Thanks for all the advise everyone

Hi Piston kit from Ebay, http://cgi.ebay.co.uk/Wossner-Piston-Gas-Gas-TXT250-01-09-Sale-Price-/380297828362?pt=UK_Motorcycle_Parts&hash=item588b84580a they have three sizes and I got the largest 72.49 which was pefect for my 2003.

Having finally got my barrel and wossner piston checked for fit it's time to re-assemble. Should the new small end bearings be lubricated with anything before assembly and what are the correct barrel and head torque settings. Also I was told the fit was a good one but to run it in carefully, should my fuel mix be on the slightly rich side when doing this? thanks

Hi Jon there is a "B" on the piston head, I am guessing that I am going to be safe with the middle size, thanks for the info Mike

I am re-building my 2003 Gas gas 250 txt pro and phoned GasGas uk for piston rings, I was told that they can no longer be supplied as there has been a change in the piston manufacturer and I would need a whole new piston kit at 120 quid. I had been looking at a Wossner kit on ebay for under 90 quid, they advertise it as a better replacement... is this true? they also say... and I quote "OE bore size is 72.47mm. Pistons available in 72.47mm, 72.48mm and 72.49mm. Please specify which is required when ordering." I have been told if I go for the middle size I will be OK but Wossner say I should take the barrel to an engineer to be measured (too much hassle) Any advise would be great. Thanks
