FUBAR!–My Caponord is dead…..

September 13, 2012

Sponsored by:


I noticed recently that the Caponord was getting worse and worse fuel mileage.  From low 40’s to a solid 35 MPG or less.  Going 200 miles on a tank was impossible.  Then this morning the EFI warning light went on and stayed on.


I pulled the diagnostic codes from the bike and the code indicated a rear cylinder coil failure.  So, under the fuel tank I go. 

What do we have under here?


FUU#()@#)!~!~!@#@~!)(@#)#!!! A freaking mouse condo!  I’ve most likely ridden close to 12,000 miles with that crap in there!  No wonder the bike accelerates poorly.


Let the cleanup begin


So, I clean the velocity stacks and butterflies with carb cleaner and replace the faulty coil.  I button the bike back up and it won’t start.  I think it’s flooded with carb cleaner and let it sit for a while.  Eventually I get it running but very poorly and the EFI light is still flashing..GRRRRRR. 

During this time I’ve been hitting the starter button a bunch to try and keep the bike running.  Stressing anything electrical on an Italian motorcycle is never a good idea.  I decide to give up and turn the key off and hit the kill switch and begin to walk away – when the starter engages and begins to crank the bike.  NO key in the ignition, the starter button in the OFF position.

HOLY SHIT!  I know something is going to get fried if I can’t get the battery disconnected quickly.  I fumble for a wrench while the starter spins and spins.  I consider cutting the battery terminal lead.  I end up getting the negative terminal off just as the battery starts to die.

So now, I have a bike that won’t start, most likely has a fused starter relay, and may still have issues with the coil.  Fan-FREAKING-tastic afternoon.

But, there are parts available, I know I’ll be able to fix it and no matter what, It will ultimately be better than when I started.  So I can live with a dead motorcycle for now.

That’s my day – how’s yours?

      Starter relay – schmacked it with a hammer and problem solved. There is an upgrade available from a Yamaha part at less than half the AF1 price. Ordering the part from Amazon and adding new plugs, filters, and seals.

      Should be back on the road soon.

    Bummer. I know that feeling. I sort of felt the same way when I learned that Dustin Diamond turned down the role of Abraham Lincoln for an upcoming three-part miniseries on the Civil War. (Steven Segal ended up with the part…)

    I think I’ll put fresh bait in the traps in my garage.

      A few years ago I had motorcycles and expensive cars stored in my 3 car garage. As a hedge against critters I littered the place with rat kill pellets. After a few weeks – they were almost all gone. Eureka! Problem solved – I thought. That spring I was getting my Carrera 4 out and checked the front compartment. Underneath the space saver spare – mounds and mounds of rat kill pellets with about 3 dead and very stinky mice. Rodents seem to have quantum mechanics figured as I can see NO way they could get into the Caponord airbox….. I’m afraid to look under the tank of my Futura………….. My next garage will have those electronic pest devices.
