I have an 07 classic with 29k on it. A new secondary tps was installed with 19k on the bike in oct. 2010. the bike has ran and started perfectly since then. Now, when i start the bike, it idles at rough 650 rpm with no increase in rpm. If I turn it off and then start the bike right away it starts like it always has (revs to about 1000 to 1200 rpm and then settles to an idle of 850. I have watched the stepper motor when i turn it on and it seems to work ok. The piston pushes out a little and then the piston pulls back toward the stepper motor a little. As I said , when I start it for the second time it idles perfectly(850 rpm) and runs great. I only have an issue with it starting the first time.
