How to Sync Throttle Bodies on the FZ6R - Page 3 - Yamaha FZ6R Forums - International FZ6R / XJ6 Motorcycle Community Forum

jester8p · 06-29-2010, 08:49 AM

So after getting my Carbtune in the mail I decided to sync the throttle bodies...holy cow what a difference. #2 and #3 were out of sync and after syncing it all not only did my idle smooth out much better, but the annoying 7K buzz that the fz6r are supposidly plagued with is all but gone.

I highly suggest that if anyone gets the annoying engine buzz around the 7K mark to sync the throttle bodies.

Yep, my Morgan Carbtune Pro came in the mail last week. I'm just waiting for some decent weather and free-time to be able to sync the throttle bodies and adjust the idle.

Is this an installation kit? What mileage is it recommended for it? I know newer bikes do run better early than over time and later need adjusting.

Robert.. I'll help you break i..I mean work on it.. I'll be free afternoons this week..

No, it's not a kit. The Carbtune is a vacuum manometer. http://www.carbtune.com/

I should be free in the evenings after work, as long as it's not raining (still need to clean up the garage so I can have my work space back). I'll let you know.

Do that, I'll be around.

I bought the cheapest mercury 4 tube gauge I could find.
My #1 cylinder was below 24 so I adjusted it so the high pulse was just below the mark and then adjusted the other 3 cylinders to the same mark.
The furthest cylinder on the right was way high and #2 from the left was low.
Afterwards the engine runs smoother than when I bought the bike.
I did accelleration tests on freeway onramps and it definitely has more power than before.
It takes about 10 minutes to raise the tank and hook up the vacumn gauge and do the adjustment and put it all back to the way it was before. Very easy and well worth the cost.

I looked for vacumn gauges on gauges on eBay and they still have the one I got. The ones with the analog gauges are a pain as you have to calibrate the gauges before use and then they are not that accurate unless you buy the high $$ ones.
