is there a single set screw for the air to fuel ratio or is it controlled through each individual carb??? my bike is running extremely rich across all 4 cyclinders and i am not sure why but this is the best thing i can think of doing at the moment... thanks...

 

The only way to change air/fuel ratio is to change the main jets or needle possition in the carbs. If your bike was running ok before and no changes were made resently i'd sugest chanhging the air filter or fitting an aftermarket one like K&N and see how it goes then.

 

is there a post about needle positioning that someone may have the link to so i can take a look and see what i did that caused this problem... what i did was i took all carbs apart and cleaned them out with sea-foam... so that is where im guessing i would have made the mistake... so if someone can tell me how to check it or link me the post that would be great... thanks...
