bennyboy1 Posted September 8, 2012 Share Posted September 8, 2012 From what I have read would I be correct in assuming these barrels will fit onto my 125 drag, which should give me around 190cc -- 200cc. http://www.ebay.co.uk/itm/220661462441?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2648 Link to comment Share on other sites More sharing options...
Moderator DirtyDT Posted September 9, 2012 Moderator Share Posted September 9, 2012 They are very cheap.It would give you around 250cc as it is a 250 kit. The assumption s would all the ancilleriries from the 125 fit them. Engine and head bolts would need to be the same. Cam chain position and length would need to be the came Exhaust outlets would need to be the same Manifold inlet would need to be the same Also The carb would need to handle the difference The coil(s) would need to handle the difference The CDI would need to handle the difference They would need to phyisically fit in the space Apart for that it could be plain sailing. Has anyone else done this? Have a look here LINKY Link to comment Share on other sites More sharing options...
bennyboy1 Posted September 9, 2012 Author Share Posted September 9, 2012 I am actually planning to get my barrels rebored, but found these while nosing around, had never thought of the cdi I have found a place in glasgow who will rebore and supply pistons and small ends to match, he cannot tell me how much he can take off without physically seeing them. As far as i know you cannot get big bore kits off the shelf for the xvs so that is why I wondered about 250 barrels when I seen them. I am not looking for a flying machine just a little bit extra to keep the speed steady when I hit a hilly part PLAN B IS USUALLY BETTER Link to comment Share on other sites More sharing options...
