MT07 Throttle Body Synchronizing | All Years 

Awesome! I’m glad I could help

@@BradTheBuilderChannel bonjour Excellente vidéo, très explicite, Le voyant moteur s allumé car je pense que la vis de gauche est la référence de l injecteur, donc en utilisant celle de droite ecu ne le prendra pas en considération. C est juste de la théorie,

@@christiandelannoy9991 bonjour, vous devez utiliser les deux prises pour équilibrer les corps de papillon, donc peu importe ce que vous devez retirer cette ligne de vide pour ce faire. Le voyant de vérification du moteur est normal pour cette procédure et n'est pas préoccupant. merci pour le commentaire et j'apprécie les belles paroles.

@@BradTheBuilderChannel Merci pour la réponse, donc pour le reglage parfait il faut ce concentrer sur le ralenti pour connaître la bonne valeur.

@@christiandelannoy9991 Les aiguilles de la jauge seront légèrement décalées lorsque les corps de papillon sont déséquilibrés. La vis sur l'une ou l'autre des prises en fonction de celle qui est désactivée corrigera l'aiguille afin que les deux soient alignées. Vous ajustez la quantité d'air entrant dans le moteur pour créer une compression équilibrée entre les deux cylindres. Il n'est pas directement lié au ralenti bien qu'il soit affecté par la dépression.

No plans to do any front end mods yet but that’s not to say it won’t happen in the future. Let me know how it goes

There is a proper vacuum pressure but it’s not near as important as each cylinder matching each other. When vacuum drops so does the idle. You can hear the difference. I can swing back with the proper pressure and let you know what it is. If you continue to adjust down the pressure will be too low for it to run properly. If there is no vacuum your engine isn’t running. Here is another good video on the throttle body sync and he is a certified motorcycle mechanic. He also states that the reading doesn’t matter as much as it being synced. It’s a good video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ARTuvn7Vf-s.html . Hope this helps! Peace

Change it first than do syncing to be safe.

No there is no set baseline but people often balance with a single hose with fluid connecting the two throttle bodies. The idle of the bike is directly affected by the level of sync. It’s a matter of seeing which is up and down and adjust one up and one down to become level. You need to use your ears and you will clearly hear the difference how well the two cylinders are firing. I used the right cylinder to balance the gauges but you could use either. Both cylinders use the same compression ratio and need to be the same. Internal wear of the throttle body butterfly and valve sealing issues will eventually cause your throttle bodies to become unsynced again this is why it’s good to check I would say every 5000 miles or so or when changing major parts related to the engine. If you adjust the vacuum too low you cut off the air and the bike will shut down. Too high will cause a high idle. When syncing them the adjustment of the screw will be very very minimal.

Also is there a screw on each side or only on the right side?

So you connect one of the cylinders doesn’t matter which one to a t connector that splits into two gauges. You use this to sync the gauges. Then you hook each to its own cylinder. There is a screw on each side that can be adjusted.

It is a difficult process and takes patience. The space your working in is tight. Use the small flat head screw driver to help you remove the hoses on either side of the throttle body. There is enough room to get to the screws through the top but it has to be in the exact right spot. I wish I could help out but don’t let the struggle stop you.

@@BradTheBuilderChannel ok, thanks!

It wouldn't be a bad idea to do a throttle body sync. I have a feeling something may be out of wack with the pcv though. Go in and make some fueling adjustments at those higher RPMs and see if it makes a difference. If you don't know how, I would reach out to dyno-jet and have them guide you through the process. If it continues, take off the pcv and see if the problem persist so you can narrow down to the root cause of the issue.

@B-rad The Builder that is my plan. I did make a few adjustments and the issue happened later in the rpm range after adjustments. My only concern is I've been running the same tune for several thousand miles and it acts up now

@@kylerothermel9497 have you tried reaching out to dyno jet yet? I would give them a ring if you haven’t yet

@@BradTheBuilderChannel I did, same thing we already know. I have a few things I'm going to test before pulling the pc5 out.

@@kylerothermel9497 comment back if you figure it out. I’d be interested to see what it was

First step is syncing the gauges to 1 single cylinder on the bike. This allows you to make sure the gauges are calibrated. This setup procedure is extremely important. Then you hook each gauge to the cylinders on the bike individually. Then you turn the screws on the throttle body to balance the gauges for each cylinder.

Looked like the backing plate of the gauge moved...not quite synced if that happens yeah?
