Petrol tank

i have full tank of petrol in old bike but after someone try to stell bike key not working anybody know how to change key lock from tank ?

Think you will have to take the whole silver assembly off, if you want to get the petrol out, let it drain through the fuel tap.

I seem to remember there are two screws holding the locking mechanism in place, you need to get these out to get access the lock barrel.

On some Yamahas (not sure if it applies to the Thundercat, but it certainly did on the XJ900S that I had) one of the screws holding the cap surround is actually under the cap, presumably as a security measure. Which is a b****r if you can't open the cap!

i got info from other forum. there is no way to take cap off without key :(

You got nothing to lose, try taking off the whole cap assembly by removing the Allen bolts. The workshop manual don't show anything about the cap, so no help from there.

You do need to get underneath the cap to get to the lock mechanism.

What is happening when you try the key? Does the key go all the way in? If so is the problem that you can't turn it?

thief try to drill ignition and tank i don't know why so key is useless

If the barrel has been drilled the lock is knackered anyway but the drill will have probably softened up the insides of the lock. You've nothing to lose getting a big screwdriver in the lock and forcing it open.

Are you just opening it to replace it or is there another reason??

Otherwise just drain the fuel from the tap underneath as Steve said

i dont know what to do
sell it for part?
sell it like it is?
i will like to repair but have no money :(
