FJ1100 Won't Run

[RPM - Robert]

Thanks everyone for the kind words regarding us.

We do also take PayPal so the credit card usage is moot. Pay with PayPal if you need to but clean and build your carbs correctly.

You should also get a service manual. That would probably help you out quite a bit.

Don't worry I ended up getting a Hanes Manual when i was trying to get the starter to work.

Back fire was through the exhaust we're pretty sure.

The "wasted spark" ignition system fires the plugs on the compression stroke and on the exhaust stroke.  Therefore, the backfire you heard was an unburned fuel mixture lighting off in the exhaust.

And if you didn't see any O-rings during your carb cleaning, then it was more of a waste of time than a cleaning.

Get the RPM kit.

One HUGE departure in this from the Yamaha version of these carbs is how the needle is held in place and how you adjust the needle!!!!  The FJ doesn't require snap ring pliers to remove the needles, and the spring goes ON TOP of the plastic "spacer" vice underneath.  Thinning that spacer on an FJ won't change the needle position.  On the FJ that is done with washers UNDER the clip. 

This is an awesome how-to on the disassembly and cleaning — BUT THE NEEDLES ON THE YAMAHAS ARE NOT LIKE THE ONES ON THIS SUZUKI EXAMPLE.  I'm sure our experienced folks won't have any issues, but want to make sure it doesn't trip up someone new to the insides of their FJ carbs

Thank you for pointing that out I forgot this was the page with that on it.... I have 2 other cv cleaning and tuning pages bookmarked I can post up if need be.  I did find them very useful and good to keep saved as to not forget anything...

Never noticed the "pilot jet plug" in my carbs, should there be one?
