I'm wanting to run seafoam through my F3 but as I'm brand new to bikes can someone point out where the vaccum line is that runs to all the carbs?

I've used seafoam for years in my cars and I get the best results from using the vaccum line over just putting it in the gas or crank case which is why I need the vaccum line.

If you have pictures that would be best.

Thanks!

 

No one has done this? Sad

 

Does such a line exist? All the lines just lead to the airbox which would be the same as you just pouring seafoam on top of your carbs... You could just get a funnel connected to your main gas line and use that? might mix it with some gas though

 

In a car, you have a common intake path through a throttle body or something similar that you could attach to a vacuum line. 4 separate carburetors, 4 separate intake manifolds, 4 separate vacuum lines. You'd need to connect to the same port where you attach the synchronizer to. Do each one separately.

Probably easier to just add it to the fuel like the can says.

 

I know I can just pour it into the fuel tank and into the crank case and it'll help but the impact is so much greater when you have it go straight into the intake via a vacuum or brake booster hose.

I guess I'm out of luck and will just use it via the gas and crank case.

Thanks

 

I got a 4 into 1 manifold for a fish tank to make a carb sync tool from a pet store for like $7. I've never used seafoam but you could probably use the same ports you use for syncing carbs. Just have to get an extra one for the #1 cylinder which I got for $3 at a honda dealer.
