I would like to share my experience with the "Bebe" method. I made two loops of tube.. one completely closed off with a bebe inside (the 'gravity' bebe) and another loop just outside of that one. I used two vacuum restrictors on either side of that tube, and connected those tubes to the carb sync ports. I started the bike and warmed it up, got it to idle around 1000, and hooked it up. The vacuum bebe was dancing back and forth about a distance of 1/2", so I did my best to center the motion with the gravity bebe. Seemed to work okay and balanced 1 to 2, 3 to 4, and finally 2 to 4. Took it out for a spin. I think it definitely rides better, could just be my imagination though. Feels very smooth in 2nd gear at 3500RPMS or so. Got home and just for fun, hooked up my home made liquid sync. Way off. It rides better so I am not as concerned with it anymore. Should I try again with the bebes? Should I have sync'ed 2 to 3 at the end instead? I know the manual says 2 to 3 but i forgot and I didnt have the manual with me :/ I may try again using a larger loop for the tubing. My current one has a small, maybe 4.5" or 5" diameter. I wonder if its too tight for the bebe. The bebe doesnt seem to be bothered by it, but the ones I've seen here seem to do the trick. Does having 2 or 3 wraps on the vacuum coil make a difference??

I have a 1st generation.. correct me if I am wrong but isnt that link for the 2nd? I have the service manual at home and it appears correct. Thank you

Don't mean to hijack the thread, but I really like the bebe idea. No risk of sucking anything into your engine, which I like. I bought a 300 pack of bebe's for $1.50. If anyone needs 298 bebes let me know : ) I will, hopefully, repost on my success later.

Actually, after yesterday, I'm fairly convinced that my home made sync won't work, at least at this stage of the gane.. I think they are so far out of wack it's becoming very difficult to sync them properly. I need to sync them with the right tool first, then I think my home made sync will be easier to use for future syncs.

I, too, have made a homemade Carb Sync.. Even with the vacuum restrictors, the fluid (transmission fluid..) still flows pretty freely.. Would having a larger "tank" for the fluid help with that? In other words, where the fluid sits at the bottom, should that hold more fluid than just what the 3/16" tubing can hold? I try to sync the carbs a little bit without starting the bike and just blipping the starter.. but i still have a hard time with it.

Thanks for the help everyone.. I am going to run some Seafoam through it over the next few tanks of gas. 1 Can to 1 tank to start, adjusting as necessary (though if that doesn't clean it out after a few tanks, then, well, screw it )

Thank you! I just put another 2 gallons or so in the tank. I will add a can of Seafoam, then fill it up, ride it around, repeat maybe once or twice.. then change the plugs and get 'er synced : ) Thanks for the advice! Any advice that contains "ride around" is the best. Now to get it insured and registered..

First I would like to say that I have been reading the forums a bit, trying to figure out my problem.. See, my bike (83 XVZ12) was sitting in the shed for almost 2 years. I figured it would be a good time to clean the carbs (something I am not comfortable doing myself.) The man at the shop was very kind and insisted I try to Seafoam it first. So I added almost 16 oz to about 1.5 gallons of gas, ran it for a bit on idle (to clean out the idle circuit) and let it sit for about 2 days, then ran it again. Ran through the entire Seafoam/Gas mixture, added regular gas to the tank, and to me, it runs a little better. One problem It has is that it idle's funny. I start the bike cold with the choke on until it's idleing at 3000 or so RPM, then slide the choke off. If I slide the choke all the way off, it will stall every time. Not sure if that is a feature or a bug, but I adjust the choke to get it to about 1000 RPM idleing. It idle's reasonably smoothly now. Until I try to give it throttle.. When I give it slight throttle, the first thing it wants to do is stall. Often times it does. Giving it very little throttle will drop the RPM to about 5 or 600 before it kicks up.. 1000-2000RPM is sloppy, after that it sounds like a mean machine and the gas seems to work pretty good. I think it's a carb sync issue.. what do you all think? I spent the morning trying to make one of those "home made DIY carb sync" tools with 3/16"ID tubing and connectors, and when I hooked it up, the fluid rushed towards the carbs almost too fast for me to shut the bike off in time. Do you think I just need to get the carbs sync'd? Thanks, Steve
