Out in the Rain

Needed to do some work in the garage this weekend. Had to refinish a door, so couldn’t fit the bike in overnight. We got a surprise thunderstorm Saturday night and the bike got soaked. In the morning I dried it off an put it inside. It rained Sunday and Monday so the bike sat. This morning I started it up and it wouldn’t idle and ran like garbage sputtering and choking for 16 miles to work. Thought it may be water in the gas, so I stopped halfway and put in 2.6 gals. Seems to be getting too much gas in the front cylinder. Tried re-staring it once I got to work. Just back fired and sputtered. Any thoughts one what’s wrong?

First thing I'd try is seafoam. Try a stronger than normal dose - one of the functions of seafoam is to remove moisture from the gas - so if that's your problem, it should clear it up...

If that doesn't work, most "fuel" problems are actually electrical...

Sitting in the rain shouldn't make the bike misbehave (mine sits in the rain more than I'd like to admit - though it's usually for only a couple hours at a time while I'm at school, work, etc.)

Moisture is of course one of your bike's biggest enemies.

I ride in the rain (it's actually a pretty neat experience--if you're wearing the right stuff), but only as conditions require.

May I suggest an easy to use cover, similar to the following:

Something like the above will keep your baby looking sharp a lot longer, and help keep rust formation in check.

You got water in something but I doubt it's the gas. Check the spark plug wells. There's a small hole in the bottom of each one that allows water to drain. Maybe one of them got plugged and you have water sitting around the spark plug. Pull the boot, blow it out with compressed air and see what happens. Make sure the forward right boot isn't rubbing on the throttle cable. That can happen if someone didn't route the throttle cable correctly.

Seems to have been a sticky float. I drained the carb and everything seems to be back to normal again. I will be running some seafoam through it too. I've never bought seafoam before, where can I find it?

Garage
ChinaMart is the cheapest around here, Advance auto and many other auto supply stores also have it, runs about $6 to $7. Comes in a round 16oz can.

Did a quick search. Looks like all the advance auto's around ya carry the stuff.
107 Pine Street, Manchester should be the closest.

Enter your zip at partsamerica.com and search for seafoam. Ya should be able to verify stock - and ya can order online and pickup in store...

Some walmarts carry seafoam, some (all around me) don't.

Picked up a can of Seafoam at lunch. How much should I add for a good cleaning? I'm just about to hit the fuel reserve too, should I add it in now so it'll be a bit more potent or fill up first?

Just put about 1/4 in now and shake it up good and run it like it is. Try that.

You probably got water in the fuel. there is a small drain screw at the bottom of the carbs, drain them out. Also use a water remover for fuel. One that I use is called (heet) it only cost about 2.00 for a car tank treatment, only use a small amount for the bike. Hope this helps you.
