Making frame number clearer

Postby asterysk_usa » Mon Nov 04, 2019 7:03 am

My frame number stamping isn't very deep. I'm going to mask it during blasting and use old fashioned paint stripper

Any suggestions on what if anything I can do with it before priming and painting to preserve as much detail as possible, I was consider getting an engraving tool and making the stamping cleaner but am wary

thx

dont tamper with the number and try and make it deeper. Just scrape out the paint with a scriber and dont put too many layers of paint in that area. When painted, if you need to highlight the number, rub in some chalk dust.

If a number appears to have been tampered with, it will not be considered genuine.

Maybe you are already aware of it, but this is very important since if you intend to ride it in the U.K., and assuming it isn't on the Gov't (DVLA) records you will need to obtain a Dating Certificate from the Club's factory records in order to register it and obtain an age-related registration number. You will have to provide this club's Dating Officer with a clear photograph of the frame number. The frame number is the official proof of its identity which is acceptable to the DVLA. The bike when complete will almost certainly be subject to inspection in order to verify its authenticity which will fail if the frame number has been altered, enhanced or tampered with in any way.

I expect other countries will have similar requirements but you'll still need a Dating Certificate.

This is very useful to know, thankyou. Once I get the paint removed I will take a photo and send in for the certificate (is there a similar thing for the engine ?)

The scriber sounds like an excellent idea, many thanks

You will have to declare the engine number when obtaining an age related registration number and it will appear on the new V5c (registration document) but engine numbers can be amended at any time. Engines are/were often changed.

I now have a very clear frame number after blasting, have asked the paint shop to mask the frame number before they powder coat with epoxy primer . This then leaves me with the decision on what to do with the bare metal around the frame number so that I prevent rust but keep the stamping very clear, open to any suggestions

Also, as I researched the dating options form the club I saw mention of a gearbox serial, could someone kindly advise where this should be located on a Burman

If your gearbox has a number it will be on the top edge around where the clutch cable enters.

if it ain't broke don't fix

I searched everywhere but can’t find any number. Am I correct in assuming that the gearbox serial was optional when the bike left the factory
