Just got back from a trip on my new-to-me 04 950 ADV and got terrible gas mileage..also noticed the idle hung out at 2000 rpms before dropping back down to 1400 rpms. Sometimes it would need to help it get back down by slowing way down while still in gear to bring the rpms down. Also, I get a strong exhaust/rich smell from the bike. On each tank, I got to around 130 miles before the fuel light would go on...terrible Its got a 2 to 1 mod, now stainless remus revolution w/ spark arrestor in palce (yeah, I'm the guy who just posted about the smoked carbon remus a few days ago), ContiTrail Attack on RR, Scorpion up front. I was running with the Gobis on and we averaged 80 mph. Did initial research on the site/google and saw guys mention to check for vaccuum leaks and ensure the carbs were seated properly, etc. I'm gonna tackle that first thing tomorrow morning. Question, does a vaccuum leak or poorly seated carb lead to poor gas mileage or do I have something else going on? Thanks in advance for your replies.
