False...
If you take a high performance motor and run it at low rpm's without ever getting on the throttle, carbon builds up. Same effect...that carbon that builds up isn't noticeable for hours and hours from the outside but over-time that TINY residues BUILDS UP. We've had so many blown motors come through here in the last year, I'd be willing to bet I could guess what kind of air filter is run on it by carb and intake condition. Run a controlled lab experiment, those particles aren't so small
But instead of referencing a poll from a bunch of yahoos, why don't we get a new poll started from ground zero on here and see what our members really prefer
