test. lost first one

 

2nd try so short and sweet. another test today

speedo actual
35 30
6355
80 70

gap increases with speed

 

one more thing. 5,000 rpm at 70mph actual

 

Maybe Honda decided to change the front sprocket down a tooth before mass production without changing the speedo-gears resulting in this delema. I usually watch the tach anyways and not the speedometer.

 

I often wondered whyluck smiled so often when the local HP gave me a passwhen they caught me running 80 +. Then a GPS indicated 80+ was really 77 or so.I haven't counted teeth yet to see if that is what's throwing the speedo off, but will when the stock 17/42 combo goes on tomorrow and the old ones are counted to seewhat I have now. It would be the pits to go out thinking there's a 5 to 6 mile per hour error and find out it has disappeared.

 

bickleboc,
Your readingof 70 mph @5000rpm is the same as my readings. I have a V&H ignition module that is supposed to give more acurate than stock tach readings. The stock module read 12.5% higher.

 

Are you saying there's a good chance Im actually running about 5600 rpm at 70 actual?
If so, this sure is getting confusing!!
