Hi Leslie

Yes I understand where your coming from regarding the frame numbers, I am not keen on bodgie jobs.
Its just a little frustrating as I have the original frame with the correct
frame number on it buts its irreparable. The new frame I have is identical to
the old one (besides the number obviously), so technically the number I would be stamping onto the frame would be
legit as I have the original frame.
I am sure my mechanic will point me in the right direction.

My steering taper bearing upgrade kit arrived today, will be much easier than playing with loose ball bearings.

whether your new number is legit or not the old one will be gone.. that's the definition of rebirthing a frame I don't believe there are any technicalities.. it's illegal.

alot of hassle over a GT80 frame. you should be able to find a matching frame and engine for very little if it's matching numbers your chasing.. you're not after a compete bike and wrecks like that come up fairly often.. if you're never going to register it don't worry about the frame number or compliance plate and enjoy it like it is.. sometimes too much stress is put into matching numbers.

I built a YZ80H engine once that had a matching number, nothing was matching other than the one half of the engine that had the number.. the rest was replaced as it was fairly comprehisively damaged.. other side of the case and all.

but that exercise took more effort than just using the replacement engine which would of dropped straight in

Good luck!! and show us some pics of the build

Cheers!
Leslie

Here are some photos of the GT...

A couple of pics taken before the strip



Damage to frame..... I hope whoever welded this is not a boiler maker by trade.


Build so far..




I am painting all of the guards, tank and parts using rattle cans. Have read some good articles and watch some vids on how to do this correctly, so i thought i would give it a shot and save some money.
The hardest part so far has been waiting for right weather, to much bl__dy rain  >:(
The undercoats have come out well. Will try and get some pics up of these later.

looking nice and tidy!! rattle cans are good.. I've done frames with them in the past, good stuff!!

that's pretty rough!! I doubt the numpty who welded that would be a tradie... that frame actually might be salvageable, cut in the right place (on the welds on the engine cradle and just above that engine plate) the frame could be cut and shut with another frame keeping the number from that frame and replacing the damage with the other frames parts, any welding place would be able to do it cleanly and that would solve your matching numbers problem.. you wouldn't even notice it.  ;)

Cheers!
