1100 Carb sync. Please read

[MindWebs]

If you want a "GOOD" carb synconization, you must FIRST calibrate your Vacuum gauges!!

(Moderators note - the following link will generate a pop-up ad that may be offensive to some)

Here is the procedure: http://www.megaupload.com/?d=WC0A3044

The download is free, the process is free and requires no parts or money.
this will help you properly calibrate your gauges to top performance.

If an Admin would please install this to the tech page!! Please.

I did the calibration and then sync'd the carbs, Now my XS11 special will almost throw me right off the back of the bike.

Good luck and happy tuning!!!

well... thats what happens when you let your wife drive!

I calibrated my gauges by attaching them, one-at-a-time, to my vacuum brake bleeder. I pumped the bleeder up to 20 cm of vacuum on the bleeder's gauge and checked the reading on each synch gauge. I put little pieces of tape on each gauge so I would remember to take the appropriate 'kentucky windage' when doing the synch. I recently purchased a carbtune pro, and found that I had my gauge set dead on using the above procedure. If you don't have a power bleeder, you can achieve very good results by attaching them to the same carb tap, at the same rpm, and taking a reading. I looked at the above link, but I'm hesitant to download executable files unless I really know the website I'm downloading from.

I have sticks.
They're always calibrated!

JC Whitney Gauges

I bought a set of vac gauges from JC Whitney to do my carb sync. They are similar to the ones used/calibrated in the "download" mentioned. (Mechanical diaphragm and a pointer/needle...).

Before I actually used them on the bike, I "tee-d" them all together so the four gauges would read the single vacuum connection. None of them read the same amount so I took the gauge covers off and adjusted each one to read the same number.

Didn't use a calibrated vacuum source so now there may be an error in the actual vacuum present and what the gauges read. But then again all of the gauges read and would read the same amount of vacuum whichever carb they were hooked up to. Still good enough for determining which carbs are higher/lower than the others.



And YES....even though the bike would start/run, the "sync" did wonders for performance and peace of mind.

I started with a set of mercury sticks. They were great until I got a backfire through the carbs while doing a synch. It shot fuel down the line and contaminated the mercury destroying it's usability. That's one thing I like about the carbtune - it uses steel rods instead of mercury, and if you get fuel in the chambers it can be taken apart and cleaned. Works just like mercury sticks but without the problems associated with mercury.
