Throttle body sync

I got my bike ( 2000 M900Sie ) on the road finally. Seems to run a bit uneven a slower speeds and launch- even after fully warm- 45 minute ride. I have been searching for how to check the throttle body sync. What tool would I need? I have a Weber carb sync tool. Or Any help would be appreciated.

Re: Throttle body sync

A plastic tube with some 20w 50 oil. Attach it to a piece of particle board and start syncing..Oh and you need a screwdriver, flathead. Read up on how to do this right our you will FU_K up your idle guaranteed. Once you do it once its a piece of cake the next time.

Re: Throttle body sync

Ok..maybe thats a bit too vague..here's some links to explain further.. The 1st link below explains how a manometer works. read through it. Figure 2-1, 2-2 and 2-3 are what i'm talking about. Each end of the manometer ties into one one respective side of your throttle bodies. If your throttle bodies are out of sync one side will move up with respect to the other side. This means that one side is pulling more vacuum than the other. There is an adjuster screw you can reach to sync the throttle bodies. It can be seen easily if you are looking behind the oil cooler with your head on the ground looking up.

Before you do any of this work you have to close the open idle bleeder screws located on each throttle body.

Second link shows you what a cheap manometer looks like: You can see the two ends that connect to each respective throttle body.

If all this sounds confusing, take some time to throughly do some research before you jump into this.. its easy to do if you are well informed... I'll post some DML threads on it for you later.

Remember whatever fluid you use DONT LET IT GET SO HIGH THAT IT GETS SUCKED IN TO THE ENGINE. THAT WOULD BE CATASTROPIC

Re: Throttle body sync

I dont know if you've disconnected your charcoal canister but if you havent, then follow the hoses and you will see that the canister connects to both throttle bodies. This is where you make your connections with the manometer.

While it's not exactly a good idea to suck whatever fluid you're using into the engine, it's not catastrophic. The amount of oil you'd be using is just going to make the engine smoke a bit til it burns off...

Re: Throttle body sync

I have some 5w oil that should be good for this. Otherwise I will use ATF.

Thanks again for the info and diagram, looks to be pretty straightforward.

Re: Throttle body sync

ATF is good for cleaning the intake anyway!
