A few?
How many Division 2 races did you and Brenda skip this year Bill? We didn't make the tour this year, we'll be back next year.
We have never broken a rocker arm, not in 6 years, although this year was real short. We've broken one 7/16" rocker stud, the poly lock killed the entire engine, including the block. We have only run near 500 passes on one set of rockers, and maybe 300 passes on the other set. No, we ain't as fast as some, but we haven't lost too many heads up races, we've got 2-3 class wins, and we usually go a few rounds fairly often. It may not be a rocket, but it ain't a slug, either.
