Seafoam revisited

Post by jbeganny » Wed Sep 11, 2013 10:05 pm

How much seafoam is enough and how much is too much? I tried it once and it did not make much difference. Should I try it again? I hate the thought of having to service the carbs.

I can't say how much is too much. I've put an entire can in a tank before, when the bike was really bad.

On my wife's PC800, the carbs were so bad it was barely running. If you rode it hard for a bit, it would clear up, but let it sit overnight, and it was hard to start and keep running again. I put a whole can in its tank, and made no difference. So I decided to try something drastic. I pulled the hose off the fuel tank, put a funnel in it, and slowly poured in Seafoam. It eventually got through and the bike was running on 100% Seafoam, no gas at all. It didn't like this very much. I then shut it off and let it sit overnight.

The next day I hooked the gas back up, cranked it until it started (it refused to start on 100% Seafoam), and it never had a problem again.

Try this. It works great although it sounds a bit nuts, it isn't (check what seafoam really is) 2 oz of naphtha, 2oz of acetone, 2oz kerosene (diesel) 1/2 oz of trans. fluid. Combine and add to a full take of fuel. The trans fluid is to lube the cycl walls. I use it in all the bikes, truck and car

I have never used seafoam. Back when I bought a '75 that was running a bit rough I used store brand card cleaner, both liquid and spray. On that bike it was easy to spray it into the air intake after removing the filter. I didn't know about seafoam then but the carb cleaner worked well and did the job. You have to use a lot. About half the bottle to a tank of gas is what I used.
Now I use it spring and fall in the car and bike. I don't winterize my bike. I can usually get at least one or 2 rides in every month over the winter.
