[millesteve]

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

bbpower.de also tune and big bore them

[r550s]

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.
