you need to make sure you use the pull down box to check titles only. thier is only 14 thread with sprockets in their title. you forgot to change search entire posts to search titles only. here is what the page will look like
http://motorbicycling.com/search.php?searchid=7915 thats why this thread should be titled i wish search function was easier to use something like that so the thread could be useful to others as well. these forums are tough to find things and narowing down to title search only makes it a whole lot easier if what the thread is about is in the title
