HI does anyone do a big bore kit for an 04 bcr, or would it be posible to use r1150 bits to give my bcr more CCs

r1150 barrels will not swap straight onto the 1100s crankcases - the spigot at the base of the barrel is too large. I don't know whether san jose turn down the spigot on their barrels, or bore out the crankcases - but there's machining work involved, hence the price.
