shercoben12 Report post Posted June 17, 2014 (edited) hi , need to be on a 250 for my age and im on a 2012 300 right now . changing the whole barrel seems a really expensive way to go about it. not gonna sell the bike for another as this one is aswesome. can you get it sleeved down to a 250? is it possible? anyone know anyone who can do it? any other things i could do?!

shyted Report post Posted June 17, 2014 Contact Kevin by email at GasGas u.k and he will give you a possitive yes or no . He will answer your querie and probably give you the reason why if you can't . Alternativly ,you can go on the GasGas uk web site,go to Tech/Spares,look through the on line expandable workshop manual and start by looking at the part numbers for the connecting rod.Compare the 300 & 250 numbers.If they're different id say the rod is longer. So it may not be just down to the bore. Ted. Quote Share this post Link to post Share on other sites

nigel dabster Report post Posted June 18, 2014 which class requires a 250cc? Quote Share this post Link to post Share on other sites
splatshop Report post Posted June 18, 2014 (edited) We have a freshly replated 250cc GasGas barrel in stock http://www.splatshop.co.uk/used-gasgas-pro-cylinder-250cc.html you also need the piston and cylinder head (or just the 250 insert if you have a later bike). As Nigel says why do you need a 250cc, the ACU limit is 125cc for A and B class on a modern bike. Edited June 18, 2014 by splatshop Quote Share this post Link to post Share on other sites

dan williams Report post Posted July 3, 2014 Hmmm late to this party but.... I put an S3 low compression head on my 300 Beta to make it less of an animal. Much cheaper option then a full cylinderectomy. It's a good mod. Keeps the grunt while removing the brutal hit on top. Well reducing it at least.

shercoben12 Report post Posted July 5, 2014 (edited) had so many problems with it , final straw was the top end needed to be replaced on it ( 5 months old ) hardly used like new! was going to do it but the parts took too long ( like months ) and parts supply was shocking... bought A 2012 racing gasser and cracked the frame ... ooooppss. now on a 14 racing. had no problems so far. its in another league riding wise compared to other bikes out there Edited July 5, 2014 by shercoben12 Quote Share this post Link to post Share on other sites
