but this picture should help


when you stamp metal you are changing pushing the grain around (picture b), yes you are only stamping the surface, but its pushing the grain around far below the surface. grinding, filling, and restamping works well, but you must be sure to do the back side too, because with thin material it will push the grain around all the way through. if you need more further detail just ask.

 

isnt it like 4pm in florida? rough night?

 

holy **** on what grounds can they do that, unless they have a warrant how do they start pouring acid on peoples ****

the acid test is 100% true, my buddy was arrested for selling a blank race frame, and 2 years later hes getting arrested because there were numbers underneath it. he saw the numbers during his court hearing, and they were plain as day

 

good work but yes it has to do with movement in the metalgrain

Haha yes

 

Also if you guys are saying that this acid test relys on transfer from the punching process, then it will not work on newer bikes the the 06+ R6 because those VIN are noy laser etched not punched....Right?

 

some are so dumb they can even find the numbers anywhere

 

they just run numbers at hess. undercover cops just walking around running numbers if they look not so stck at all or no motor numbers your **** is going with them for furthewr testing

 

but you all do know that there are like 4 or 5 locations on the 05-06 636 motors and frames where they can pull numbers from acid testing

 

That makes perfect sense and I know that happens with any # stamping, but how deep is the grain affected? I just dont see how stamping numbers 1mm deep with transfer though 1/2" of cast aluminum....A thin sheet of aluminum or a steel tube frame yes, but a 1/2" cast neck?

 

Stock05- You are completly correct on this one. The material will fatigue under a stress of a stamp. Grind down past the numbers and it will show trace of the previous imprint with the dye/acid, because of the stress risers created from the inital stamping process.

 

Okay, so go get a bike and grind down the numbers and have the police acid test. Let me know how that works out for you.

 

my schedule is switching to 6-10's in january so hopefully in february i will be back out that way
theorectically speaking yes because now you are melting the metal, but i dont know how deep the laser penetrates and you are still disturbing the grain pattern

mexicans know this, but i just avoid hot parts and as of late ive been avoiding bikes altogether
yeah, im ******* awesome
