Hi everyone!

[JuanZi]

I am a longtime Yamaha rider,with a just purchased 85 fj 1100. It seems to be mechanically ok in spite of some very dubious stuff,like a missing synchro vacuum port plug. "I dont know why it idles at 4000" LOL. Right now,my priorities with this bike are a new windshield,confirm synch before plugging port,and changing neglected oil.
Cheers!

 Welcome to the forum. FJ1100's are my favorite .
I bought my last windscreen from Zero Gravity .
The left two intake vacuum ports should be connected to the ignition module for an antismog function and the fuel petcock for fuel shutoff.
   The petcock has a prime position that allows fuel to flow with no vacuum present . You can use that position to run the bike while your vacuum gauges or manometer are connected to the vacuum ports for carb balancing.

Welcome Juan! I glad that poor bike is in your hands now.

Cheers

Welcome Juan,

Very hair to see another FJ being given the love it deserves 

They're superb bikes once properly set up and maintained.
