If your carbs are very out of sync, then it doesn't really matter how fast you are turning it because all the liquid will shoot over to one bottle right when you turn your engine on. Then it will only be air being pushed in to the full bottle from the empty one, causing the bubbles. If you turn the screw the right way, the bubbles should essentially stop on one side while the oil is starting to move back over. Then just gradually slow down until everything has stopped. I would suggest, if you can still remember which way to turn the screw to move the liquid back into the other bottle (empty one), give it some turns before you turn your bike on to get them back into better alignment so you don't have complete drainage of one bottle. Personally I eyeballed the butterfly valves when I took my carbs out, and when I did get around to syncing them the first time, there was very little flow and I didn't even think it was working :P If you are really worried about it happening again, I would eyeball it (super easy if you have no more airbox!) |

I feel kind've dumb asking but when you say "eye ball" do you mean look at the butterflys and see when they are close to being all the way closed? First time doing this so Im kind've green.

Yeah, you can move them with the actual throttle on the bars/throttle on the carb, and then adjust the screw so that they *Look* like they are closing and opening at exactly the same speed. You will know what I mean when you try it. |

Yay old thread revival!
Would this DIY sync tool also work for a throttle body sync? |

I wanted to do a DIY carb sync but didn't have any bottles/containers laying around that I thought would be good for this. So instead I bought 2 cheap vacuum gauges off ebay, attached a hose to each, attached each one to one side of the carb and presto, Carb sync tool for $15, 5 for each gauge, 5 for a big roll of tubing.
Only thing is the tube is to big and needles doesn't stabilize so you need to choke the tube a bit with pliers, vise grips work well, I had hemostats that worked as well and the needle will stabilize quite nicely. So another option that isn't quite as expensive as a $40-$50 sync tool
