I loved the movie when I viewed it a few years ago.I like how Mr. Munro did All his own work for So many years in his garage,he even forged his own pistons
& kept at it until he got it just right ! w/ the long term goal in mind to "go to Bonneville"
He finally made it there ! and then they told him he couldn't run !
I didn't like that part of the movie..,but it did work well for him in the end
