How much seafoam is too much?

Postby bwagner6 » Sun Jun 03, 2012 7:05 am



I am trying to get my carbs to clear up (bad low speed stumble and carb pop)... Tried 1 tank with one ounce per gallon as per the instructions and don't notice any improvement. How much can be used? Bike runs fine at higher rpm.

thanks for the input....

I usually do 1/2 a can per full tank in the spring and the same before putting the bike away for the winter. I like to run it until the seafom mix is in the carbs then shut the fuel petcok off with the tank full. The seafoam works like stabil and keep the tank full to prevent condensation while sitting. Sometimes I will run 1/2 a can to a 1/2 full tank of gas to clean things out. Let it sit overnight with the seafoam mix in the carbs to do it's job. And don't forget to shut the petcock. It might smoke a bit but that's the nature of the seafoam. It may take a couple tanks to work, but if not you may need to clean and maybe rebuild the carbs.

You might need to synch your carbs. When was the last time that was done?

I dont think its ever been done to be honest... Bike is new to me so not sure. Only 5k on the ole girl. I dont have any gauges, or knowledge for that matter to do it so I may have to take it to a shop for that. Any clue what would be a reasonable price to pay for sync? Also If I sync them and no difference then pull and clean wont I need to sync again?

Could cost between $200 to $400 for a carb synch, depending on the shop you go to. I built my own gauge set because of that. I synch mine every spring. Takes about 20 mins to do it. Yes, any time you pull the carbs to work on them you should synch them. You can put a request out to see if another member is near enough to you to help you with the synch. If you were closer I'd do it for you. Good luck.

Do you synch more for preventative maintenance, or do the carbs start to "wonder" over the course of a years riding?

I'm a mechanic by trade so I like to do a lot of preventive maintenance on all my vehicles. The carbs will wander over time. How much depends on how much you ride. Another thing to consider is most 1200's have a spring to keep tension on the butterfly adjuster screws. Vibration causes the adjustment to change. The older 'wings have a lock nut. The first time I synched the carbs on my bike, (last owner did it when he first bought bike) the carbs were off quite a bit. The carb to carb synch wasn't too far off, but the left to right bank synch was way off. It made a big difference. This winter I plan on rebuilding the carbs along with a timing belt change.

I've seen seafoam take up to a couple of months to work. Just depends on how bad the are gummed up. You may have to clean them out. And I would also put some in the crank case.
