Most have had dealer fix, or fixed it them selves. wiki has co mod for the ECU that has cured most that I have heard of.
And Like springer stated, the nut on the pulley either blue loctite or stacking the nut, fixes that.
Sorry got in a hurry or I would have done the same updates to my older model issues. All can be fixed if it runs and the price is right. should be able to enjoy the **** out of it.
