Altering odometer on '93?

[Macrobb]

You really do want to look at the heads though... Make sure they aren't in the (replacable, always crack) precups only.
Otherwise, you'll just be wasting a lot of money on a new set of heads... which might come with their own problems(does anyone even /make/ new IDI heads nowdays?), for no reason.

No new heads have been made in years. These will be rebuild heads
