Oh I'm not going to run without an air filter. I'd like to try it without the snorkel some time but I'm not taking off the filter. If I drop the snorkel I'll throw an oil-soaked green pad over the top of the filter. I think some bungee cords ought to hold it down.
I'm fully expecting to do a 'Fred Special' and hose clamp a split inner-tube around the intake boots.
