thats your secondary wrap, with a yamaha spring you add the two numbers multiply by ten and thats your degrees of wrap. some aftermarket springs have the tab locations different so that formula doesn't work. if its a hauck spring start with their suggestion, if its a yamaha spring thats too much wrap
