1981 CB900F
« on: March 25, 2009, 07:27:57 AM »
All is not well with this.  As posted earlier, I have rebuilt this monster for a friend.  Head is polished, intake side pocket ported and matched.  Carbs are rebuilt..68 primary, 115 secondary, and 35 pilots.  Electronics are good....bike runs well......maybe.  The clutch lever has a switch in it...changed it 3 times to be sure....but when you let out the clutch lever.....the bike dies instantly, even in neutral.  Is this a bad nuetral safety switch?  Already checked the little diode and found it bad and replaced it.  Bike still does it.  If I unhook the switch at the lever and put in a jumper...the bike runs.  so I am assuming (assumption...the mother of all --ck ups) that the neutral safety switch is bad.  Any other ideas.

Some bikes of the era also had a switch in the sidestand.  Dont know if this did.  There is a dohc4 site also.
