Leeroy Posted June 30, 2008 Share Posted June 30, 2008 It's just not fair! What is it with New Zealand and GSRs? Seriously, there is a tool called a carb balancer (or carb syncronizer) which is a vacuum gauge that allows you to tune both carbs. I don't think they are very expensive either.

I think this tool is commonly used by motorcycle mechanics if that helps at all. Quote Link to comment Share on other sites More sharing options...

Reveeen Posted July 7, 2008 Share Posted July 7, 2008 The trade name is "Uni-Sync", the money should be $20, it is suitable for 2 carbs only, 4 would be a handful. Or, use a piece of heater hose inserted into your ear, listening carefully to the draw through each carb, make the noise you hear the same from each. Whatever method you choose to use, there is a learning curve involved, don't expect miracles the first time. Quote Link to comment Share on other sites More sharing options...
kiwi subbie Posted July 8, 2008 Author Share Posted July 8, 2008 is it ok to use an motorcycle carb syncronizer to do car carbs? or would the car carbs be to big and cause to much vacumme or something to get reading? Quote Link to comment Share on other sites More sharing options...
naru Posted July 8, 2008 Share Posted July 8, 2008 is it ok to use an motorcycle carb syncronizer to do car carbs? or would the car carbs be to big and cause to much vacumme or something to get reading? Should be fine.Unisyn and others are adjustible for different airflow rates and are intended to check synchronization at different RPMs anyhow. Pretty simple,really.Used to use one regularly on a 4 carb car. There are some pretty big bike engines. Quote Link to comment Share on other sites More sharing options...
