mc16 tach needle barely moves

jcl777 » Wed Aug 31, 2016 11:56 pm

Hi all.

I've got a 1987 MC16. After not riding for a few months, I fired it up to find that the tachometer was misbehaving.

As I rev the engine in neutral or in gear, the needle blips up slightly but much below 500-1000 rpm.

Any ideas what could cause this? I believe the tach is driven not mechanically but by an electric signal. So contacts rusty, kink in cable, what? Bike has been stored inside a dry area, so I'm not sure why this happened.

Any other diagnostic ideas would be appreciated. I'm able to use a multimeter but not really sure what to look for.

Thanks in advance.
Josh
