hello. I want to check my carbs sync since I experience some sort of vibrations in my GS (I know it's not unusual) but I want to make sure the carbs are synchronized.
I found that I could get the very cheap sync tool (Chimivee's sync tool or something like that) here on the forum... but I can't find who should I knock to...
can you give me some advice where can I get that or how to make that dsort of a tool?
PS I'm gonna do valve clearance check + chain adjustment on Saturday so I thought I could also check the carbs at the same time. So your help and quick responses are very appreciated!!!
thanks

Get about 20 feet of 1/4" clear plastic tubing. Loop the tubing into a big U and tape it to a yardstick. Get some water and add a little red food coloring. With the yardstick vertical, hold up one end of the tube and add water until the U is roughly half full. Shake any water droplets down into the U, then attach one end of the hose to the left carb and one end to the right carb. All set! Your finished tool will look somewhat like this (minus all the crap to the right of the U) (http://www.iflyez.com/ManometerGuage1.jpg)
Keep the U upright by hanging it from a tree or the ceiling. When both water columns are level with each other the carbs are in synch. Synch your carbs for about 6,000 RPM, which is about cruising RPM.
Rather than buy or build a fancy fuel bottle to run the bike with the tank off, get about 8 feet of fuel hose and attach it between the tank and the carbs. Set the petcock to "prime" and put the tank on a workbench near the bike. :thumb:
Here's the one (http://www.powerchutes.com/manometer.asp) I use, basically the same as Geep's. Although I used 2 cycle oil instead of water. I like the idea of just using a long fuel hose instead of buying one of those small fuel tanks just for this job, saves a little more money.
great!! thanks so much for you replies. That's all I needed!
I owe you guys a beer! :cheers:

BTW:
how were you guys able to take off the left carb vacuum cap from its port? it's pretty unaccessible (2001 model) :dunno_white:
I took the tank off to see what was it all like, but couldn't figure out how to do it without moving the carbs back a little. Seems odd to me that this might be the only way. Or maybe it is just me... :dunno_white:
Thanks :icon_mrgreen:
