The home side were in the lead at the break, but at only 24-15 in front, they still had plenty of work to do.
But Yarnbury ran in 37 points in the second half, without conceding any, giving them a massive 61-15 victory.
Yarnbury sit seventh in the table now, having won two of their first four games.
Ole Rigby, James Daffern and Rossa Daly all scored converted tries before the break for Yarnbury, while Daniel Pound added a penalty.
And Rigby began the second half as he had the first, with an early try to increase Yarnbury’s lead.
He completed his hat-trick after 54 minutes, before a quick brace from Max Lee.
And with Wensleydale completely floored, Rigby scored another two tries to take his final total for the afternoon to five.
He also knocked over a conversion, while George Butler crossed the whitewash too late on.
