I have been hanging around this forum for a while, reading, reading and more reading and I just want to thank all of you for saving me lots of money on a new bike. My '04 Savage had the backfiring/low power problem and I was becoming very frustrated. I'm not very mechanical so I tried some mods and quickly found out I was over my head. After asking around I found a mechanic who would do the white spacer and the idle screw adjustment. Wow!! What a change! I just brought it home and it's like a new bike! I downloaded parts of your discussions and the carb pics to help the guy and I guess it really did.
Thanks again folks. You are the best!
