Fz misfiring...
« on: 29 June 2015, 08:13:38 am »
Morning.
So the bike has been fine for the short time i have owned it and nearly 1k miles i have done so far...
Last used it Saturday with no problems, got it out of garage an hour or so ago, started fine, ticked over fine for few mins then after 500 yards or so of very slow riding it started to misfire.. Bliped the throttle a few times but it would not clear  :\

So its back in my garage and i had to use the car on this beautiful day  :'(
Will have a look tonight when i get home, will start with leads and plugs... Is there a common problem i should check for??
Thanks.

Check every eletrical connection you can get at,  pull them apart and check for corrosion.
Fuel filter and air filter ok?
I assume there is petrol in tank :)

Did a quick google, our US buddies have this a fair bit and mostly falls down to coils.
I will have a look later when i get home but yes will check all connections and there is over 1/2 tank fuel
Thought the HT leads plugged directly into the caps, not sure if you can cut these down?

Fairly easy to be honest, drop rad from mounts, pull down and access from top

At least you know the cause of the misfire now, how many miles have they done?
