I have a WR450 2008. I planned to do the free mods only to find the AIS removed and blanked, the baffle removed from the exhaust and a throttle stop screw approx 30mm long in the bag of spares I got when I bought the bike second hand. So, I checked and can see the grey wire is still attached . If I disconnect the grey wire do you think I will need to re jet etc or do you think I can take a chance and figure it's been done by superior powers of deduction? Any thoughts on this would be appreciated.
