Willie Posted May 7, 2006 Share Posted May 7, 2006 Last month a buddy of mine called me up and said he just got done adjusting the valves on his '04 RT and was wondering if I could synch his TB's for him. I say, no problem come on over. Anyway, he got here and his bike is idling at like 800rpms. BBS are only about 3/4 turns out on both sides. I furged I just start from scratch and set them both at 1 1/2 turns out. Fired upo bike and it idled right at +- 1050rpm. Cool! A little fiddling got it centered on the twinmax at idle and a small twist on the one cable centered the needle at 1500 and 4000rpm. I test drove the bike and it was awesome. Well, I just saw him tonight. After running 3 tanks of gas through it, he is at a consistant 5mpg less than he was before. He aslo said that he was looking around on the bike and found that one of the lines was off his charcoal canister. He said he adjusted the valves toward the tighter end of the spectrum meaning there was a bit more of drag on the feeler guages when he was done. What would cause the drop in MPG? Having the BBS out farther than before, hose of canister, valves adjusted a bit tighter? I told him I would post this on here and would get an answer for him. Thanks, Terry Link to comment
