Hopefully fitting my clocks this weekend..

can someone clarify if CBR speed sensor works from bolt heads, or must it be magnets?

If im using a speedo healer, can i run it from the driveshaft as oppose to the prop?

thanks

I've used my speed sensor on the prop to diff bolts and calibrated with a speedo healer.

So far so good it work really well. Not sure about the CBR, but most sensors detect a magnet field. So either steel bolts or magnets will work.

Plenty of threads on here with useful tips.

Sorry, you used it on the diff or the prop?

I did have a search, couldn't understand why people are using magnets if not required..
