He read Hydro and Recall, Googled it, now trying to sell it.
If the valve spring caps are shiny aluminum and the adjusters(where they should be) looks like they were snapped off at the adj nut, it has most likely had the LAST fix done to it.
If the valve spring caps are a dark color and the adjuster(where they should be) are smooth and no adj nut, it needs the last fix.
Yes, these unfixed motors are still out there. Been 3yrs since Guzzi made a batch of kits that I know of.
Been 10yrs since those Hydro's were made and the final fix.
I would go to dealer w/VIN like Bruce says.
