#442171 Roadstar_Rob (User) Junior Boarder Posts: 132 RoadStar RPM's?? 5 Months, 3 Weeks ago   I've searched in vain trying to determine what RPM's the RoadStar is churning at various speeds. I have a 2009 all stock RoadStar and just installed my Barons tach and although the instructions state the single fire adapter is required I was getting very high RPM readings that just didn't seem to be correct. I just bypassed the adapter and have my tach green wire going directly into the front coil negative terminal. I get the following which I suspect is accurate but wanting to confirm. AT 2000RPM I am getting the following MPH on the speedo 1st gear = 18mph 2nd gear = 28 3rd gear = 38 4th gear = 47 5th gear = 57 I realize the factory speedo is off give or take 5% but are these readings close? Thanks!

Your speeds are correct.   Logged     My Site Black Ice is Shiny, Black Ice is Deadly, Ya Wanna Ride My BlackIce?   The administrator has disabled public write access. #442203 Roadstar_Rob (User) Junior Boarder Posts: 132 Re:RoadStar RPM's?? 5 Months, 3 Weeks ago   Thanks. After installing the adapter per the now known to be incorrect instructions (thru 2007 don't require/2008 and up do require) to both coils (that 2nd coil under the tank was fun!) and way too much time spent trouble shooting I'm just glad to get it finally working correctly. It was also bouncing all over the place and now its dead on accurate with no bounce whatsoever...   Logged     2009 RoadStar   The administrator has disabled public write access. #442213 Stocked (User) Wayne Platinum Boarder Posts: 1221 Re:RoadStar RPM's?? 5 Months, 3 Weeks ago   You're readings seem pretty much on with mine but I still get the bounce, usually at idle. I know when I am running on the highway in 5th at 75-80mph i'm hitting 2500-2800 rpm   Logged       The administrator has disabled public write access. #445628 starjak (User) Fresh Boarder Posts: 11 Re:RoadStar RPM's?? 5 Months, 1 Week ago   Curt wrote: Baron's tach you don't need the adapter I am running two of them and no adapter.

When my speedo shows 75 mph I am only running 69 mph on my gps. That will change your RPM by as much as 200 if you take it into consideration.   Logged     The administrator has disabled public write access.
