I know that seafoam can be effective in degumming carbs delivered via the gas tank.  However, the seafoam instructions say it can also remove carbon build-up in the crankcase by adding it to the oil.  Has anybody tried this?  If so, should it be done shortly before planning to change the oil, or at least change the filter after a treatment period?  Have never used this type of additive in oil before.

get differing opinions on this subject.. I've use Sea-Foam for appr 30 yrs in fuel systems with good luck.. However, I'm not a big fan of oil additives.. If our bike has been given reasonable care over the years there really should not be enough crankcase deposits to worry about,, if any at all..Any carbon deposits would form on the valves and combustion chambers which is normal with any engine and a fuel additive may help with those.. Most folks that have motorbikes like these tend to take good care of them..

I have seen the results of oil additives including cleaners and found that most all are garbage. As for the cleaners in the oil once the engine is dirty inside the only real remedy is to be torn down and cleaned. If you use Marvel constantly then there may be some benefit and I have seen Marvel quiet a noisy lifter but outside of that frequent oil changes is the best protection. It really makes a difference in engine designs as to how clean the inside will be too. The Valks really don't seem to be dirty engines as some engines are so if you  have build up on the inside of your engine then you need to step up to the plate as far as the oil changes. I am not talking about dirty oil just buildup on the inside of the engine. As for combustion chamber or valves the modern fuels have more than enough cleaners to clean the valves as I have not seen almost any modern engine with deposits on the valves when the fuel hits it or even to much in the cylinder or the head of the piston. But I have seen deposits on the intake manifold in places not covered by the gasoline. The only other place that I have seen deposits of carbon is the piston rings and no oil additive used one or two times is going to touch this. Leaded gas was the biggest reason for deposits on the valves and combustion chambers.

i cant tell you what it can do in valk but i use it in the crankcase of all of yard machines .

its great!!!  i tore down a stihl blower and used some in the gas and the piston and cyl were
spotless     same with my lawn mower   i can only guess that it works with the valk


I use this stuff on my 94 trooper and it passes emissions every time both in the gas and crankcase
close to 150k on it

just two cents

I checked the seafoam website.  They gave some additional instructions regarding crankcase use.  The recommendation was to perform the treatment shortly before an oil change.  Recommended adding 1.5 oz per quart of oil to the crankcase and then driving (riding) 50 to 100 miles.  Then change the oil and filter.

I gave it a try.  It's been running better since I did the gas treatment -- stopped high rpm sputtering.  I'm not sure if the crankcase treatment did anything or not.
