Thank you. I've been keeping the rides short because the Whizzer isn't really "broken in" yet. Less than 200 miles on it in 10 years, it sat neglected on a back porch since it was new. I'm finding crusty rubber, oxidized paint and dry joints and bearings. I've got to ask Quenton about whether I can hog out the restrictor plate. If I read correctly, he said nothing should be done on this WC-1 engine. I am thinking that cleaning up the exhaust and intake is OK though.
