SV flywheel rotor lightening
2 Attachment(s)
One for the techies here... I'm interested in lightening the rotor flywheel on my K5 race bike as done by Spears Enterprises in the US. A friend of a friend has a lathe and a method of balancing the flywheel. Anyway, here's the problem...
As can be seen from the pics there are raised lugs and a small countersunk 'dimple' on the outside of the flywheel. The crank position sensor incorporates two pick-ups, both with their own separate wire(s), one a single metal bar which reads the lugs and the second a twin bar which presumably reads the dimple. It has been suggested to me that the dimple is for balance but, as the lightening involves machining the flywheel back to the lugs and no more dimple, I need to find out what this second pick-up is for. Any gurus out there can shed the light? |
Re: SV flywheel rotor lightening
who told you it reads dimples?it does not,only lugs.
if you taking magnets out you can cut it all the way up to lugs. |
Re: SV flywheel rotor lightening
The fact that the second pick-up in the sensor, which is aligned with the dimple, and with it's own wire, leads me to believe that it has some significance.

So both of the pick-ups contained in the sensor read the lugs only??

I would say that the dimple is not big enough for any balancing purpose. But it could possibly be a timing mark.

now those indentations on back of flywheel are to locate magnets on inside of flywheel. |

Good stuff... thanks for clarifying that, appreciate the help.
