How to Sync Throttle Bodies on the FZ6R

[jester8p]

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.

YES.......

pure freaking mercury and it's heavy too..surprisingly so.

Well, at $50 shipped, I ordered one....
sounds like a good investment for any motorcycle owner!

P.S. there should now be 4 left from that link.

I did not see any photos on the first and second entries?

I see them ,but was just thinking, we need this write-up in pdf, just so who ever has the pics on their photo bucket account don't get lost.... I can try it, but my pdf outputs are limited.... anyone else?

I could give it a shot too.

Ok, here is the link to a PDF version of the How-to. I didn't do any editing; I simply copy and pasted the entire text and inserted the pictures.

PDF is fairly simple. I wouldn't mind helping do that. I'm not sure if we can host anything other than pics here but I do have my own web space that's not really being used so I can link to it.

Could also do a web version as well so we have some backup.

Awesome! My stupid word to pdf converter only does one page at a time.... too lazy to go buy a real one.

Wonder if we could set up a pdf gallery on this site? Many people have spent their time to do this for the rest of us, it would suck to see them leave the site, or clear out their photos only to lose such great write-ups!

I was just going to copy/paste into Word 2007/2010 format it and then just save as PDF...

You know, I have been thinking about that for quite sometime now. I was actually going to take all the how-to's and put them into PDFs and then host them all in one place. I just need to get the time to do it.

So, here's my before and after... the guide was spot on! Piece of cake, no issues!:cheer::cheer::cheer:

your picture showing adjusting idle is wrong procedure. you should never use
this area to adjust your idle. there is a special screw for adjusting idle as shown in service manual. manual states never using the lock nut allen head.
to adjust idle.

It appears butcher birds post has gone somewhat unnoticed or ignored for some reason. He's right that the manual says to adjust the idle using a different screw instead of that locking nut assembly. That should get corrected, no?

Yes, if the OP wanted to fix that sure... I think the reason it's been ignored, at least for me, is that right now my idle is not at issue, and probably won't be for a long time.... I think that called out adjustment in the guide is meant to be more of a "limit" adjustment... it will adjust idle, but "shouldn't be used", the right screw looks to be the screw right under where you adjust the throttle bodies.

Oh,,, and one more "TIP"... I simply looped a piece of wire through the top of the manometer (it has a hole in the metal plate), then hooked that over the handlebar and over the switch assembly to make sure I didn't spill mercury. I would not recommend just propping the manometer against the bike.
