Hi all
Was wondering if anyone else has problems with the speedo readin incorrectly, I was out the other day on the mc 21 got to a long stright`ish road, and rember looking at the speedo which was flickering around 90 mph, just before I slowed to turn at a junction.
Anyway wen we pulled up the dude behind me (on a cbr 400 triarm) said before i sat up to slow I was pulling away from him and his speedo read 110mph.
Should they not read closer readings than that like 5 mpr differance not 20mph
an nsr pulling away from a cbr,sounds like stephen and monkey at a trackday .The best way to find out if the speedo is working ok is to follow a friend in a car and get them to signal to you at 30,40 and 70 .Most modern cars dont have a cable drive to the speedo they run off a sensor in the gearbox so are pretty acurate.
I may be completely wrong but on the 21 and 28, as the drive is from the gearbox, if you have a non standard sprocket (standard 40T on the 21 and 44T on the 28 i think) then the speedo will be out... _________________ NSR300R - Why did i ever have a 250...
but I forgot to mention that if you've got time to look at the speedo you're riding too slowly anyway! _________________ NSR300R - Why did i ever have a 250...
Check that the drive to the speedo isn't worn - the parts are plastic and obviously wear over time.
Secondly, check the cable is free to rotate in the sleeve (with it removed). If not, get some lube down there. _________________ MC21SP Plaything
