I'm planning on cleaning my throttle body/combustion chambers with some Seafoam. I thought I would just pour some through the throttle body until the bike stalls, then let it sit and start it up again, but the instructions on the bottle says to pour it through the vacuum line.

Not sure where the vacuum lines are- I suppose it's in the Service Manual, but if anyone has used Seafoam for this, which method did you use?

You don't have an open accessible vacuum line.  You can mix it with the fuel though.  Just don't dump the can like it's instructions might suggest.  Much smaller gas tank so figure your ratios.

I've already put some in the tank as stabilizer, and plan on putting some in the tank every couple months, but I thought I'd do a more concentrated cleaning of the chambers by putting it directly through the intake. Seem to remember doing it on cars years ago with other fuel system cleaners, so I thought I could do the same here, unless it's not safe/recommended to do so.

Actually, this is from their website but is referring to cars and mentions putting it through the manifold vacuum line:


To clean carbon and varnish deposits from the tops of cylinders and the backs of intake valves, add 1 oz. Sea Foam to each gallon of fuel. Sea Foam will slowly re-liquefy the varnish and gum deposits that hold carbon together.

To remove carbon and varnish deposits more quickly, Sea Foam can be induced directly into the combustion chamber via the following method. With the engine warmed up and running, SLOWLY POUR 1/3 to ½ can of Sea Foam down the carburetor throat or into any main manifold vacuum line that DISTRIBUTES EVENLY TO ALL CYLINDERS. Note that some newer induction systems, like those found on Vortec and Subaru “H” style engines, do not have any vacuum line that distribute evenly. Consequently, this process should only be attempted by technicians with a comprehensive understanding of the engine’s induction system or use Sea Foam Spray through the throttle body (discribed in a different section of this web site).

Once the product has been applied, turn off the engine and allow the Sea Foam to heat soak for a minimum of 10 minutes. At this time, Sea Foam will dissolve the varnish deposits that hold carbon together. After allowing the Sea Foam to soak, restart the engine in a WELL VENTILATED AREA as exhaust will be extreme for a short time. Drive aggressively for 2 to 5 miles to allow all the atomized carbon to be safely expelled from the system. REPEAT SEA FOAM TREATMENT AS NECESSARY.

Btw, I put some in my engine oil as per their instructions last fall before I did my final oil change of 2011, and I swear my lifter ticking has gone away. Mind you, it was always intermittent, but I think I'm going to do this everytime before I change my oil.

Speaking of oil changes- has anyone used the Scavenger oil change system?

I always add 3-4 oz to the oil 50 miles prior to changing it and believe it has helped. I also add 5 oz per tank once a month to clean up carbon build-up. never had any problems.

my Indy  uses the Scavenger on my bike  when servicing it,
  i like it very well does what it's sosposed to, cost me a little  to have it done with the additional labor and parts
but I,m happy

We spray it into the intake once hot and the engine is idling. Pop the air cleaner off,.. Use a multi purpose spray bottle. Let it sit, fire it back up. Sea foam works extremely well.

Oh you betcha
Change your oil when done

So it is fine to put in through the intake as long as you use a spray bottle- great info, thanks a lot.

Change the oil after doing the spray bottle cleaning through the intake?

   I use BG44K in the fuel tank two times a year. motor cycle is carbureted and truck is efi,what a differents it makes.

I do have a capped inlet on the top of my throttle body that is reserved for California related emissions equipment. And, I have read instructions (like minded forum) on how to create a tube, attache it to this inlet and utilize seafoam as a cleanser for the intake and top end.

I use the early edition on mine and I am pleased with the intended result at oil service. However, toss the spring/rings and use safety wire on the clam shells.

The product does not burn and some dilute it with water. Some ends up in the oil.
