Help Sync the carbs
Hey guys, Im trying to sync my carbs on my 99 f4. i have the sync gauges and when i hook them up to the vacuum ports attached to the air box my gauges start going crazy, has anyone had this problem or am i doing something wrong. I followed the service manual and i am sure i have the gauges hooked up right. I also hooked a vacuum gauge up from my mighty vac kit and that gauge does the same thing. It does not change when i rev the engine up either they still go whipping back and forth. Any help greatly appreciated
Thanks, Josh

the gauges are deffinetly for doing carb syncs. The bracket which holds the gauges says carburetor synchronizer on the top and the gauges read vacuum and also show late timing and stuff like that on the pressure side of the gauges. I have not done a valve adjustment yet the clock is only 15,000 miles do you think that is the problem? the idle is also right on.

Disclaimer - I just joined the group and don't own an F4/F4i just yet, but I had the same problem on my SV650 with gauge type synch. You may need restrictors in the lines leading to your gauges. Too much vacuum can make them really jump around. I have the motion pro carb synch and it comes with restrictors for the same reason. You can pick them up and most autoparts stores.
