HRM, I have been listening to you quys about the Seafoam and have been using it. Does the Seafoam help with a float in the carb though?

(Must out bike on center stand for this). Hawks are PICKY about the oil. I have to check mine every 3rd ride at the most. That seems to be the biggest culprit for blowing an engine. Before storing for the winter: Sta-bil and run the bike about 15 minutes. After: Seafoam and run for at least 15 minutes. I throw Seafoam in my bike all of the time. Keeps those carbs from sticking, cleans things up. Now we have another answer for the other gal in here that has gas in her air box filter too....stuck float perhaps. She could use some Seafoam too.

I didn't think to turn the gas off when I put the bike away for the winter (I know, I know), and I had a gas leak some time in January. At that point I turned the gas off. Last week I replaced the fuel line and took the bike for a spin, but it wasn't running quite right - it seemed like it wasn't getting enough gas. I drove it to a brother-in-law's house, where we determined that it was simply a kinked fuel line. But in the process we heard a gurgling sound coming from the air box, and we found that there was a lot of gas in it. A float in one of my carbs must have stuck in the beginning of winter, backfeeding gasoline into the air box. The gurgling sound must have been coming from the transmission breather tube that connects at the bottom of the air box. We drained the air box of all the gas, then proceeded to change my oil, which we were going to do anyway. Well, the oil was basically like gasoline with a little bit of oil in it, and I had driven the bike about 50 or so miles like that. After changing the oil we went on about a 100 mile ride. My bike always had a valve tick, but at one point, while I was on the interstate in heavy traffic, the noise changed and the bike felt different, but then it went back to normal. 2 miles later I lost all power, and I knew it was serious. My brother in laws think that a bearing was already starting to fail and this just helped it along, but I guess we'll never know. Is it possible to upload pictures using Google Groups? I have some shots of the damage if anyone is interested... Long story short: Gas in oil = bad. Turn off your fuel valve before winter, and check the oil before you take it for your first ride of the year.... I had to learn the hard way. I think I may have found a CB700SC engine or 2 locally... wish me luck. On Apr 20, 6:43 am, kiwi <[email protected]> wrote: > I'm curious. How did you throw a rod?
