Removing Starter Motor Safety Unit
« on: November 08, 2010, 10:56:54 AM »
I'm doing a 73 cb750 cafe and don't need or want some of the features like the clutch switch, neutral switch, etc. that are covered by the starter motor safety unit. I could track these individual bits down but thought removing the smsu might be simpler.

I found this thread, which seems to suggest it is relatively straightforward:

but then the discussion gets into some confusion about which of the actual wires from/to the smsu need to be jumped.

I still want electric start so I'm wondering if someone could just confirm the feasibility of removing the smsu.

Thanks in advance.
This project started in confusion and will end in disarray.

I'd quote you the page number if I had one of my books handy, but...  ;D

Find the Dark-Green/Red wire that went into the red connector that plugged into the safety module, pull it out of that connector and change the end to a male bullet, and plug it into the extra Green wire that is hanging near the rear of the battery box. Presto, it becomes a K0-K2! Just don't forget to pull in the clutch or find neutral before starting, or you'll make the DOT mad...  >:(
