wruffit Posted January 13, 2013 Report Share Posted January 13, 2013 Hi folks, I've got an 08 300 TXT Pro according to the frame number but I noticed a casting mark on the barrel which states GG25 so do I assume it is a 250? Can you check your bikes to see if this mark has a purpose? Thanks Quote Link to comment Share on other sites More sharing options...
laser1 Posted January 14, 2013 Report Share Posted January 14, 2013 It seems someone did a conversion to your bike. Yes - GG25 marking on the jug,adjacent to the exhaust, means 250cc. Quote Link to comment Share on other sites More sharing options...
NAD1 Posted January 15, 2013 Report Share Posted January 15, 2013 Are you in the UK? If so check with Gas Gas UK who can tell you what year / engine bike you should have based on frame number etc. If not UK the relevant GG importer for that country will be able to do the same. It is possible the 300 was to powerful etc for previous owner - have you contacted them? - and they changed the engine out for a 250cc.
