I bought my scura with 9600 miles and have put 1k of my own on it, and as far as i know the previous owner hasn't had a problem with the shifting. I'm curious as to if i need to check my spring and boss. I have the service manual so i'm not that worried about the work. What i would like to know is if I need a new gasket or if it is sealant on the side cover. Thanks for any info guys.
