first of all, welcome pisceschick, we've seen a couple posts from you (3), we'll assume you're another of our lady riders, we have many here, including my wife. introductions are welcomed and encouraged, what part of the savage world do you call home? anyhow, we're glad to have you aboard.

secondly, we dont rip people on this forum, which is why it is such a fine place to spend a few minutes of our busy lives. encouragement, be it mechanical, rider skills, or personal, is the norm.
thirdly, as has been mentioned, the backfiring is normal ??? for a stock S40/savage, YOU aren't doing anything wrong. it is fixable, it is well documented and practiced throughout this group, and we'll help, if & when, you're ready.
