Default txt 2000

Hi all,i am newto the forum, i recently had a beta , sold it and now have a txt2000.
when i first got it i thought ill clean the carb, change the fuel, give it a check-over, instead i did none of the above and took it out, the carb stuck open and it seized..... MY OWN FAULT!!!! i have stripped the bike,consulted youtube, taken the barrel off and gently knocked the piston through, i havenow cleaned up the barreland the piston, and need advice for the following:
Do i buy a new piston then take it with the existing barrel to get matched?(the piston looks in bad shape,there is a local place ive been reccomended)
Which piston do i buy?where isthe best place to buy piston & gaskets?
my bike serialnumber is: VTRGG250002000562*
is it a 250cc txt year 2000?
Also there was loads of mud inside the airbox, the seal doesnt seem great, is
this common?

i hope you guys can help me......... then i cant get it bck together!!
Dan

Regarding parts in the UK I would try http://www.trialendurodirect.com/ which is the online shop of Gasgas UK if I have understood matters correctly.
I suggest you buy the piston first and then get the cylinder repaired to match the piston.
Regarding frame number I don't know.
If you suspect dirt has entered the intake I would also consider checking the main and conrod big end bearings. Not fun to rebuild the top end just to learn as soon as you start it up that the bottom end bearings are shot too.
Do you have any idea on how many hours the engine has ran since last rebuild?

Should be a plated barrel, so what is condition of the plating? Ally smeared on needs to be removed carefully. The barrel will have a letter stamped on it for piston size originally fitted but best to get it measured by savy 2 stroke shop. Heaps of small adds if you pick up a classic mc mechanics magazine in the shop.

Thanks for the info, think it was a straight forward seize, don't want to split the case at this point, but will do the con rod bearing at same time, taking barrel to engine shop for advice,then order a piston.thanks for the help👍👍
