You're right, I know two different Bonnie riders who's bikes wouldn't run in the spring. Seems a family of mice were nesting in the air filter. They had both removed their snorkles.

I installed a Jenks velo-stack on my Thruxton, rejetted, installed uni filter and predator pipes. WOW! Now that it has been confirmed that they will install on my America I think its a GO.
