Getting some posts up. A carb sync is easy you can buy the card stick for less than the shop labor coasts to do your first carb sync. For inline 4s remove tank add a extended fuel line with a hard piece of pipe to join the 2 lines together, clamp them together, put the tank on prime ( PRI ) set the tank slighty higher than the bike be careful not to let it fall. Next remove vacum caps on each intake tube some models on carb. It is a good idea to get 4 extra caps from a autoparts store usualy 5/32 in size they usualy split comeing off. Slip the hoses on each vac port 1 to1, 2 to2,and so on. Put a fan in front of the bike for cooling, start it and alow the bike to come to oprating temp. there is three adjusting screws 1 center and one on each side between the carbs. Start by making the out side carbs the same on the mercury scale then the center carbs. DO NOT REV ENGINE WHEN YOU LET THE THROTLE GO, TO FAST A SUDDEN VACUM CAN PULL THE MERCURY INTO THE ENGINE. You want the 4 tubes of mercury to be the same as close as posible an 1/8 of a inch isnt a problem but no more than a half inch 1/4 prefered as max. On a 2 cylinder the process is the same except only one adjusting screw between the carbs the extra 2 hoses on the stick are not used. This usualy takes longer to remove the tank and prep for this than the actual adjustment. I can do my ZRX 1200 in 20 minutes. The stick coast me 45 dollars and shop would charge 65. It is recomended to sync anytime you remove the carbs for service,jeting,or overhaul. If anyone has a ? or more detaled info just reply here. This is also done on fuel injected models.

 

good write up but..

well I wouldn't say worthless but it would be better

 

Dont have pics, but a service manual will show a few and give great detail.

 

Awesome! We're going to need posts like that to help people like me out! Keep 'em coming!

 

Thanks bluebird.

 

Bumping the oldest thread in every section.....I know its sad, but just wanted to see what happened...LOL

 

does anyone have video of a carb sync for 2003 ex500 Ninja?

 

I have not searched for one. Your manual explains it well I think. only using two gauges of your tool, the manual tells you the readouts and where to adjust. No brainer.
