Advice from bikers = Honda Shadow 600 VLX Motorcycle?

I believe re: carbs your friend is referring to SEAFOAM which is an additive you can get at most auto parts stores. You can put it in fuel tank and also run it through carbs and it does work like it says. You can go to youtube and do a search for seafoam or sea foam car seafoam motorcycle etc.. and it will show you a demo of it.
