Seafoam and wet clutches

Thinking of dropping some sea foam into my crankcase before my next oil change. Anyone know for sure that it will not harm the wet clutch in our bikes?

I used it on my Nomad, no problems at all.

Ride Safe.

Don't do it.

I don't claim to have knowledge of failures as a result, but I'd stay WAY far away from any additive in the case of a wet clutch tranny.

Do yourself the favor. Stick to the gas tank.

I actually wrote Seafoam about this very question.

Here's the exact email I sent them:
Quote:
Hello,

I was wondering if you could tell me if Seafoam is ok to use in the
crankcase of a motorcycle that has a “wet clutch” ?

I use Seafoam regularly in all my vehicles except my motorcycle and
simply did not because I was concerned about the effects it may have on
the wet clutch, since the engine and transmission oil are shared.

Is there any problems that Seafoam would cause in a wet clutch application, such as clutch slippage or premature wear?

Thanks for your help!

Here's the response that I got from the email:

Quote:
I sure hope you are experienced enough with Sea Foam to know running Sea Foam in your FUEL in this bike is a YES, as there is NO CONNECTION between the fuel system and wet clutch/oil system.

If not, DO IT!!!!!

As for your oil system/wet clutch shared oil, Sea Foam in the oil at 1 1/2 ounces per quart of that shared oil is what is recommended, to clean old Oil residue back into liquid and dry moisture to prevent ware.

This is your wet clutch's BEST KEPT SECRET

Now, judging by his response, he kinda sounds like a moron.

There's no connection between my fuel system and my wet clutch?
Uh... well DUH! I didn't say there was nor did I ask anything about it.

It also prevents "Ware" ???

Houseware, silverware, tupperware? Maybe he meant "wear".


... the Saga continues.


Seafoam makes a product called "Trans Tune".

I'd be more apt to use that in my wet clutch motorcycle (as of now)
than I would regular Seafoam.
Automatic transmissions have clutch packs very similar to the clutches
in our bikes... The "trans tune" should be better suited to the clutches
in the bikes than the regular Seafoam.

The best thing you can do is use a good quality oil and keep it changed... and you don't need to worry
about using a cleaning agent.

Gasoline is for washing parts, Alcohol is for drinking... NITRO is for racing!

In any event, Seafoam in the oil is only intended for very short durations -- dump in the crankcase, run the engine for some short period of time, then drain the oil and replace. Right?

Regular oil change intervals and mileage do *not* require any additives, of ANY type. It's simply not worth the risk to the clutch discs.

If you *really* feel like you need to do this, use something specifically for transmissions, as Litnin pointed out. Automatic transmissions are very similar in the compounds used and fundamental design of the clutches as the motorcycle wet clutches.

Please don't hammer in screws with a wrench, ok folks?

Well regardless of what is said and thought, I run some in mine all the time and so far no problems, I do not do the ounce and a half but just maybe a 1/2 ounce, have made some long runs with it in and like I said, "no problems for me", so guess it's an individual decision....
