thanks honda rs , i will pass on this knowledge to my mate ,looks like he is going to be busy tonight !.cheers, and all the best for the new year.

Hello All

My son's 280 TXT has got a fair old rattle on it ,so I rang GASGAS UK today for a price for a new piston, are we all sitting down?

That does seem steep, I seem to remember the 2002 Pro 280 piston being about

I am going to whip the top end off in the week,hope is just the piston
