I'm not an expert but I just rebuilt mine and from the way I see it as long as you don't separate the carbs, mechanically the syncronization should remain the same. You can change the jets without separating them also. You of course won't be able to dip them or clean them to well because of the rubber parts.

Rebuild carbs.
Bench sync carbs.
Check and adjust valve clearances.
Vacuum sync carbs.
Guides and links to information, including jetting guides, are on my website.
Thank you for your indulgence,

The carbs need to be dipped to clean all the little passages between the jets. If you don't separate the rack, the o-rings in the fuel transfer tubes will be eaten away, requiring you to separate the rack, anyway.
Not sure why you are so hesitant to sync the carbs. That is part of the normal maintenance routine and will be done many more times than a good carb cleaning. If you do a PROPER carb cleaning that actually works, all you have to do is keep riding the bike, adding fresh gas along the way, to keep things clean. If you must store the bike for the winter, simply add some stabilizer to the gas before storing it. I cleaned the carbs on my wife's bike over four years ago and have not had them apart since then. I have checked carb sync every year, at the start of the season.

You should be able to visually sync them on the bench, but it won't be as accurate as doing the vac sync.
For what it's worth, I've bench synced the carbs on my Ninja a few times and never had to do any adjustments after I did that. However, I did the vac sync just to make sure.
I think it would be best just to vac sync them...but that's just me.

You can bench synch them but you might find it's wrong because one cylinder pulls harder than another or something.
You can't get a real synch without having them mounted & running on the bike you're going to use them on. They will be close though.

Bill rides an 1100 L as do I. Don't cut yourself short on performance, pull them apart, clean them, bench synk will only get you close. Do a proper sync. and hang on.

Also, a carb sync is one of the easiest things you can do to maintain your motorcycle. You don't even have to buy an expensive sync tool. There is a guide here to make your own for cheap.

reason im considering is before i acquired the bike it had a kerker megaphone 4 into 1 exhaust put on at idle it runs rough and if u bring rpms up between 2k-3k it will kind of pop through the exhaust other threads indicate the jets probably wasnt matched to the exhaust and if im having to jet it for the exhaust im going to go ahead and put pods on it any ideas on what size i should go to to get close and what jets need to be changed and which ones need be left alone thanks for all your input

Hi,
With pods and pipes, the most popular solution is the Dynojet Jet Kit.
Thank you for your indulgence,
