Speedo error with different sprocket sizesgreenspun.com : LUSENET : MV Agusta F4 : One Thread |
AllMy 02 came with a 43T rear sprocket that puts the speedo (and hence odometer) out by about 12-15%.
I have looked azt going back to the 40T rear but the cost is outrageous here in AUS.
The other option was a speedo corrector. Has anyone tried this? If so what was the result? Does the MV have a 2 or three wire speedo (the manufactures seem to want to know this to supply the right unit.
Thanks Darryn

I was planning on keeping my stock 40t sprocket(less than 500 miles),but if you are interested I will take $100 for it. The speed sensor is a three wire system. I have a yellow box calibrator installed but I have yet to get to ride my bike to calibrate it. Curt

Hi Darryn, the F4 comes with 3 wires to the speedo. -Violet/white wiring on bike is switched power with key ON. -Brown wiring is the signal pulse from sensor up to gauge cluster. -Blue wiring is battery negative.For more infos: http://f1.grp.yahoofs.com/v1/wK8TQDalROEYRUfctvPRhx5plqnN1vVKZQWWyfi4y zMu7yZ0_tlEomjI0xJbBiVhtnRS2gDS3StInAyf59A77TjR_Q/Yellow%20Box% 20Install%20for%20MV%20Agusta%20F4S.doc

Darryn,I'll email you the .doc I wrote up on a speedo correction device. It's titled "Yellow Box Install" and is a MS word .doc of about 700KB.
I believe that should be the document Roland is referencing.

But it's just a Yamaha...evryone and their mother has one!

cuervo must be huffing R-1 exhaust if he thinks anyone who thought through buying a F4 would go back to a cheap litre-bike.I would suggest buying the R-1/GSXR-1000/ZX-10R/CBR1000RR before an F4 if your power hungry, and haven't been there already. Good luck converting the experienced!

a R1,GSXR,CBR or ZX10 are cheap but without mechanics problem and more effective in all roadīs and track,i have a F4S and i want to kill this bike iīm very angered !!! and is only a CAGIVA bike not a real Mv Agusta !!!

Cuervo, Based on the topic I'm assuming your speedo doesn't work...?
-- Bill MacCracken (wbmac@yahoo.com), January 26, 2004.
An R1 just doesn't leave the same impression on someone as say an uncorked F4 (let alone a xr750 w. lights & brakes) as you blow by them on the outside of any given corner as if they are standing still.... So many squids & so little time
