Todd,
It's a real pain in the ass. That's why I don't change them very often. In the early spring I have the street tires on for some low speed road tests. I put the slicks on for the first event in May and if I don't blow up my engine in October then the Trigos go back on.
BTW The slicks are still on.
BTW II Don Durner ERA bolt on w/ slicks
Paul Formanack ERA bolt on w/ slicks
