So I changed the back tire on the V7 last weekend, commuted all week without any issue, then a 3 hour ride to Lake of the Ozarks bike fest. and farted around a bit up there... (and yes a spirited launch or two)
When I can out of the restaurant after dinner, I have a flat.
Well crap....
Long and short, is I did this myself, I have put 100 tires on the dirt bikes over the last 30 years and never have any issues, but those come with rim locks, Not so on the Guzzi.
So, the thing NOT to do is the thin film of grease to help the bead ease onto the rim, unless your bike is equipped with rim locks !
