Check out this link for a mana-mana do do do do do! (I WILL be singing that all day now!) carbtune.com/index Last October, I was trying to get my sportbike ready to do my first track day and needed to get my carbs sync'd. I did NOT want to mess with mercury, and have heard quality problems with those vacuum gauges you can get from JC whitney and apparently on Ebay. I used this tool, and got my sportbike running very smoothly. I will tell you that everything on the tool is 'good' quality exept how they have the 'loop' hooked up to hang it from the handle bar when you are adjusting the carbs. I made a very quick inexpensive version out a couple of zip ties and some wire. I looked all over the net to find a tool, I found some home made plans that looked like they would work, but this one looked the best, a little expensive, but I am going to use it over and over on several different bikes so I fiqured what the heck..
When sync'ing the carbs ( on a lot a bikes) you need an aux fuel tank because you need to remove the fuel tank (not sure on my vulcan because I just got it last week, probably can leave the tank on). Again, instead of paying 50 bucks from Dennis kirk or other suppliers for one, I made one from a funnel with a twist valve on the bottom, some vinyl (clear) tubing and fuel line and some hose clamps. I found the vinyl tubing helps to see the fuel on it's way to the carbs. Looks like on the vulcan you may also need a fuel line "T" fitting because of the dual carb/fuel line set up (I found a plastic automotive vacuum line fitting with universal size barbed connections for like 2 bucks) and boom your in business.
By the way, this is my first post here. Like I said just became the owner of a 2003 Vulcan 750, and am probably going to have to take the carbs off in the very near future (monday when I get my book from Kawi) to fix a rough running idle circuit. The bike sat for almost a year with no running, before my buddy decided to give me the bike. yes I said GIVE me the bike. 2800 miles, not a scratch, just does not want to idle or have any throttle respone except coughing and spitting at me. Never had anyone do anything like that for me. Pretty cool. I am still blown away and head is still reeling..He was having health problems and said it was a shame to just be sitting in the garage. sooo....
glad I found this site, already have found some good stuff!!
ps, for those of you with more than one bike in the garage, this manometer works on 2 and 4 carb set ups. pretty cool. and no I don't work for or represent those guys, they are based in the UK.
