can you be a bit more specific? that might help in the answer/suggestion department. if the crank is shot, about $1200, if the case is shot, tack on another $700. rods, bearings, misc gaskets, not much. labor depends on whats done. you kind of asked an open ended question, so its hard to pin a price tag. just a cylinder problem would be cheaper. sleds are sleds, not that much difference in the bottom ends.
