F.A.S.T Carb Sync Tool?

[foxracing350]

I just switched my twist throttle to a thumb and im pretty sure my carbs are out of sync now.

How exactly do you use this tool or is there any easier way to sync them?

ok and how do you use it?

Do you have stock carbs? and do you have the sync tool? To use the sync tool, (first take the filters or airbox of) tighten the throttle cable untill it starts idleing a little high then put the adapters on the sync tool put the tool up to the back of the carbs and look at the needle adjust the cables on top of the carbs until the needle is the same on both of them then let it idle and measure the air flow again with the sync tool and adjust the idle screw until the carbs are the same, then set the idle back up and double check it.

If you look at the of the carbs where the slide go in there should be a little window, your slide has a little hole or notch in it, it should line up with the window at WOT. hope that helps.

heres how i do it and im special lol sorry been drinking

 

 

pull air box off or filters off. take teh tool and put the adapter on it. and make sure you have some cable slack. get a base line reading at idle. then adjust the idle screws to where they get teh same readings.

 

do the idle first

 

then after you get the idle the same and at a decent rpm.

 

with stock carbs, try to get it where it revs up like 3-5k rpm by getting someone to hold the throttle or wedgeing a screwdriver up the housing. what ever you do try to to get a steady rpms

thats where the terry cable comes in nice.

 

then adjust them to where they pull the same reading.

 

and go for a ride if one pipe starts to ping before the other adjust the other side up just a bit. but if you get the reading damn close should be a problem.

Thats pretty much the exact method Ive always used and been told to use.. Works nice..

Good breakdown Wes.. :thumbsup:

The only thing i can add is that if you are installing a new throttle cable, recheck the synch after the first weekend or so of riding. In my experience they will change a bit when the cables are first new. I synch them when i put them on, after the first couple days of riding, and then whenever i am doing routing maintenance, i give it a quick check.

Nice post Wes....even for having a few Coronas....LOL.

That is exactly how I do it as well.

 

One last thing I would add is make sure you get WOT on the carbs. Bike turned off, hold the throttle wide open and reach into the back of the carb....it should have a clear path all the way through it with no interference from the slide....

vodka and lemonade was the drink of choice.

 

ill try to get a video of how to do the carb syncing lost shawns bike to do it on. will find another.

[foxracing350]

a vid would be awsome

thanks guys
