Syncing the Throttle bodies

Has anyone done this themselves yet? i just installed a K&N filter and even took the fuel tank off looked around and saw the four adjustment screws but didnt see where the hoses would connect to a meter.

Also was thinking about a JB-pro and it looked like it would be really hard to get to the connectors to install that. any tips?

On my Fz1, which shares the same engine as your 8, it was fairly easy.

I ordered a Morgan Carbtune which took about 2 weeks to get to me. That was easier albeit more expensive than making a manometer.

You unhook the blocked off vacuum hoses and make sure attach them securely to the manometer. The trickiest part was having to repeatedly let the bike cool down between adjustments to keep the temp around 170 degrees.

Done on an Fz6 but smiliar concept, and you should be able to extrapolate from the service manual the differences.

I found my bike ran a lot smoother after I did it.

hey ssky, do you have to adjust the morgan carbtune before each use like you have to with the motion pro one?

I did mine. It's a fairly easy task, chapter 3 page 9 of the service manual covers it pretty well. The hardest part was finding and disconnecting the vacuum hoses for TB's 1 & 3, it was buried and very hard to reach. I rerouted the hoses after I finished so they'll be easier to get ahold of next time. Throttle body sync hoses 1 & 3 connect to a common hose joint and 2 & 4 connect to a common joint.

No problem cambo. I had borrowed the gauges earlier in the week and was planning on doing it today anyhow, so when I saw this thread pop up last night I figured I'd take some pic's. It was easy to do and the bike is running smoother. Let me know if you have any questions when you do yours.

Sweet, cambo bought a gauge. Can i borrow it when you're done? Or we could all meet up with Rabbitman for some beer and sync the throttle bodies

Sounds like a synchronizing party :-D

Oh yeah! Beer, babes and throttle bodies! Sounds like a a hell of a party! cambo brings the sync tool, thatch brings the beer (real beer please, no fruity lime flavored stuff) and Rabbitman and tjfisher bring the girls. I've already sank or sync'd my throttle bodies so I will gladly accept the responsibility of monitoring the ladies and the bier :D

For the record, Amanda, if you somehow see this, which I know you will, somehow...I will not look at any of the babes. I will only partake in beer and stare only at the babeom...I mean Manometer.
