Howdy people,i'm wondering if anyone can give me some advice regarding big bore kits.I currently have a nice wee xvs 125 with low miles and sound engine,but thinking about trying a BBK.If anyone has any experience with these and are aware of where to get one and costing it would be much appreciated.Thanks guys.

i dont think you can get one for the xvs 125 but have a look for a bbk for the XV 125 virago

cause the cylinders are exactly the same but you will need to sort out the timing on the heads, but they bolt straight onto the xvs 125 bottom end as to where to get them from i havent got a clue but normally ul find that the bbk reduces reliability quite a bit and can sometimes cost more than a new engine so shop around.
